WebDriverManager Implementation with Selenium WebDriver.

WebDriverManager is an API that allows users to automate the handling of driver executables like chromedriver.exe, geckodriver.exe etc required by Selenium WebDriver API.

Now let us see, how can we set path for driver executables for different browsers like Chrome, Firefox etc. in a traditional way.

In general, to automate web applications we need to download driver executables manually for required browsers. Once driver executables are downloaded into local system then we need place them in a specific path and set path for driver executables that becomes very tedious task to maintain driver executables as and when browser version changes.

In below code, we can see how to set path for driver executables in a traditional way.

//For Chrome Browser
System.setProperty("webdriver.chrome.driver", "./Drivers/chromedriver.exe");

//For Internet Explorer Browser
System.setProperty("webdriver.ie.driver", "./Drivers/IEDriverServer.exe");

//For Firefox Browser
System.setProperty("webdriver.gecko.driver", "./Drivers/geckodriver.exe");

It’s a good practice to maintain driver executables under project directory as shown below.

Now let us see the disadvantages of following traditional approach over WebDriverManager to maintain driver executables and setting path for the same.

1. We need to download driver executables manually and set path for the same.

2. As and when browser version is updated, we need to download driver executable/s that can be matched with latest browser version.

3. We need to set exact path for driver executable/s else we get illegalStateException. [When we try to launch browser without setting correct path for driver executable/s]

Now the question is how can we overcome doing above manual stuff using WebDriverManager.

Pre-Condition:

Project should be Maven. In pom.xml file we need to add below dependency to have WebDriverManager in our Project.

<dependency>
	<groupId>io.github.bonigarcia</groupId>
	<artifactId>webdrivermanager</artifactId>
	<version>3.7.1</version>
</dependency>

Once WebDriverManager is added into pom.xml. Update Maven Project and ensure that WebDriverManager Jar is added into Project Build Path under Project Maven Dependencies folder as shown below.

 

Notice that simply adding WebDriverManager.chromedriver().setup(); 

WebDriverManager does magic for you:

  1. It checks the version of the browser installed in your machine (e.g. Chrome, Firefox).
  2. It checks the version of the driver (e.g. chromedrivergeckodriver). If unknown, it uses the latest version of the driver.
  3. It downloads the WebDriver binary if it is not present on the WebDriverManager cache (~/.m2/repository/webdriver by default).
  4. It exports the proper WebDriver Java environment variables required by Selenium (not done when using WebDriverManager from the CLI or as a Server).

WebDriverManager resolves the driver binaries for the browsers ChromeFirefoxEdgeOperaPhantomJSInternet Explorer, and Chromium. For that, it provides several drivers managers for these browsers. These drivers managers can be used as follows:

WebDriverManager.chromedriver().setup();
WebDriverManager.firefoxdriver().setup();
WebDriverManager.edgedriver().setup();
WebDriverManager.operadriver().setup();
WebDriverManager.phantomjs().setup();
WebDriverManager.iedriver().setup();
WebDriverManager.chromiumdriver().setup();

 

 

Now we are good to use WebDriverManager in Test Scripts.

//For Chrome Browser
WebDriverManager.chromedriver().setup();

//For Internet Explorer Browser
WebDriverManager.iedriver().setup();

//For Firefox Browser
WebDriverManager.firefoxdriver().setup();

Likewise we can setup driver executables for other browsers like edge, opera etc using WebDriverManager which launches a browser.

//Below is the sample code to launch Chrome Browser using WebDriverManager
public class WebDriverManagerChrome 
{
        @Test
	public void webDriverManagerChrome()
	{
		WebDriverManager.chromedriver().setup();
		WebDriver driver = new ChromeDriver();
		driver.manage().window().maximize();
		driver.manage().deleteAllCookies();
			
		driver.manage().timeouts().pageLoadTimeout(30, TimeUnit.SECONDS);
		driver.manage().timeouts().implicitlyWait(15, TimeUnit.SECONDS);
		
		driver.get("https://classic.crmpro.com/index.html");
         }
}

When we setup WebDriverManager in Project. By default, it downloads the latest version for a specified driver executable/s. Using WebDriverManager, we can also setup driver executable/s for a specific browser version.

//Code Snippet for Chrome Browser
WebDriverManager.chromedriver().version("2.40")

Now let us see the difference between WebDriverManager and Traditional way of setting up driver executables to launch browsers.

WebDriverManager.chromedriver().setup(); ==>> It will automatically downloads the Driver Executable/s.

System.setProperty(“webdriver.chrome.driver”, “./Drivers/chromedriver.exe”); This will setup driver executable for a specific browser based on the location that we have provided where we downloaded and placed driver executable/s.

Note: WebDriverManager is not part of Selenium WebDriver API.

Refer below Git Repository for WebDriverManager implementation with Maven Project.

In this blog, we have seen setting up WebDriverManager for a Maven Project to work with Selenium WebDriver API.

Actions Class in selenium WebDriver for User Actions

1.Overview

In this article, we are going to explore the most fundamental phenomenon that is Actions class in selenium WebDriver.

2. Actions Class

  • We have performed single actions like sendKeys, click event till now.
  • But there are events where we need to perform multiple actions like drag and drop, right-click or pressing a key from the keyboard etc.
  • So here comes the Actions class to deal with such composite actions.
  • By selenium documentation, they have defined the Actions class as:

Actions Class
  • In simple terms, Actions class handles various types of keyword and mouse events and is available under package 
import org.openqa.selenium.interactions.Actions;
  • Syntax:
Actions actions = new Actions(driver);
  • For creating an object of an action class, you need to pass the driver object to the constructor of action class like the following :

Methods in Actions Class

Now, you can perform any composite actions as shown above with the action object. We will see a couple of examples below where composite actions are being performed.

To Note: There are two major methods in actions class are build and perform.

build() compiles all the steps into a single step and then perform() executes the step, also for single-step perform() method can be used, then there is no need to execute the build() method.

3. Mouse Hover with Actions class

  • A mouse hovers cause an event to trigger actions such as where a user places a mouse over a particular element like hovering over a tab or link. 
  • moveToElement is the method used for hovering action:

Mouse Hovering Methods

Let’s understand moveToElement(WebElement target) by code:

package com.selenium.sessions;

import org.junit.jupiter.api.Test;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.interactions.Actions;

/**
 * 
 * @author Mandeep kaur
 * @Date May 19,2020
 */
public class ActionClass {

	@Test
	public void performsActionClass() throws InterruptedException {

		String path = System.getProperty("user.dir");
		System.setProperty("webdriver.chrome.driver", path + "/src/main/resources/chromedriver");

		System.setProperty("webdriver.chrome.silentOutput", "true");
		WebDriver driver = new ChromeDriver();

		driver.get("https://www.makemytrip.com/visa/");

		// Locate more element on the web page
		WebElement moreObj = driver.findElement(By.xpath("//li[10]/a/span[2]/span[1]"));

		Thread.sleep(1000);

		// Locate International Hotels once hovered over more element
		WebElement moveToInternationalHotels = driver.findElement(By.xpath("//li[10]/div/a[3]"));

		Actions action = new Actions(driver);

		// hover to More element then hover to International hotel and build the steps
		// in singe unit and perform the step
		action.moveToElement(moreObj).moveToElement(moveToInternationalHotels).build().perform();

		Thread.sleep(1000);
		driver.close();

	}

}

Explanation :

First, we found out the elements where mouse hovering is required i.e more element and other is International hotels.

Then we are hovering over these elements with the moveToElement method, post that we build these steps it in a single unit using build() method and execute it with perform() method.

And we can see the above code output as:

Now, Let’s proceed with other method moveToElement(target, xOffset, yOffset);

This method is used to take the mouse on particular points on target elements.

The following is an example to deal with a slider:

Now the scenario is we need to move this slider, but how do we do that?

Let’s see the below code first to achieve this task:

package com.selenium.sessions;

import org.junit.jupiter.api.Test;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.interactions.Actions;

/**
 * 
 * @author Mandeep kaur
 * @Date May 19,2020
 */
public class ActionClass {

	@Test
	public void moveToElementOffset_whenSuccess() throws InterruptedException {

		String path = System.getProperty("user.dir");
		System.setProperty("webdriver.chrome.driver", path + "/src/main/resources/chromedriver");

		System.setProperty("webdriver.chrome.silentOutput", "true");
		WebDriver driver = new ChromeDriver();

		driver.get("https://jqueryui.com/slider/");

		// Get the location of IFrame
		WebElement iFrame = driver.findElement(By.xpath("//iframe[@class='demo-frame']"));

		driver.switchTo().frame(iFrame);

		// get the slider element
		WebElement slider = driver.findElement(By.xpath("//div[@id='slider']"));

		// Get the location of X,Y coordinates
		System.out.println(slider.getLocation());

		Thread.sleep(1000);

		Actions action = new Actions(driver);

		// move the element on target by X , Y coordinates
		action.moveToElement(slider, 8, 8).click().build().perform();

		Thread.sleep(1000);

		driver.close();
	}

}

Let’s break the code into the statement to get the clarity of the concept:

  1. First, we need to locate the frame, as the slider is present in the frame.

Let’s discuss little about iFrames, what are these:

  • iFrames stands for an inline frame. It is like another web page within a web page. 
  • In this case, a different document is used to embed within the current HTML document.
  • when you execute any method say findByElement for an element present in an iFrame, it will throw an exception as an element not found. 
  • For this, we first need to switch the focus to the frame to get the Element.
  • Syntax: driver.switchTo().frame();

Switching to Frame

And most importantly how we will get to know that frame is present or not, for that you need to right-click on the element and you will get View Frame Source like below

And in DOM you will get to see an iFrame tag

where <iframe> tag states an inline frame.

We can switch to the frame by index , by frame name or id or by WebElement.

2. In the above code, we have to switch the frame with WebElement.

3. Find the target element and get the location of X and Y coordinates by using getLocation().

4. Once we got the coordinates then we can slide the cursor accordingly by passing the target, x and y coordinates:

action.moveToElement(slider, 8, 8).click().build().perform(); 

 As can be seen below our slider has moved with coordinates given:

4. Drag And Drop with Actions Class

Now, there are situations where we need to perform drag and drop operation. We can also perform this scenario with the action class.

  • There is a method called dragAndDrop which drags a source element and drops on a target element.
  • We need to solve the scenario given below

Drag and Drop Image

So, here we just have to put “Drag me to my target” box to “Dropped!” box

Let’s do it by code:

Code for Drag and Drop

package com.selenium.sessions;

import org.junit.jupiter.api.Test;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.interactions.Actions;

/**
 * 
 * @author Mandeep kaur
 * @Date May 19,2020
 */
public class ActionClass {

	@Test
	public void dragAndDropExample_whenSuccess() throws InterruptedException {

		String path = System.getProperty("user.dir");
		System.setProperty("webdriver.chrome.driver", path + "/src/main/resources/chromedriver");

		System.setProperty("webdriver.chrome.silentOutput", "true");
		WebDriver driver = new ChromeDriver();

		driver.get("https://jqueryui.com/droppable/");

		// Get the location of IFrame
		WebElement iFrame = driver.findElement(By.xpath("//iframe[@class='demo-frame']"));

		driver.switchTo().frame(iFrame);

		// get the source element 
		WebElement source = driver.findElement(By.id("draggable"));

		// get the target element 
		WebElement target = driver.findElement(By.id("droppable"));

		Thread.sleep(1000);

		//create an object of Action class
		Actions action = new Actions(driver);
		
		// perform drag and Drop operation
		action.dragAndDrop(source, target).build().perform();

		Thread.sleep(1000);
		
		driver.close();

	}

}

So, it’s pretty clear from the above code that first it requires us to switch to the iframe as the elements are present in an iframe. Then we have to find our source and target element and just perform dragAndDrop Operation on it as has been done for you above.

And the output will be shown as follows:

 We can also have another example where certain actions need to be performed from Keyboard. User has to send some inputs from the Keyboard.

Let’s see this happening in the following example in the code:

As described in the above code, first we find the elements where keyboard actions have to be performed then with movetoElement function we move to userName element and KeyDown function to  press the shift key and sending the userName in upper case, post that KeyUp function  to  release the shift key and next we are highlighting the userName

In the end, we are clicking on signUp button with the help of Enter Key.

package com.selenium.sessions;

import org.junit.jupiter.api.Test;
import org.openqa.selenium.By;
import org.openqa.selenium.Keys;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.interactions.Action;
import org.openqa.selenium.interactions.Actions;

/**
 *
 * @author Mandeep kaur
 * @Date May 19,2020
 */
public class ActionClass {

@Test
public void keyBoardEvents_whenSuccess() {

String path = System.getProperty(“user.dir”);
System.setProperty(“webdriver.chrome.driver”, path + “/src/main/resources/chromedriver”);

System.setProperty(“webdriver.chrome.silentOutput”, “true”);
WebDriver driver = new ChromeDriver();

driver.get(“https://www.facebook.com/“);

WebElement userName = driver.findElement(By.xpath(“//*[@name=’firstname’]”));

WebElement signUp = driver.findElement(By.xpath(“//*[@name=’websubmit’]”));

// In this step, we are moving the userName element and KeyDown function press
// the shift key and sends the userName and KeyUp function perform release the
// Key and next we are highlighting the userName


Actions builder = new Actions(driver);
builder.moveToElement(userName).click().keyDown(userName, Keys.SHIFT).sendKeys(userName, “testuser”)
.keyUp(userName, Keys.SHIFT).doubleClick(userName).build().perform();

// Enter the sign up keys after we passed the userName

signUp.sendKeys(Keys.ENTER);

driver.close();
}
}

5.Conclusion

In this article, we learnt about Actions class and how we can perform various composite actions using actions classes.

Thanks for reading it!

An alternative to :nth-child

As test automation engineers, we strive to use stable and self-documenting selectors whenever possible, but sometimes using an XPath-like selector is unavoidable. The :nth-child() CSS pseudo-class, which selects an element based on its position amongst its siblings, is often used within these longer selectors. But did you know there’s an alternative to :nth-child() which is a better choice in almost every circumstance?

Element Selection

Choosing good locators is an important aspect of creating stable automated tests, reducing false-positive error rates by ensuring the correct element continues to be selected even for pages under heavy development. There are well-documented locator strategies that you can follow when crafting these locators, but even if you’re following best-practices you may find yourself in situations where an optimal locator cannot be generated:

  • Your web application uses a CSS-in-JS library: Libraries such as Styled Components and EmotionJS allow developers to define CSS styles alongside their web components instead of in separate CSS files. Defining the styling, template, and logic all inside a single JS file makes each component self-contained which helps maintainability and readability, but it comes at cost; the classes that are output by these libraries are auto-generated and lack any semantic meaning. This means that you’re going to have a bad time if you rely on these classes in your test automation. Worse yet, they have the potential to change with every new build.
  • You’re not using data attributes as stable locators: Depending on your situation, adding attributes in your application-under-test that are specifically for use by your test automation scripts may be the best way to achieve stable locators. While this offers the greatest flexibility in terms of generating locators, many teams don’t have commit-access to the application-under-test, and asking developers to do this may not be an option.
  • You want to target the ‘nth’ element in a list of elements: Even with great locators or the ability to add automation-specific data attributes, you may want to simply target a specific element among a list of elements. In cases like this it often doesn’t make sense to add a data-attribute since the attribute value may simply be an index value rather than a self-describing value like a product name or username.

In these and other situations, you’ll often find yourself using :nth-child() as part of your locator.

Using :nth-child()

:nth-child() is a CSS pseudo-class that’s supported in all major browsers and in legacy browsers including IE9. MDN defines its behavior as “match[ing] elements based on their position in a group of siblings.” In addition to its original intended use in CSS stylesheets, it’s ubiquitous in test automation scripts the world over. In fact, if you’ll often see it in selectors generated using Chrome Dev Tools’ Copy selector command.

A classic example of using :nth-child() is selecting the nth item in a list. In situations like this, you don’t want to use a locator that targets on a text value, since the item associated with that text value may change positions or may not be present at all in the future. :nth-child() is a succinct way of expressing the intention to choose not based on an element’s value, but based on its position.

But problems can arise with this approach that are not at all obvious due to how this pseudo-class works.

Drawbacks

Let’s assume you want to target the second element in the following list:

Item 1

Item 2

Item 3

The selector that you’d typically write is #list > .item:nth-child(2). If you’re using Chrome Dev Tools’ Copy selector feature to generate the selector for you, then it’s going to output the inferior #list > div:nth-child(2) selector that targets against the child’s tag name instead of class name. But let’s suppose you wanted to choose the 2nd element even if the class or tag name changes, maybe to avoid the case where a developer changes the tag name and causes your test to break. You instead use the selector #list > *:nth-child(2) which will select the 2nd element regardless of tag or class.

So far so good, but let’s consider a scenario where the page-the-under test is running ads. Often times ad platforms will generate Javascript code by dynamically inserting script tags. Using the example above, the DOM may end up in a state like this:

Item 1

Item 2

Item 3

In this situation, neither selector used above will return the expected result! #list > .item:nth-child(2) will return null because the nth child to #list is not a div! #list > *:nth-child(2) doesn’t fare much better, returning the script element.

This is a contrived example, but you would be surprised how often I’ve seen this in the wild. The automated testing tool I co-created has a feature that auto-generates selectors, and for this reason it will never generate a selector containing :nth-child, but instead uses the :nth-of-type pseudo-class.

Recommendation

:nth-of-type(), like :nth-child(), is supported by all major browsers and has subtlely different behavior in that it “matches elements of a given type, based on their position among a group of siblings”. This behavior has the distinct advantage of being closer to representing how elements actually appear within the browser. Since :nth-of-type() allows you to target on the position of a given tag, you’ll never hit a situation where a non-visible tag like script causes your tests to fail, since it ignores any elements not matching that tag in the test. In the examples above, the selector #list > .item:nth-of-type(2) matches the Item 2 element in the original example as well as the example where a script tag is the second child. This is because it ignores any elements that don’t include the item class.

In conclusion, by coupling :nth-of-type() with a stable sub-selector like .item, you get the benefit of a built-in way to target based on position (avoiding creating unnecessary data-attributes) while avoiding the potential pitfalls of :nth-child(). Consider migrating your tests over to use :nth-of-type()!

 

That’s all about :nth-of-type() in CSS Selector.

Handling Browser Window PopUp in Selenium WebDriver

1. Overview

In this article, we will discuss the concept of browser window popup also the practical implementation to handle the browser window popup with selenium web driver.

2. Browser window Popup

  • Browser window popup is a window popup that suddenly pops up on after clicking on some link or on selecting an option. It just likes another web page where maximization and minimization of the web page can be done.
  • This is having its own title and url or it could be an advertisement pop up also.
  • When do we need to handle this browser window popup: if the scenario is something like: you click on some link on the main window (parent window) and some other screen pops out just another webpage (child window ), now child window demands to submit some important information and press OK once information is filled.
  • Let’s see how the browser window appears:

Browser window popup Example

3. Steps to deal with browser window popup

1. Operate on the main window that opens the popup window. For instance, click on some link on the main window.

2. Need to know the name or id of the popup window. The window Id can be fetched from Window Handler API available in selenium. it uniquely identifies the address of all the windows open at a time. Below are the methods to handle the windows:

Syntax:

driver.getWindowHandle();

  • This function allows the handling of the current window by getting the current window Handle.
  • It returns the type String.
  • On the selenium official site, this is defined as


String parentWindowObj = driver.getwindowhandle();

driver.getwindowhandles();

  • As the method name suggests windowHandles, that means there are multiple windows and to handle all these opened windows we have to use this function.
  • It returns the Set of String.
    • Set<String> handles = driver.getwindowhandles();
  • Set stores the unique values and handle of all the windows that will be unique.
  • Below description clearly says the same:
  • Set values are not stored based on the index, so to iterate over the set, we need to use the Iterator to get the handler values and this method will give you an iterator of string.
  • This Iterator will be available in java. util package.
Iterator<String> it = handler.iterator();

//get the window ID for Parent a& Child now
String parentWindowID = it.next();
String childWindowID = it.next();

3. switch the driver to the popup window

driver.switchTo.window(childWindowID);

4. Perform some actions in the popup window such as get the title or close the button/tab etc.

driver.switchTo().window(childWindowID);
String title = driver.getTitle();
System.out.println("child window title is : " + title);

//close the pop up window now by using driver.close() method.
driver.close();

tip: Make sure, you are using close() to close the pop up. If you use quit() it will close parent and child both.
This is the basic difference between close() & quit().

5. Switch back to the parent window by passing the parentWindowID.

driver.switchTo().window(parentWindowID);
String title = driver.getTitle();
System.out.println("parent window title is : " + title);

//close the parent window by using quit:
driver.quit();

Let’s see the below code for a complete understanding of the concept:

Full code to handle Browser window popup:
package SeleniumSessions;

import java.util.Iterator;
import java.util.Set;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import io.github.bonigarcia.wdm.WebDriverManager;

public class BrowserWindowPopUp {

public static void main(String[] args) {

WebDriverManager.chromedriver().setup();
WebDriver driver = new ChromeDriver();

driver.get(“http://www.popuptest.com/goodpopups.html”);

driver.findElement(By.linkText(“Good PopUp #3”)).click();

Set<String> handles = driver.getWindowHandles();

Iterator<String> it = handles.iterator();

String parentWindowID = it.next();
System.out.println(“parent window id is : ” + parentWindowID);

String childWindowID = it.next();
System.out.println(“child pop up window id is : ” + childWindowID);

driver.switchTo().window(childWindowID);

System.out.println(“child window title is ” + driver.getTitle());

driver.close();

driver.switchTo().window(parentWindowID);
System.out.println(“parent window title is ” + driver.getTitle());

}

}

Important Tip:

One thing to notice here is that we have to come back to parent window if any further actions have to performed on Parent window. Without switching to parent window will not allow us to perform any action on parent window page.

Let’s add another example to get more understanding of the concept:

Suppose four windows are open and we want to switch to the third window.  

  • First Approach: using Set and iterator we have already seen above.
  • Second Approach: Using ArrayList. The benefit of this approach is you can easily deal with any window. The parent window will start with an index 0.

Let’s see the code with ArrayList:

package SeleniumSessions;

import java.util.ArrayList;

import java.util.Set;

import org.openqa.selenium.By;

import org.openqa.selenium.WebDriver;

import org.openqa.selenium.chrome.ChromeDriver;

public class BrowserWindowHandleList {

public static void main(String[] args) {

System.setProperty(“webdriver.chrome.driver”, “/Users/NaveenKhunteta/Downloads/chromedriver”);

WebDriver driver = new ChromeDriver();

driver.get(“http://www.popuptest.com/goodpopups.html”);

driver.findElement(By.linkText(“Good PopUp #3”)).click();

Set<String> handles = driver.getWindowHandles();

ArrayList<String> ar = new ArrayList<String>(handles);

System.out.println(ar);

String parentWindowID = ar.get(0);

System.out.println(parentWindowID);

String childWindowID = ar.get(1);

System.out.println(childWindowID);

driver.switchTo().window(childWindowID);

System.out.println(“child window title is “ + driver.getTitle());

driver.close();

driver.switchTo().window(parentWindowID);

System.out.println(“parent window title is “ + driver.getTitle());

}

}

 

And we’ll get the output as following:

As can be seen through the above code, you can easily browse through the windows following this approach.

6. Conclusion

We have learnt to handle  browser window popup using windowhandler API in Selenium WebDriver. We have solved this use cases by using Set and List both.

That’s about it.

JS Alert Popup, Auth Pop Up and File Upload Pop Up Handling in Selenium WebDriver

1.Introduction

In this article, we’re going to illustrate how to handle alert or javascript Popup using selenium WebDriver.

2. Basics

Let’s get started by understanding what are these alerts or javascript popups.

  • Javascript Alert/popup is a notification/warning or message displayed on the User interface in box format to notify the user about some information or asks for permission to perform certain kind of operations.
  • Alert is a method in javascript and  displays an alert box with a specified message and an OK button.
  • what do we need to generate this alert on UI is simply open inspect window and click on console and type alert(“Hi this is an automation User!!”) . 
  • you will be able to see the popup similar to this:

3. Types of Alerts

  1. Simple Alert
  2. Confirmation Alert
  3. Prompt Alert

Let’s have a look at the first one:

Simple Alert:

This alert is called simple alert because it just notifies the user some information or warning with an “OK” or “Close” button as shown in the following image.

  • The above popup can not be handled with finding XPath of OK Button as we can not inspect or spy over this button.
  • So, to handle the above Popup, we need to look at Alert interface of selenium WebDriver

Alert Interface

  • Alert is an interface in selenium provide some methods to handle the alert
  • Syntax:
  • Alert alert= driver.switchTo().alert();
  • To handle the Alert, we first need to switch to alert using switchTo() method.
  • WebDriver interface contains method switchTo() which has return as interface and contains method alert() which has return type as Alert interface. 
  • RemoteAlert class in RemoteWebDriver class implement this Alert Interface
  • For complete code reference, visit over
  • RemoteWebDriver Implementation
  • alert() switches to the alert and return an alert reference and throw “NoAlertPresentException” if no alert exists.
  • Next, Let’s what actions we can perform once we switched to an alert

1.void dismiss(): This method clicks on the ‘Cancel’ button of the alert or dismiss the popup . It returns void.

Syntax:

driver.switchTo().alert().dismiss();

2.void accept(): This method click on the ‘OK’ button of the alert and returns void

Syntax:

driver.switchTo().alert().accept();

3.String getText() : This method captures the alert message and returns the String.

Syntax:

driver.switchTo().alert().getText();

4.void sendKeys(String Text):This method passes some data to alert input text and it returns void 

Syntax:

driver.switchTo().alert().sendKeys(“Text”);

Back to simple alert , let’s see following snippet code

 

Simple Alert

As can be seen, for simple Alert we just need to click on OK button and with one statement by switching to alert and accepting it we can achieve this scenario.

  • Confirmation Alert

  • Confirmation Alert is the alert which asks for confirmation from the user to perform certain actions.
  • User can opt for OK or Cancel button based on the requirements and also we can not inspect over this alert also.
  • Let’s see how it looks like

Following code snippet for the same:

package com.example.automation;
import org.openqa.selenium.Alert;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;

/**
 * @author Mandeep Kaur
 * @Date 6 May,2020
 */
public class SeleniumConfig {
    public static void main(String[] args) throws InterruptedException {
        String path = System.getProperty("user.dir");
        System.setProperty("webdriver.chrome.silentOutput", "true");
        System.setProperty("webdriver.chrome.driver", path + "/chromedriver");
        WebDriver driver = new ChromeDriver();

        driver.get("https://testuserautomation.github.io/Alerts/");
        driver.findElement(By.xpath("//button[2]")).click();

       Alert alert = driver.switchTo().alert();
       System.out.println(alert.getText());
        //For OK button in alert, accept the PopUp
        alert.accept();
        Thread.sleep(2000);
        WebElement text =driver.findElement(By.xpath("//*[@id='demo']"));
        //verify the text after accepting the popUp
        System.out.println(text.getText());
        driver.close();

    }
}

As shown in the code, we have accepted the alert and verify the text we got after running the above piece of code and we get output similar to:

  • Prompt Alert

  • This Alert is to get input from the user in the form of text.
  • From the above methods, we have to use alert.sendKeys() method to send the text in an alert
  • After entering the input, the user can press the OK or Cancel Button.
  • Let’s prompt Alert on UI

 

prompt Alert

Now , see the code snippet for the same:

package com.example.automation;
import org.openqa.selenium.Alert;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;


/**
 * @author Mandeep Kaur
 * @Date 6 May,2020
 */
public class SeleniumConfig {
    public static void main(String[] args) throws InterruptedException {
        String path = System.getProperty("user.dir");
        System.setProperty("webdriver.chrome.silentOutput", "true");
        System.setProperty("webdriver.chrome.driver", path + "/chromedriver");
        WebDriver driver = new ChromeDriver();

        driver.get("https://testuserautomation.github.io/Alerts/");
        driver.findElement(By.xpath("//button[3]")).click();

       Alert alert = driver.switchTo().alert();
       System.out.println(alert.getText());
       //Send Text to the Alert
        alert.sendKeys("TestAutomationUser!!");
        //For OK button in alert, accept the PopUp
        alert.accept();
        Thread.sleep(2000);
        WebElement text =driver.findElement(By.xpath("//*[@id='test']"));
        //verify the text after accepting the popUp
        System.out.println(text.getText());
        driver.close();

    }
}

We can see that here before accepting the Popup, we have sent the “TestAutomationUser” to the alert and verified the text after we accepted the popup and output will be like following

 
 
 
Do we have some other pop ups as well? 
Answer is YESSS…
 
 
Now, there are few other Popups such as Authentication popup and window-based  popup like file Upload , we need to have strong understanding to tackle such popups :
Let’s quickly discuss about Basic Authentication Popup First: 
 
1) Basic Authentication popup : It asks user to enter username and password to the popup  when the browser gets launched and it looks like something :
As can be comprehended from the above snapshot that we need to pass username and password and we can’t spy over this popup.
Let’s look at below code snippet to handle this popup

 

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;

/**
* @author Mandeep Kaur
* @Date 6 May,2020
*/
public class SeleniumConfig {
public static void main(String[] args) throws InterruptedException {
String path = System.getProperty(“user.dir”);
System.setProperty(“webdriver.chrome.silentOutput”, “true”);
System.setProperty(“webdriver.chrome.driver”, path + “/chromedriver”);
WebDriver driver = new ChromeDriver();

//send username : admin and password: admin in url before launching the browser
driver.get(“https://admin:admin@the-internet.herokuapp.com/basic_auth”);

//validate if popup is closed successfully and capture the text

WebElement successMessage = driver.findElement(By.xpath(“//div[@class=’example’]//p”));

System.out.println(successMessage.getText());

}
}

It’s pretty clear from the above code that we just need to pass the username and password in the URL and after “@” the complete URL, after that, we can verify the success message, this is how we can achieve our goal.

2) Window-based File Upload popup :

Window-based popup interacts with window operations, selenium doesn’t provide direct support to handle this type of popup  but there is a workaround to operate on such cases. let’s look down to understand this in detail:

Window/ Mac-based popup appears like this once you click on choose file:

Let’s see the code to handle this popup:

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;

/**
* @author Mandeep Kaur
* @Date 6 May,2020
*/
public class SeleniumConfig {
public static void main(String[] args) throws InterruptedException {
String path = System.getProperty(“user.dir”);
System.setProperty(“webdriver.chrome.silentOutput”, “true”);
System.setProperty(“webdriver.chrome.driver”, path + “/chromedriver”);
WebDriver driver = new ChromeDriver();

//launch the url
driver.get(“https://the-internet.herokuapp.com/upload”);

//inspect over the choose file element and send File from your directory to it
WebElement uploadFile = driver.findElement(By.xpath(“//input[@name=’file’]”));
uploadFile.sendKeys(“/Users/Documents/index.html”);

//click on upload button
driver.findElement(By.xpath(” //input[@class=’button’]”)).click();

//verify the message
WebElement successMessage= driver.findElement(By.xpath(“//div[@class=’example’]//h3”));
System.out.println(successMessage.getText());

driver.close();
}
}

Explanation:

1. We first need to inspect over choose file Button and capture XPath, HTML to look like below where it should have <input> tag and type should be file:

<input id=”file-upload” type=”file” name=”file” xpath=”1″>

 

2. Next, need to send File to upload using sendKeys(String fileNameWithExtension);

3. It will upload the file and we can verify the file is uploaded or not by capturing the success message like following:

4. Conclusion

In this write-up, we have learnt about javascript alerts, a few other types of popups and various ways to handle all these popups.

 

That’s all for this post, hope you have learnt about PopUps 🙂

 

Cheers!!

Image Resolution Issue in HeadLess Mode

If you have seen this strange issue while running the test in HeadLess mode. You might be getting lower resolution of the images or thumbnail png’s from the site.

Please use below code:

ChromeOptions options= new ChromeOptions();
options.addArguments(“window-size=1400,800”);
options.addArguments(“headless”);
WebDriver driver =  new ChromeDriver(options);

You can also use Dimension class from Selenium:

Dimension dim = new Dimension(width,height)
driver.manage().window().setSize(dim)

Server is checking the headless browser as not needing the higher resolution of the images. This solution will help you to set the widnow-size to “1400,800”. You can try this and take the screenshot of the page. in Headless. You should get higher resolution and clear images.

This is just a small trick 🙂

Difference between ImplicitlyWait, ExplicitWait and FluentWait in Selenium WebDriver

1.Overview

In this article, we’ll look at the most fundamental mechanism in selenium – synchronisation(wait).

2. Synchronisation in Selenium

  • Synchronisation helps the user to troubleshoot issues when launching or navigating to different web pages while executing the selenium scripts.
  • When the entire web page gets refreshed or elements are getting re-loaded there should be synchronisation between the selenium scripts, script execution speed and web application speed.
  • At times, there can be a lot of Ajax components or some images and when we want to interact with these elements it may not visible. Thus, a time fall back can be seen in such cases and we get an exception as “ElementNotVisibleException“.
  • Selenium doesn’t provide any default synchronisation but it provides synchronisation in the form of different types of waits which we will see below.

3. Different Types of waits in Selenium WebDriver

  • Implicit Wait
  • Explicit Wait
  • Fluent Wait

These waits are dynamic waits. To understand the statement let’s consider a situation when you have given a TimeOut value of 20 seconds. If the element is loaded in 5 seconds, then rest 15 seconds will be ignored.

Let’s have a look at each one of these commands:

  1. Implicit Wait

As per Selenium Documentation, An implicit wait is to tell WebDriver to poll the DOM for a certain amount of time when trying to find an element or elements if they are not immediately available. The default setting is 0. Once set, the implicit wait is set for the life of the WebDriver object instance.

  • Implicit wait waits for a certain time till page gets loaded. After setting a particular time web driver will wait for that time before throwing an exception “No Such Element Exception“.
  • Implicitly wait is applied globally, which means it is always available for all the web elements throughout the driver instance.
  • Syntax: driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
  • Implicitly accepts two parameters the first parameter time: 10 given as timeout wait and other is TimeUnit can be given in seconds, minutes, hours days just put dot key after TimeUnit, we can see all the options available.

Implicit Wait
 

So do I need to use Implicitly Wait? Answer is really NO..

Dis-advantages of Implicitly Wait:

  • undocumented and practically undefined behaviour.
  • runs in the remote part of selenium (the part controlling the browser).
  • only works on find element(s) methods.
  • returns either element found or (after timeout) not found.
  • if checking for absence of element must always wait until timeout.
  • cannot be customised other than global timeout.

This list is gathered from observations and reading bug reports and cursory reading of selenium source code.

Let me tell you one thing : <Always use explicit wait. Forget that implicit wait exists>                                              --Naveen Khunteta

2. Explicit Wait

Explicit wait is of two types:

a) WebDriverWait (Class) : 

b) FluentWait (Class)

Both are classes and implements Wait interface.

WebDriverWait class is an extension of FluentWait class. It doesn’t have its own methods.

  • Explicit wait waits for a certain condition till specific element is not loaded.
  • Its implementation is given by WebDriverWait Class in selenium with some expected conditions.
  • This can be useful when certain elements on the webpage are not available immediately and need some time to load for e.g when you click on some submit button after you fill some registration form, then it takes some time in processing and displaying the data on UI.
  • Selenium has its predefined conditions provided in ExpectedConditions class.
  • Below is the syntax to define explicit wait and the expected conditions to be selected based on our needs:

Expected Conditions

So do I need to use Explicit Wait? Answer is YESSSS..

  • documented and defined behaviour.
  • runs in the local part of selenium (in the language of your code).
  • works on any condition you can think of.
  • returns either success or timeout error.
  • can define absence of element as success condition.
  • can customise delay between retries and exceptions to ignore.

Fluent Wait:

As per Official Selenium API Documentation, FluentWait is:

An implementation of the Wait interface that may have its timeout and polling interval configured on the fly.

Each FluentWait instance defines the maximum amount of time to wait for a condition, as well as the frequency with which to check the condition. Furthermore, the user may configure the wait to ignore specific types of exceptions whilst waiting, such as NoSuchElementExceptions when searching for an element on the page.

  • FluentWait is used when we can define the maximum time to wait for a condition, It also defines the frequency with which WebDriver will check if the condition appears before throwing the “ElementNotVisibleException”.
  • We can configure the wait to ignore specific types of exceptions while waiting, such as NoSuchElementException when searching for an element on the page.
  • The fluent wait is a class and an implementation of Wait interface and also parent class of WebDriverWait.
  • We can customise the below apply method to give any conditions based on our specifications.

Syntax:

Let’s below code snippet :

Code for Fluent Wait

package com.example.automation;

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.support.ui.*;
import java.time.Duration;
import java.util.function.Function;

/**
 * @author Mandeep Kaur
 * @Date 2 May,2020
 */
public class SeleniumConfig {
    public static void main(String[] args) {
        String path = System.getProperty("user.dir");
        System.setProperty("webdriver.chrome.silentOutput", "true");
        System.setProperty("webdriver.chrome.driver", path + "/chromedriver");
        WebDriver driver = new ChromeDriver();
        driver.get("https://www.facebook.com/");
        // Create object of WebDriverWait class

        Wait wait = new FluentWait(driver)
                //Wait for the condition
                .withTimeout(Duration.ofSeconds(10))
                //checking for its presenceonce every 5 seconds.
                .pollingEvery(Duration.ofSeconds(5))
                //Which will ignore the Exception
                .ignoring(Exception.class);

        WebElement element = wait.until(new Function<WebDriver, WebElement>() {
            @Override
            public WebElement apply(WebDriver driver) {
                return driver.findElement(By.name("lastname"));

            }
        });
        element.sendKeys("Martin");
    }
}

Explanation:

To put it simply, Fluent Wait looks for a web element repeatedly at regular intervals until timeout happens or until the object is found.

  • The above code defines time out value as 10 seconds and polling frequency as 5 seconds that means for every 5 seconds it keeps on checking for element.
  • It directs WebDriver to wait for a maximum of 10 seconds to verify a specific condition. If the condition occurs during those 10 seconds, it will perform the next step in the test script. If not, it will throw an “ElementNotVisibleException”.

So when should I use FluentWait?

  • When you do not see suitable expected wait condition in explicit wait.
  • To handle dynamic AJAX web elements with polling mechansim
  • You need to do more than just waiting along with Polling Mechanism, IgnoredException and when you want to create your own custom wait condition (in apply method) for non WebDriver use cases as well.
So can I use FluentWait features like, polling interval, ignoreAll with WebDriverWait? 
Ans
: Yes, of course you can do that, as I have explained earlier WebDriverWait is child class of FluentWait, so it has access on all parent class public methods.

Refer this WebDriver API on GIT:

https://github.com/SeleniumHQ/selenium/blob/master/java/client/src/org/openqa/selenium/support/ui/FluentWait.java

Final Conclusion:

a. Wait is an Interface in Selenium and having only one method declaration:

public interface Wait {

until(Function<? super F, T> isTrue);

}

b. FluentWait is a class which is implementing Wait Interface, it’s having its own methods shown above and overridden until() method from the wait Interface. 

public class FluentWait implements Wait<T> { }

c. WebDriverWait is extending FluentWait class but has no methods init except one overridden method, that is: timeoutException(){}.

WebDriverWait can use all the methods of FluentWait class – pollingEvery(), withMessage(), ignoreAll etc..

FluentWait can be used for both WebDriver and non WebDriver use cases. It just needs a condition – waitForCondition.

3. Concept of Thread.sleep()

  • It is a static wait and execution of the scripts will be on hold till specified time configured in the function.
  • Thread is a class in JAVA and sleep is static method.
  • sleep() methods accept duration in milliseconds. ( 1 s= 1000 ms).
  • It throws  IllegalArgumentException – if the value of ms is negative.
  • sleep() throws a checked exception which we must either throw or handle it using try catch like done below
  • Syntax:

try{
Thread.sleep(5000);
}
catch(InterruptedException e){
}

Note: it’s never a good idea to use thread.sleep () as unlike dynamic waits it will wait for the entire time configured in the function till the element gets loaded.

4. PageLoadTimeOut & SetScriptTimeOut property

PageLoadTimeOut

  • PageLoadTimeOut is focused on the time a webpage needs to be loaded – the page load timeout limits the time that the script allows for a web page to be displayed.
  • If the page loads within the time, then the script continues. If the page does not load within the timeout the script will be stopped by a TimeoutException.
  • The timeout is set at the driver level. After creating the driver instance with the appropriate driver capabilities.
  • Syntax :

   driver.manage().timeouts().pageLoadTimeout(2, TimeUnit.SECONDS);

SetScriptTimeOut

  • From WebDriver documentation: setScriptTimeout(long time, java.util.concurrent.TimeUnit unit) sets the amount of time to wait for an asynchronous script to finish execution before throwing an error.
  • This works only for Async scripts (executeAsyncScript: calls which takes some time to respond back)
  • Syntax:

driver.manage().timeouts().setScriptTimeout(1, TimeUnit.SECONDS);

5. Conclusion:

In this article , we learnt about the various waits in selenium WebDriver.

Selenium While running a script, you are getting “NoSuchElementException”. But you have taken the correct locator(ID, XPATh or CSS). Still you are facing the same issue. What might be the reason? Cognizant Bhubaneswar, India I answered like this. I said that particular web element may be present in a frame. So if you are not switching to that frame before doing any action on that web element then you will get “NoSuchElementException” even if you have taken the correct locator.  Yes

Selenium Selenium Automation Testing Real world Interview Question and Answer

 

Question: – How to switch from frame to main window? With syntax.

Answer: – We can give frame name, id, index and WebElement locator for identification

Syntax

driver.switchTo().frames();                  // Switch to window to frame

driver.switchTo().defaultContent();  // Switch to Frame to window

If we know the total number of frames in the web page, then we can use “index”. Index values help to easily switch between frames. Index will start from Zero i.e. if web page has only one frame then its index will be Zero.

         If we don’t know the number of frames the we can use “findElementBytabname()” method

        Syntax: –

                                      try

{

driver.switchTo().frame(indexnumber);

}

                                      catch(NoSuchFrameException e)

{

System.out.println(e.getMessage());

}

We have use try and catch if now frame will not available this throw exception  .      .  .          NoSuchFrameException()

Use name as locater to find frame

Syntax: –

                  try

{

driver.switchTo().frame(“frameName”);

}

                    catch(NoSuchFrameException e)

{

System.out.println(e.getMessage());

}

Use WebElement for switching frame

                Syntax: –

               try

{

WebElement button=driver.findElement(By.xpath(“”));

driver.switchTo().frame(button);

}

              catch (NoSuchFrameException e)

{

System.out.println(e.getMessage());

}

Question: -What is difference between (page object model) pom and pagefactory?

Answer: –

Page Object Model (POM)

Page Factory

POM is a Design pattern which segregate selenium code based on pages.

Ex: Create a separate java class for Login page , one more class for Home Page etc.

Advanced concept ( POM + new features )or

1. Elements are identified using @FindBy or @FindBys Annotation

2. Initialism all the elements declared in Point#1 at a time.

( in POM, initialization happens on the fly )

PageFactory.initElements(driver,this);

A Page Object Model is a way of representing an application in a test framework. For every ‘page’ in the application you create a Page Object to reference the ‘page’.

A Page Factory is one way of implementing a Page Object Model. In order to support the Page Object pattern, WebDriver’s support library contains a factory class.

 

Question: – What are challenges that you faced while automating test cases?

Answer: – Two types of challenges tester have to face one is technical and another is non-technical.

Technically

There are four common issues in test automation that are: –

Wait time issues.

Ifream issues

Pop-up issues

Issues in locating deeply nested elements.

Note: – Depend on which tool you are going to use/ using, the ways to solve might different.

Non-Technically

Real Challenges comes in front of tester when client changes his requirement.

Time pressure and Deadlines.

Testing complete application.

Automate everything

Network unavailability

Understanding company, client, and end-user expectations.

Deciding when can testing should stop and how much testing coverage is enough.

Find masked bugs.

Receiving Management approval.

Selecting and using the appropriate tools.

Recognising a starting strategy.

Making realistic expectations for automation.

 

Question: -There is a submit button in page it has id property. By using “id” we got “element not found expectation”, how will you handle this situation? What might be the problem in this case?

Answer: – In this situation, there are mainly two reasons that are:-

ID is not matching

ID is changing each time when load the page.

So to handle this situation instead of using find element by Id, we can use find element by Xpath.

Question: – If submit button contain in one of 3 frames in page, how will you handle this case?

Answer: – We can handle this problem by using SwitchTo() command.

 

Question: – If element is loaded by taking much time how to handle this situation in selenium.

Answer: – Using Wait can handle this situation in selenium.

 

Question: – What is the problem with Thread.Sleep in code?

Answer: – Theard.sleep() introduces a definite wait(that is fixed periods of inactivity) no matter what happens, which will slow down our test, and if you are using CI(Continuous integration) generally result take much time if we use it all over the place.

Secondly most people who use it end up doing so because they don’t understand a problem so it’s quick and easy to just throw in an arbitrary wait rather than trying to understand the problem and fix it.

For Example: – If we do an AJAX action and then have to wait for an element to appear, the correct thing to do would be to scan for the element until it appears, the correct thing to do would be to scan for the element until it appears and then carry on, but this is harder to code than to just throw in a 30 second wait so people use a Thread.seelp() instead.

Now the problem is that this means you don’t really know why the test has failed if the element is not picked up after your 30 second time out, is it because the element didn’t appear at all, or is it because the AJAX call took longer than normal to return?

If you had some code that scanned for the element you could stick in a much longer timeout secure in the knowledge that you are not slowing your test down, and also secure in the knowledge that when it fails you can be sure that it is because the element didn’t return.

I’m sure people will argue that it is easier to use Thread.sleep() and the difference in results as described above is not that great, but when you have 200 scripts getting run in CI and each one has about 5 Thread.sleeep() calls you’ll see how much pain just throwing in a Thread.sleep() can cause.

 

Question: – What is the concept of selenium grid?

Answer: – Selenium-Grid allows you run your tests on different machines against different browsers in parallel. That is, running multiple tests at the same time against different machines running different browsers and operating systems. Essentially, Selenium-Grid support distributed test execution. It allows for running your tests in a distributed test execution environment.

 

Question: – When we execute test cases in grid where results will be stored in node or hub?

Answer: – Selenium and Grid is installed on hub, and they are not installed on nodes. Nodes contain only he jar files. So the result will be stored in hub

 

Question: – Difference b/w quit and close?

Answer: – close() command closes the Browser window which is in focus. If there are more than one Browser window opened by the Selenium Automation, then the close( ) command will only close the Browser window which is having focus at that time. It won’t close the remaining Browser windows.

Whereas quit() command is used to close the focus browser basically quit() command shut down the WebDrivers instance and close all the Browser window which is having focus at that time.

If Selenium Automation opens only single Browser window the close() and quit() commands work in the similar way. But when there are more than one Browser windows opened by the Selenium Automation they work differently.

 

Question: – Manually you opened a Firefox browser window with Gmail login, now with selenium you opened a Firefox browser window with Facebook login, what happens when we use quit method? Will it closes all windows including Gmail one?

Answer: – quit() command is used to close the focus browser basically quit() command shut down the WebDrivers instance and close all the Browser window which is having focus at that time.

So it will close only Firefox browser window with Facebook login.

 

Question: – What all annotations used in TestNG ?

Answer: – Total 15 annotations are used in TestNG

@BeforeSuite: – The annotated method will be run only once before all tests in this suite have run.@AfterSuite: – The annotated method will be run only once after all tests in this suite have run.@BeforeClass: – The annotated method will be run only once before the first test method in the current class is invoked.@AfterClass: – The annotated method will be run only once after all the test methods in the current class have run.@BeforeTest: – The annotated method will be run before any test method belonging to the classes inside the tag is run.@AfterTest: – The annotated method will be run after all the test methods belonging to the classes inside the tag have run.@BeforeGroups: – The list of groups that this configuration method will run before. This method is guaranteed to run shortly before the first test method that belongs to any of these groups is invoked.@AfterGroups: – The list of groups that this configuration method will run after. This method is guaranteed to run shortly after the last test method that belongs to any of these groups is invoked.@BeforeMethod: – The annotated method will be run before each test method.@AfterMethod: – The annotated method will be run after each test method.@DataProvider: – Marks a method as supplying data for a test method. The annotated method must return an Object [ ][ ], where each Object[ ] can be assigned the parameter list of the test method. The @Test method that wants to receive data from this DataProvider needs to use a dataProvider name equals to the name of this annotation.@Factory: – Marks a method as a factory that returns objects that will be used by TestNG as Test classes. The method must return Object[ ].@Listeners: – Defines listeners on a test class.@Parameters: – Describes how to pass parameters to a @Test method.@Test: – Marks a class or a method as a part of the test.

 

Question: – If we want to do DataDriven with TestNG, which annotations required?

Answer: – TestNG @DataProvider Annotation is required for DataDriven with TestNG. @DataProvider Annotation of TestNG framework provides us a facility of storing and preparing data set in method. Task of @DataProvider annotated method is supplying data for a test method. Means you can configure data set in that method and then use that data In your test method. @DataProvider annotated method must return an Object[][] with data.

 

Question: – Is it possible to pass test data through testng.xml file, if yes how?

Answer: – Yes it is possible to pass test data through XML file by using @Parameters annotations

To do so, you will need to

Create an XML file which will store the parametersIn the test, add annotation @Parameters

XML File



Selenium Scripting

@Test

@Parameters({“author”,”searchKey”})

public void testParameterWithXML(@Optional(“ABC”)String author,String searchKey)throws InterruptedException{}

Note: -There are mainly two ways through which we can provide parameter values to test-methods: One is through testng.xml XML configuration file and through DataProviders.

Question: – How to run specific kind of Test cases using TestNG?

Answer: – Three ways we can run Test Cases using TestNG

On an existing testng.xml.On a synthetic testng.xml, created entirely from Java.By directly setting the test classes.

 

Question: – How to prioritize test cases in TestNG?

Answer: – In TestNG “Priority” is used to schedule the test cases.at is we can execute Test case in order.  In order to achive, we use need to add annotation as @Test(priority=??). The default value will be zero for priority.

If you don’t mention the priority, it will take all the test cases as “priority=0” and execute.

If we define priority as “priority=”, these test cases will get executed only when all the test cases which don’t have any priority as the default priority will be set to “priority=0”

 

Question: – What are all interfaces available in selenium?

Answer: –

InterfaceDescriptionAlertCapabilitiesDescribes a series of key/value pairs that encapsulate aspect of a browserContextAwareSome implementations of WebDriver, notably those that support native testing, need the ability to switch between the native and web-based contexts.HasCapabilitiesUsed by classes to indicate that they can describe the capabilities they possess.JavascriptExecutorIndicates that a driver can execute JavaScript, providing access to the mechanism to do so.OutputTypeDefines the output type for a screenshot.RotatableRepresents rotation of the browser view for orientation – sensitive devices.SearchContextTakeScreenshotIndicates a driver that can capture a screenshot and store it in different ways.WebDriverThe main interface to use for testing, which represents an idealised web browserWebDriver.ImeHandlerWebDriver.OptionsAn Interface for managing stuff you would do in a browser menuWebDriver.TargetLocatorUsed to locate a given frame or window.WebDriver.TimeoutsAn interface for managing timeout behaviour for WebDriver instanceWebDriver.WindowWebElementRepersents an HTML element.

 

Question: – Action is class or interface?

Answer: – Action is an interface.

Use to perform Advanced User Interactions, like drag and drop, keyboard events; selenium came up with Action and Actions interface under a comprehensive API, named as Advanced User Interaction which facilitates user actions to be performed on an application. Thus users can use this API to simulate usage of keyboard or mouse events.

Example:-

To double-click a control we have DoubleClick(), method of Actions Class.

To Send keyboard actions, we have SendKeys() ,method.(Equivalent to WebElement.sendKey(…))

Clicking the mouse button that brings up the contextual menu.we can use “ContextClick()”, method.

Package:-

import org.openqa.selenium.interactions.Actions;
import org.openqa.selenium.interactions.Action;

Syntax:-

Actions oAction=new Actions(selenium);

oAction.contextClick(element).perform();

 

Question: – Why we using TestNG? What are benefits we get using TestNG? Can we execute test cases in order without using TestNG?

Answer: – WHY We Using TestNG

TestNG is a testing framework inspired from JUnit and NUnit but introducing some new functionality that make it more powerful and easier to use, such as:

Run your tests in arbitrarily big thread pools with various policies available (all methods in their own thread, one thread per test class, etc…).

Test that your code is multithread safe.

Flexible test configuration.

Support for data-driven testing (with @DataProvider).

Support for parameters.

Powerful execution model (no more TestSuite).

Supported by a variety of tools and plug-ins (Eclipse, IDEA, Maven, etc…).

Embeds BeanShell for further flexibility.

Default JDK functions for runtime and logging (no dependencies).

Dependent methods for application server testing.

TestNG is designed to cover all categories of tests:  unit, functional, end-to-end, integration, etc…

Advantages of TestNG

TestNG allows us to execute of test cases based on group.

TestNG annotations are easy to understand.

Parallel execution of selenium test cases is possible in TestNG.

Three kinds of report generated.

Order of execution can be change using TestNG

Failed test cases can be executed.

Without having main function we can execute the test method.

An xml file can be execution order and we can skip the execution of particular test case.

Can we execute test cases in order without using TestNG

 Yes, we execute test cases in order without using TestNG with the help of Junit

 

Question: – Explain polymorphism in java.

Answer: – Polymorphism means ‘many forms’. In OOP, polymorphism means a type can point to different object at different time. In other words, the actual object to which a reference type refers can be determined at runtime.

In Java, polymorphism is based on inheritance and overriding.

Polymorphism is a robust feature of OOP. It increases the reusability, flexibility and extensibility of code.

 

Question: -There are two methods in same class with same name with different arguments and different access modifiers like

 public void m1(int a){}

 private void m1(string b){}

 Is it overloading or not?

Answer: – Overloading allows different methods to have same name, but different signatures where signature can differ by number of input/output parameters or type of input/output parameters or both.

So yes this is overloading.

 

Question: – What are types of inheritance in java?

Answer: -Single Inheritance, Multi-Level Inheritance and Hierarchical Inheritance.

 

Question: – Is multiple inheritance is possible in java? Reasons?

Answer: – To reduce the complexity and simplify the language, multiple inheritance is not supported in java.

Consider a scenario where A, B and C are three classes. The C class inherits A and B classes. If A and B classes have same method and you call it from child class object, there will be ambiguity to call method of A or B class.

Since compile time errors are better than runtime errors, java renders compile time error if you inherit 2 classes. So whether you have same method or different, there will be compile time error now.

 

Question: – Is multilevel inheritance is possible in java? Give reason.

Answer: – A class can implement multiple interfaces. Object class is not an example of multiple inheritance. May be you misinterpreted the question. The answer is Java supports multi-level inheritance but not multiple inheritance.

 

Question: – There are 10 pages in same window; an image is present in any page out of ten pages in same window. How will you validate this scenario?

Answer: – Get the total numbers of frames on a webpage base on that have a for loop and switchTo() all frame one by one and check if image is present then come out of  that frame and again switch to next frame, continue this till you get image then break the loop.

Question: – How to check image is loaded correctly or not in page?

Answer:
WebElement image1 = driver.findElement(By.xpath(“//div[contains(@class,’global-header__brand’)]”));

Boolean imageLoaded1 = (Boolean) ((JavascriptExecutor)driver).executeScript(“return arguments[0].complete && typeof arguments[0].naturalWidth != “undefined” && arguments[0].naturalWidth > 0″, image1);

if (!imageLoaded1)

{

System.out.println(“1. Image is not present”);

}

else

{

System.out.println(“1. Got it”);

}

 

Question: – What is the purpose of Sikuli?

Answer: -Sikuli automates anything you see on screen using the image recognition method to identify GUI elements. Sikuli script allows users to automate GUI interaction by using screenshots.

 

Question: – Is it possible to compare two images with Sikuli?

Answer: – Yes

 

Question: – How to check webpage is fully loaded or not using Selenium?

Answer: – This situation can be solved by using JavaScript executors.

IWait wait = new OpenQA.Selenium.Support.UI.WebDriverWait(driver, TimeSpan.FromSeconds(30.00));

wait.Until(driver1 => ((IJavaScriptExecutor)driver).ExecuteScript(“return document.readyState”).Equals(“complete”));

 

Question: – Write a code for DB connection.

Answer: – Creating SQL & MySQL Connections:

package util;

import java.sql.*;

import java.util.ArrayList;

import java.util.List;

public class DbManager

{

private static Connection con = null;

private static Connection conn = null;

// Database connection for SQL Server

public static void setDbConnection() throws SQLException, ClassNotFoundException, AddressException, MessagingException

{

try{

Class.forName(TestConfig.driver);

con =   DriverManager.getConnection(dbConnectionUrl, dbUserName, dbPassword);

if(!con.isClosed())

System.out.println(“Successfully connected to SQL server”);

}catch(Exception e){

System.err.println(“Exception: ” + e.getMessage());

}       }

public static void setMysqlDbConnection() throws SQLException, ClassNotFoundException, AddressException, MessagingException

{

try

{

Class.forName (TestConfig.mysqldriver).newInstance ();

conn = DriverManager.getConnection (mysqlurl, mysqluserName, mysqlpassword);

if(!conn.isClosed())

System.out.println(“Successfully connected to MySQL server”);

}

catch (Exception e)

{

System.err.println (“Cannot connect to database server”);

}

}

// Query list for SQL

public static List getQuery(String query) throws SQLException

{

Statement St = con.createStatement();

ResultSet rs = St.executeQuery(query);

List values = new ArrayList();

while(rs.next()){

values.add(rs.getString(1));

}

return values;

}

// Query list for MySQL

public static List getMysqlQuery(String query) throws SQLException

{

Statement St = conn.createStatement();

ResultSet rs = St.executeQuery(query);

List values1 = new ArrayList();

while(rs.next()){

values1.add(rs.getString(1));

}

return values1;

}

 

Question: – How do you handle exception handling in selenium?

Answer: – Same Try Catch like used in java.

 

Question: – Explain run time and compile time polymorphism.

Answer: – Overloading is compile time polymorphism where more than one methods share the same name with different parameters or signature and different return type.

Overriding is run time polymorphism having same method with same parameters or signature, but associated in a class & its subclass.

Compile time PolymorphismRun time PolymorphismIn Compile time Polymorphism, call is resolved by the compiler.In Run time Polymorphism, call is not resolved by the compiler.It is also known as Static binding, Early binding and overloading as well.It is also known as Dynamic binding, Late binding and overriding as well.Overloading is compile time polymorphism where more than one methods share the same name with different parameters or signature and different return type.Overriding is run time polymorphism having same method with same parameters or signature, but associated in a class & its subclass.It is achieved by function overloading and operator overloading.It is achieved by virtual functions and pointers.It provides fast execution because known early at compile time.It provides slow execution as compare to early binding because it is known at runtime

 

Question: – Write a code for multiple handling windows?

Answer: –

public void test() throws Exception {
// Opening site
driver.findElement(By.xpath(“//img[@alt=’SeleniumMasterLogo’]”)).click();
// Storing parent window reference into a String Variable
String Parent_Window = driver.getWindowHandle();
// Switching from parent window to child window
for (String Child_Window : driver.getWindowHandles())
{
driver.switchTo().window(Child_Window);
// Performing actions on child window
driver.findElement(By.id(“dropdown_txt”)).click();
List  dropdownitems=driver.findElements(By.xpath(“//div[@id=’DropDownitems’]//div”));
int dropdownitems_Size=dropdownitems.size();
System.out.println(“Dropdown item size is:”+dropdownitems_Size);
((WebElement) dropdownitems.get(1)).click();
driver.findElement(By.xpath(“//*[@id=’anotherItemDiv’]”)).click();
}
//Switching back to Parent Window
driver.switchTo().window(Parent_Window);
//Performing some actions on Parent Window
driver.findElement(By.className(“btn_style”)).click();
}

 

Question: -How do you handle synchronization in selenium?

Answer: – By using wait we can handle synchronization in Selenium.

 

Question: – Why do we need Software Testing Metrics?

Answer: – Metrics provide insight into the project’s status in relation to predefined goals.    It is important to measure the efficiency and effectiveness of the Test processes. Without metrics, how would you know that everything is right OR something needs your attention!

Helps in decision-making for next phase of activities, process or technology change.

Easy for management to digest one number and drill down, if required.

Different Metric(s) trends act as monitor when the process is going out-of-control.

Evidence of the claim or prediction.

Help us judge how efficient the testing efforts are.

Make proactive and informed decisions

 

Question: – 7 Soft skills every ‘QA Tester’ needs:

Answer:

Know how to ask the right questions, and when to ask them

Know how to listen

Know how to focus on what business stakeholders care about … and forget the rest

Know how to play well with others: Take a developer to lunch

Know how to deal with bullies

Know how to manage your time effectively

Know how to trust your judgment — and your intuition

 

Question: – What is the most challenging situation you have had in your Testing experience?

Answer: – As you might have guessed, it depends on each tester’s experience. The challenge can be technical, process-oriented, people’s related, domain specific OR anything within your Testing experience. For me,

Testing a technically-challenging application such as social-connected applications, application involving multiple third-party interfaces, cloud-big data-IoT-Analytics-etc. applications.

Maintaining a balance between design/execution efficiency and defect detection. Improving the Test coverage. Sticking to agile principles.

Resources on unplanned leaves, some even abscond. Estimation gone wrong, requiring weekend & extended working hours. Rating discussions with unhappy employees.

A team of fresher’s with limited domain knowledge. Planning for knowledge transfer sessions. The thumb rule – be realistic & tell your genuine challenges!

 

Question: – What is Automation and Manual Testing?

Answer: –

Automation: Software testing method which uses automation software, tools and scripts to run tests that repeat predefined actions, matches the developed program’s probable and real results.

Manual: The process of manual software testing involves manually running the individual tests or tasks associated with a product without the aid of scripts or other tools, in order to identify bugs or other issues. During this process, the testing team will use the application from end-user perspective.

 

Question: – How generate user defined exceptions, write syntax?

throw new MyException(“Custom message”);

}

catch(MyException exp)

{

System.out.println(exp);     ‘

}

}

}

 

Question: – Difference between throw and throws keyword?

Answer: –

throwthrowsJava throw keyword is used to explicitly throw an exception.Java throws keyword is used to declare an exception.Checked exception cannot be propagated using throw only.Checked exception can be propagated with throws.Throw is followed by an instance.Throws is followed by class.Throw is used within the method.Throws is used with the method signature.You cannot throw multiple exceptions.You can declare multiple exceptions e.g.
public void method()throws IOException,SQLException.

Selenium Selenium Automation Testing Real world Interview Question and Answer

 

Question: – How to switch from frame to main window? With syntax.

Answer: – We can give frame name, id, index and WebElement locator for identification

Syntax

driver.switchTo().frames();                  // Switch to window to frame

driver.switchTo().defaultContent();  // Switch to Frame to window

If we know the total number of frames in the web page, then we can use “index”. Index values help to easily switch between frames. Index will start from Zero i.e. if web page has only one frame then its index will be Zero.

         If we don’t know the number of frames the we can use “findElementBytabname()” method

        Syntax: –

                                      try

{

driver.switchTo().frame(indexnumber);

}

                                      catch(NoSuchFrameException e)

{

System.out.println(e.getMessage());

}

We have use try and catch if now frame will not available this throw exception  .      .  .          NoSuchFrameException()

Use name as locater to find frame

Syntax: –

                  try

{

driver.switchTo().frame(“frameName”);

}

                    catch(NoSuchFrameException e)

{

System.out.println(e.getMessage());

}

Use WebElement for switching frame

                Syntax: –

               try

{

WebElement button=driver.findElement(By.xpath(“”));

driver.switchTo().frame(button);

}

              catch (NoSuchFrameException e)

{

System.out.println(e.getMessage());

}

Question: -What is difference between (page object model) pom and pagefactory?

Answer: –

Page Object Model (POM)

Page Factory

POM is a Design pattern which segregate selenium code based on pages.

Ex: Create a separate java class for Login page , one more class for Home Page etc.

Advanced concept ( POM + new features )or

1. Elements are identified using @FindBy or @FindBys Annotation

2. Initialism all the elements declared in Point#1 at a time.

( in POM, initialization happens on the fly )

PageFactory.initElements(driver,this);

A Page Object Model is a way of representing an application in a test framework. For every ‘page’ in the application you create a Page Object to reference the ‘page’.

A Page Factory is one way of implementing a Page Object Model. In order to support the Page Object pattern, WebDriver’s support library contains a factory class.

 

Question: – What are challenges that you faced while automating test cases?

Answer: – Two types of challenges tester have to face one is technical and another is non-technical.

Technically

There are four common issues in test automation that are: –

Wait time issues.

Ifream issues

Pop-up issues

Issues in locating deeply nested elements.

Note: – Depend on which tool you are going to use/ using, the ways to solve might different.

Non-Technically

Real Challenges comes in front of tester when client changes his requirement.

Time pressure and Deadlines.

Testing complete application.

Automate everything

Network unavailability

Understanding company, client, and end-user expectations.

Deciding when can testing should stop and how much testing coverage is enough.

Find masked bugs.

Receiving Management approval.

Selecting and using the appropriate tools.

Recognising a starting strategy.

Making realistic expectations for automation.

 

Question: -There is a submit button in page it has id property. By using “id” we got “element not found expectation”, how will you handle this situation? What might be the problem in this case?

Answer: – In this situation, there are mainly two reasons that are:-

ID is not matching

ID is changing each time when load the page.

So to handle this situation instead of using find element by Id, we can use find element by Xpath.

Question: – If submit button contain in one of 3 frames in page, how will you handle this case?

Answer: – We can handle this problem by using SwitchTo() command.

 

Question: – If element is loaded by taking much time how to handle this situation in selenium.

Answer: – Using Wait can handle this situation in selenium.

 

Question: – What is the problem with Thread.Sleep in code?

Answer: – Theard.sleep() introduces a definite wait(that is fixed periods of inactivity) no matter what happens, which will slow down our test, and if you are using CI(Continuous integration) generally result take much time if we use it all over the place.

Secondly most people who use it end up doing so because they don’t understand a problem so it’s quick and easy to just throw in an arbitrary wait rather than trying to understand the problem and fix it.

For Example: – If we do an AJAX action and then have to wait for an element to appear, the correct thing to do would be to scan for the element until it appears, the correct thing to do would be to scan for the element until it appears and then carry on, but this is harder to code than to just throw in a 30 second wait so people use a Thread.seelp() instead.

Now the problem is that this means you don’t really know why the test has failed if the element is not picked up after your 30 second time out, is it because the element didn’t appear at all, or is it because the AJAX call took longer than normal to return?

If you had some code that scanned for the element you could stick in a much longer timeout secure in the knowledge that you are not slowing your test down, and also secure in the knowledge that when it fails you can be sure that it is because the element didn’t return.

I’m sure people will argue that it is easier to use Thread.sleep() and the difference in results as described above is not that great, but when you have 200 scripts getting run in CI and each one has about 5 Thread.sleeep() calls you’ll see how much pain just throwing in a Thread.sleep() can cause.

 

Question: – What is the concept of selenium grid?

Answer: – Selenium-Grid allows you run your tests on different machines against different browsers in parallel. That is, running multiple tests at the same time against different machines running different browsers and operating systems. Essentially, Selenium-Grid support distributed test execution. It allows for running your tests in a distributed test execution environment.

 

Question: – When we execute test cases in grid where results will be stored in node or hub?

Answer: – Selenium and Grid is installed on hub, and they are not installed on nodes. Nodes contain only he jar files. So the result will be stored in hub

 

Question: – Difference b/w quit and close?

Answer: – close() command closes the Browser window which is in focus. If there are more than one Browser window opened by the Selenium Automation, then the close( ) command will only close the Browser window which is having focus at that time. It won’t close the remaining Browser windows.

Whereas quit() command is used to close the focus browser basically quit() command shut down the WebDrivers instance and close all the Browser window which is having focus at that time.

If Selenium Automation opens only single Browser window the close() and quit() commands work in the similar way. But when there are more than one Browser windows opened by the Selenium Automation they work differently.

 

Question: – Manually you opened a Firefox browser window with Gmail login, now with selenium you opened a Firefox browser window with Facebook login, what happens when we use quit method? Will it closes all windows including Gmail one?

Answer: – quit() command is used to close the focus browser basically quit() command shut down the WebDrivers instance and close all the Browser window which is having focus at that time.

So it will close only Firefox browser window with Facebook login.

 

Question: – What all annotations used in TestNG ?

Answer: – Total 15 annotations are used in TestNG

@BeforeSuite: – The annotated method will be run only once before all tests in this suite have run.@AfterSuite: – The annotated method will be run only once after all tests in this suite have run.@BeforeClass: – The annotated method will be run only once before the first test method in the current class is invoked.@AfterClass: – The annotated method will be run only once after all the test methods in the current class have run.@BeforeTest: – The annotated method will be run before any test method belonging to the classes inside the tag is run.@AfterTest: – The annotated method will be run after all the test methods belonging to the classes inside the tag have run.@BeforeGroups: – The list of groups that this configuration method will run before. This method is guaranteed to run shortly before the first test method that belongs to any of these groups is invoked.@AfterGroups: – The list of groups that this configuration method will run after. This method is guaranteed to run shortly after the last test method that belongs to any of these groups is invoked.@BeforeMethod: – The annotated method will be run before each test method.@AfterMethod: – The annotated method will be run after each test method.@DataProvider: – Marks a method as supplying data for a test method. The annotated method must return an Object [ ][ ], where each Object[ ] can be assigned the parameter list of the test method. The @Test method that wants to receive data from this DataProvider needs to use a dataProvider name equals to the name of this annotation.@Factory: – Marks a method as a factory that returns objects that will be used by TestNG as Test classes. The method must return Object[ ].@Listeners: – Defines listeners on a test class.@Parameters: – Describes how to pass parameters to a @Test method.@Test: – Marks a class or a method as a part of the test.

 

Question: – If we want to do DataDriven with TestNG, which annotations required?

Answer: – TestNG @DataProvider Annotation is required for DataDriven with TestNG. @DataProvider Annotation of TestNG framework provides us a facility of storing and preparing data set in method. Task of @DataProvider annotated method is supplying data for a test method. Means you can configure data set in that method and then use that data In your test method. @DataProvider annotated method must return an Object[][] with data.

 

Question: – Is it possible to pass test data through testng.xml file, if yes how?

Answer: – Yes it is possible to pass test data through XML file by using @Parameters annotations

To do so, you will need to

Create an XML file which will store the parametersIn the test, add annotation @Parameters

XML File



Selenium Scripting

@Test

@Parameters({“author”,”searchKey”})

public void testParameterWithXML(@Optional(“ABC”)String author,String searchKey)throws InterruptedException{}

Note: -There are mainly two ways through which we can provide parameter values to test-methods: One is through testng.xml XML configuration file and through DataProviders.

Question: – How to run specific kind of Test cases using TestNG?

Answer: – Three ways we can run Test Cases using TestNG

On an existing testng.xml.On a synthetic testng.xml, created entirely from Java.By directly setting the test classes.

 

Question: – How to prioritize test cases in TestNG?

Answer: – In TestNG “Priority” is used to schedule the test cases.at is we can execute Test case in order.  In order to achive, we use need to add annotation as @Test(priority=??). The default value will be zero for priority.

If you don’t mention the priority, it will take all the test cases as “priority=0” and execute.

If we define priority as “priority=”, these test cases will get executed only when all the test cases which don’t have any priority as the default priority will be set to “priority=0”

 

Question: – What are all interfaces available in selenium?

Answer: –

InterfaceDescriptionAlertCapabilitiesDescribes a series of key/value pairs that encapsulate aspect of a browserContextAwareSome implementations of WebDriver, notably those that support native testing, need the ability to switch between the native and web-based contexts.HasCapabilitiesUsed by classes to indicate that they can describe the capabilities they possess.JavascriptExecutorIndicates that a driver can execute JavaScript, providing access to the mechanism to do so.OutputTypeDefines the output type for a screenshot.RotatableRepresents rotation of the browser view for orientation – sensitive devices.SearchContextTakeScreenshotIndicates a driver that can capture a screenshot and store it in different ways.WebDriverThe main interface to use for testing, which represents an idealised web browserWebDriver.ImeHandlerWebDriver.OptionsAn Interface for managing stuff you would do in a browser menuWebDriver.TargetLocatorUsed to locate a given frame or window.WebDriver.TimeoutsAn interface for managing timeout behaviour for WebDriver instanceWebDriver.WindowWebElementRepersents an HTML element.

 

Question: – Action is class or interface?

Answer: – Action is an interface.

Use to perform Advanced User Interactions, like drag and drop, keyboard events; selenium came up with Action and Actions interface under a comprehensive API, named as Advanced User Interaction which facilitates user actions to be performed on an application. Thus users can use this API to simulate usage of keyboard or mouse events.

Example:-

To double-click a control we have DoubleClick(), method of Actions Class.

To Send keyboard actions, we have SendKeys() ,method.(Equivalent to WebElement.sendKey(…))

Clicking the mouse button that brings up the contextual menu.we can use “ContextClick()”, method.

Package:-

import org.openqa.selenium.interactions.Actions;
import org.openqa.selenium.interactions.Action;

Syntax:-

Actions oAction=new Actions(selenium);

oAction.contextClick(element).perform();

 

Question: – Why we using TestNG? What are benefits we get using TestNG? Can we execute test cases in order without using TestNG?

Answer: – WHY We Using TestNG

TestNG is a testing framework inspired from JUnit and NUnit but introducing some new functionality that make it more powerful and easier to use, such as:

Run your tests in arbitrarily big thread pools with various policies available (all methods in their own thread, one thread per test class, etc…).

Test that your code is multithread safe.

Flexible test configuration.

Support for data-driven testing (with @DataProvider).

Support for parameters.

Powerful execution model (no more TestSuite).

Supported by a variety of tools and plug-ins (Eclipse, IDEA, Maven, etc…).

Embeds BeanShell for further flexibility.

Default JDK functions for runtime and logging (no dependencies).

Dependent methods for application server testing.

TestNG is designed to cover all categories of tests:  unit, functional, end-to-end, integration, etc…

Advantages of TestNG

TestNG allows us to execute of test cases based on group.

TestNG annotations are easy to understand.

Parallel execution of selenium test cases is possible in TestNG.

Three kinds of report generated.

Order of execution can be change using TestNG

Failed test cases can be executed.

Without having main function we can execute the test method.

An xml file can be execution order and we can skip the execution of particular test case.

Can we execute test cases in order without using TestNG

 Yes, we execute test cases in order without using TestNG with the help of Junit

 

Question: – Explain polymorphism in java.

Answer: – Polymorphism means ‘many forms’. In OOP, polymorphism means a type can point to different object at different time. In other words, the actual object to which a reference type refers can be determined at runtime.

In Java, polymorphism is based on inheritance and overriding.

Polymorphism is a robust feature of OOP. It increases the reusability, flexibility and extensibility of code.

 

Question: -There are two methods in same class with same name with different arguments and different access modifiers like

 public void m1(int a){}

 private void m1(string b){}

 Is it overloading or not?

Answer: – Overloading allows different methods to have same name, but different signatures where signature can differ by number of input/output parameters or type of input/output parameters or both.

So yes this is overloading.

 

Question: – What are types of inheritance in java?

Answer: -Single Inheritance, Multi-Level Inheritance and Hierarchical Inheritance.

 

Question: – Is multiple inheritance is possible in java? Reasons?

Answer: – To reduce the complexity and simplify the language, multiple inheritance is not supported in java.

Consider a scenario where A, B and C are three classes. The C class inherits A and B classes. If A and B classes have same method and you call it from child class object, there will be ambiguity to call method of A or B class.

Since compile time errors are better than runtime errors, java renders compile time error if you inherit 2 classes. So whether you have same method or different, there will be compile time error now.

 

Question: – Is multilevel inheritance is possible in java? Give reason.

Answer: – A class can implement multiple interfaces. Object class is not an example of multiple inheritance. May be you misinterpreted the question. The answer is Java supports multi-level inheritance but not multiple inheritance.

 

Question: – There are 10 pages in same window; an image is present in any page out of ten pages in same window. How will you validate this scenario?

Answer: – Get the total numbers of frames on a webpage base on that have a for loop and switchTo() all frame one by one and check if image is present then come out of  that frame and again switch to next frame, continue this till you get image then break the loop.

Question: – How to check image is loaded correctly or not in page?

Answer:
WebElement image1 = driver.findElement(By.xpath(“//div[contains(@class,’global-header__brand’)]”));

Boolean imageLoaded1 = (Boolean) ((JavascriptExecutor)driver).executeScript(“return arguments[0].complete && typeof arguments[0].naturalWidth != “undefined” && arguments[0].naturalWidth > 0″, image1);

if (!imageLoaded1)

{

System.out.println(“1. Image is not present”);

}

else

{

System.out.println(“1. Got it”);

}

 

Question: – What is the purpose of Sikuli?

Answer: -Sikuli automates anything you see on screen using the image recognition method to identify GUI elements. Sikuli script allows users to automate GUI interaction by using screenshots.

 

Question: – Is it possible to compare two images with Sikuli?

Answer: – Yes

 

Question: – How to check webpage is fully loaded or not using Selenium?

Answer: – This situation can be solved by using JavaScript executors.

IWait wait = new OpenQA.Selenium.Support.UI.WebDriverWait(driver, TimeSpan.FromSeconds(30.00));

wait.Until(driver1 => ((IJavaScriptExecutor)driver).ExecuteScript(“return document.readyState”).Equals(“complete”));

 

Question: – Write a code for DB connection.

Answer: – Creating SQL & MySQL Connections:

package util;

import java.sql.*;

import java.util.ArrayList;

import java.util.List;

public class DbManager

{

private static Connection con = null;

private static Connection conn = null;

// Database connection for SQL Server

public static void setDbConnection() throws SQLException, ClassNotFoundException, AddressException, MessagingException

{

try{

Class.forName(TestConfig.driver);

con =   DriverManager.getConnection(dbConnectionUrl, dbUserName, dbPassword);

if(!con.isClosed())

System.out.println(“Successfully connected to SQL server”);

}catch(Exception e){

System.err.println(“Exception: ” + e.getMessage());

}       }

public static void setMysqlDbConnection() throws SQLException, ClassNotFoundException, AddressException, MessagingException

{

try

{

Class.forName (TestConfig.mysqldriver).newInstance ();

conn = DriverManager.getConnection (mysqlurl, mysqluserName, mysqlpassword);

if(!conn.isClosed())

System.out.println(“Successfully connected to MySQL server”);

}

catch (Exception e)

{

System.err.println (“Cannot connect to database server”);

}

}

// Query list for SQL

public static List getQuery(String query) throws SQLException

{

Statement St = con.createStatement();

ResultSet rs = St.executeQuery(query);

List values = new ArrayList();

while(rs.next()){

values.add(rs.getString(1));

}

return values;

}

// Query list for MySQL

public static List getMysqlQuery(String query) throws SQLException

{

Statement St = conn.createStatement();

ResultSet rs = St.executeQuery(query);

List values1 = new ArrayList();

while(rs.next()){

values1.add(rs.getString(1));

}

return values1;

}

 

Question: – How do you handle exception handling in selenium?

Answer: – Same Try Catch like used in java.

 

Question: – Explain run time and compile time polymorphism.

Answer: – Overloading is compile time polymorphism where more than one methods share the same name with different parameters or signature and different return type.

Overriding is run time polymorphism having same method with same parameters or signature, but associated in a class & its subclass.

Compile time PolymorphismRun time PolymorphismIn Compile time Polymorphism, call is resolved by the compiler.In Run time Polymorphism, call is not resolved by the compiler.It is also known as Static binding, Early binding and overloading as well.It is also known as Dynamic binding, Late binding and overriding as well.Overloading is compile time polymorphism where more than one methods share the same name with different parameters or signature and different return type.Overriding is run time polymorphism having same method with same parameters or signature, but associated in a class & its subclass.It is achieved by function overloading and operator overloading.It is achieved by virtual functions and pointers.It provides fast execution because known early at compile time.It provides slow execution as compare to early binding because it is known at runtime

 

Question: – Write a code for multiple handling windows?

Answer: –

public void test() throws Exception {
// Opening site
driver.findElement(By.xpath(“//img[@alt=’SeleniumMasterLogo’]”)).click();
// Storing parent window reference into a String Variable
String Parent_Window = driver.getWindowHandle();
// Switching from parent window to child window
for (String Child_Window : driver.getWindowHandles())
{
driver.switchTo().window(Child_Window);
// Performing actions on child window
driver.findElement(By.id(“dropdown_txt”)).click();
List  dropdownitems=driver.findElements(By.xpath(“//div[@id=’DropDownitems’]//div”));
int dropdownitems_Size=dropdownitems.size();
System.out.println(“Dropdown item size is:”+dropdownitems_Size);
((WebElement) dropdownitems.get(1)).click();
driver.findElement(By.xpath(“//*[@id=’anotherItemDiv’]”)).click();
}
//Switching back to Parent Window
driver.switchTo().window(Parent_Window);
//Performing some actions on Parent Window
driver.findElement(By.className(“btn_style”)).click();
}

 

Question: -How do you handle synchronization in selenium?

Answer: – By using wait we can handle synchronization in Selenium.

 

Question: – Why do we need Software Testing Metrics?

Answer: – Metrics provide insight into the project’s status in relation to predefined goals.    It is important to measure the efficiency and effectiveness of the Test processes. Without metrics, how would you know that everything is right OR something needs your attention!

Helps in decision-making for next phase of activities, process or technology change.

Easy for management to digest one number and drill down, if required.

Different Metric(s) trends act as monitor when the process is going out-of-control.

Evidence of the claim or prediction.

Help us judge how efficient the testing efforts are.

Make proactive and informed decisions

 

Question: – 7 Soft skills every ‘QA Tester’ needs:

Answer:

Know how to ask the right questions, and when to ask them

Know how to listen

Know how to focus on what business stakeholders care about … and forget the rest

Know how to play well with others: Take a developer to lunch

Know how to deal with bullies

Know how to manage your time effectively

Know how to trust your judgment — and your intuition

 

Question: – What is the most challenging situation you have had in your Testing experience?

Answer: – As you might have guessed, it depends on each tester’s experience. The challenge can be technical, process-oriented, people’s related, domain specific OR anything within your Testing experience. For me,

Testing a technically-challenging application such as social-connected applications, application involving multiple third-party interfaces, cloud-big data-IoT-Analytics-etc. applications.

Maintaining a balance between design/execution efficiency and defect detection. Improving the Test coverage. Sticking to agile principles.

Resources on unplanned leaves, some even abscond. Estimation gone wrong, requiring weekend & extended working hours. Rating discussions with unhappy employees.

A team of fresher’s with limited domain knowledge. Planning for knowledge transfer sessions. The thumb rule – be realistic & tell your genuine challenges!

 

Question: – What is Automation and Manual Testing?

Answer: –

Automation: Software testing method which uses automation software, tools and scripts to run tests that repeat predefined actions, matches the developed program’s probable and real results.

Manual: The process of manual software testing involves manually running the individual tests or tasks associated with a product without the aid of scripts or other tools, in order to identify bugs or other issues. During this process, the testing team will use the application from end-user perspective.

 

Question: – How generate user defined exceptions, write syntax?

Answer: –

class MyException extends Exception

{

String s1;

MyException(String s2)

{      s1 = s2;   }

@Override

public String toString()

{

return (“Output String = “+s1);

}

}

public class NewClass

{

public static void main(String args[])

{

try

{

throw new MyException(“Custom message”);

}

catch(MyException exp)

{

System.out.println(exp);     ‘

}

}

}

 

Question: – Difference between throw and throws keyword?

Answer: –

throwthrowsJava throw keyword is used to explicitly throw an exception.Java throws keyword is used to declare an exception.Checked exception cannot be propagated using throw only.Checked exception can be propagated with throws.Throw is followed by an instance.Throws is followed by class.Throw is used within the method.Throws is used with the method signature.You cannot throw multiple exceptions.You can declare multiple exceptions e.g.
public void method()throws IOException,SQLException.

Handle DropDown using select Class in selenium

Handle DropDown using select Class in selenium

 

1. Overview

In this article, we’ll explore the select class from the org.openqa.selenium.support.ui.Select package to work on Drop-Down.

2. Type of DropDowns/DropBox/ListBox

There are generally two types of DropDowns

  1. Single select DropDown
  2. Multi-select DropDown

  • Single select DropDown when we can select only one option from the DropDown list like below:

Values to select will be displayed like this:

  • Multi-select DropDown when we can select more than one option from the DropDown list like below

3. Role of Select Class in Selenium:

  • The Select class is a WebDriver class which provides the implementation of the HTML

  • This class can be found under org.openqa.selenium.support.ui.Select package.

  • Select is an ordinary class as any other class , so its object is created by passing the WebElement to its constructor.

  • It will throw error as asking to add arguments to the command:

            Syntax : Select select = new Select(); 

So, specify the web element location using the select Element as done below:

Declaring the dropDown element as an instance of the Select class

Let’s find out what operations we can perform with the help of this Select class reference i.e. selectFromDropDownObj

 

Select Methods

As it can be seen from the above figure, we can select/deselect the values from the drop-down list based on our requirements.

Let’s explore some of the above methods to get better understanding of the same:

We can select our drop-down values with these below methods

  1. selectByIndex
  2. SelectByVisibleText
  3. selectByValue

Let’s examine the below code first:

  • selectByIndex (int index): This Function takes an index value from drop-down list and it starts from 0 for the first value and returns void.
  • selectByVisibleText(String text): This Function takes text in String format from the drop-down list and returns void.
  • selectByValue(String value): For this first inspect the element from DOM and select the value as shown below:

Note : The Most preferred way is to select by byVisibleText() because in ByIndex(),  index can be changed for dynamic drop down values but it can be used for static dropdown values like Month, Year and Date. 

Let’s explore getOptions Method:

Syntax:

List<WebElementallOptionsObj =selectFromDropDownObj.getOptions();

for(WebElement getAllOptions:allOptionsObj)
System.out.println(getAllOptions.getText());

This will print all the options contains in the DropDown and we get our Output same as below:

 

console Output

Another useful Method isMultiple:

This method tells us whether dropDown is single select or multi-select, it doesn’t accept anything and returns a boolean value.

 

isMultiple()

Now, if requirements changed that selected value needs to be deselected then we can perform below actions on the same.

  • deselectByIndex(int index) : void –Deselect the option at the given index.
  • deselectByValue(String Value): void –Deselect the matching option with given argument Value.
  • deselectByVisibleText(String Text) : void – Deselect the matching option with given argument Text.

Now, let’s jump into the second Type of DropDown i.e Multi-select:

Before that let’s take a glance at below code

 

select Multiple options

  1. In the above code , we first inspect the select element and then as usual instead of one select methods we can use more than one select methods. 
  2. One catchy method here is getFirstSelectedOption() it returns the WebElement and display which value from the dropdown is selected first by using getText.

That’s it we have mastered over the select class.

Below code for your reference and output of the same:

 

and output on the browser will be similar to :

package com.example.automation;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.support.ui.Select;
import java.util.List;

public class SeleniumConfig {

public static void main(String[] args) throws InterruptedException {

String path = System.getProperty(“user.dir”);
System.setProperty(“webdriver.chrome.silentOutput”, “true”);
System.setProperty(“webdriver.chrome.driver”, path + “/chromedriver”);

WebDriver driver = new ChromeDriver();
driver.get(“https://testuserautomation.github.io/DropDown/”);

//inspect over the Drop Down menu
WebElement selectCitiesObj = driver.findElement(By.xpath(“//select[@name=’Cities’]”));
Select selectFromDropDownObj = new Select(selectCitiesObj);

//select by index , index will start from 0 for first value
selectFromDropDownObj.selectByIndex(0);

//select by value, value to be found in HTML DOM
selectFromDropDownObj.selectByValue(“Texas”);

//select by Text given in the dropDownList
selectFromDropDownObj.selectByVisibleText(“CA”);

//getOptions : to get all the options from the drop-down
List allOptionsObj = selectFromDropDownObj.getOptions();

for (WebElement getAllOptions : allOptionsObj)
System.out.println(getAllOptions.getText());

//isMultiple : is it multi select drop-down if no then it returns false:
boolean isSuccess = selectFromDropDownObj.isMultiple();
System.out.println(isSuccess);

//MultiSelect DropDown
WebElement selectBillsObj = driver.findElement(By.xpath(“//select[@id=’Bill’]”));
Select selectBillFromDropDownObj = new Select(selectBillsObj);

selectBillFromDropDownObj.selectByValue(“Travel”);
System.out.println(selectBillFromDropDownObj.getFirstSelectedOption().getText());
selectBillFromDropDownObj.selectByIndex(3);
driver.close();

}
}

4.Conclusion

In this article , we have learnt about the handling of drop-down using select class in selenium.

Handling of Dynamic Web Table in Selenium

  1. Overview

In this article , we will learn to handle Dynamic Web Table in Selenium WebDriver .

2. Basic Concepts:

  • A table with rows and columns on a web page is called a web table. In HTML, a table is created using  tag. 
  • Table contains  headers represented as, rows asand Coloums as tag
  • There are two types of web Tables

  1. Static web table: Number of rows and columns will be static means constant that will not be changed. Here we just need to find the WebElement of the particular row or column and simply can perform operations on the cell.
  2. Dynamic table: Number of rows and columns will be dynamic. It will be kept on changing based on data and this the area where we will be focussing on.

3. Ways to Handle Dynamic WebTable:

  1. The standard way where we will iterate over the rows and columns and reach to a particular cell and get the cell value.
  2. By using custom XPath

Before proceeding further, let’s see how dynamic table looks like :

Table with checkbox , rows and coloumns

And below is the HTML representation of the above web table:

So, based on the data input we can increase or decrease our number of rows or columns.

Since we have seen what a web table is and how it is created, now let’s take the simple scenario :

1)click on checkbox where firstName is Will and remember it’s a dynamic table, hence “WILL” now on 3rd row can be shifted to other row based on the insertion or deletion of data.

  • Let’s implement it by First Method:

Let’s accomplish this task first by looking at the code snippet below

We’ll break this code into steps to get a deeper understanding of it:

Step1 : Capture xpath of the FirstName Row and observe the pattern

  • First Row xpath: //table/tbody/tr[2]/td[2] –>jessica
  • second Row xpath: //table/tbody/tr[3]/td[2] –>Ammy 
  • Third Row xpath: //table/tbody/tr[4]/td[2] –>Will and so on
  • Here can we say that our rowis getting changed and our columnis constant.

Step2: Catch before and after XPath from the point our row started changing as done in the code.

Step 3: Now, we have captured the before and after XPath.Find out the total row size by size() function of the java collections.

Step 4: Start iterating over the rows, start the row index with 2 as the first row would be reserved for headers.

Step 5:Get the text of all the rows and store it to the variable firstNames and print it to see if we are able to capture it

Step 6 : Final step of our task , that click the checkbox where FirstName is Will

For this step, we put one condition that if firstNames contains WILL then only checkbox has to be clicked. if it exists it will click the checkbox prior to WILL.

Since WILL is existing in the table , it will click the checkbox and we can capture it from the browser:

and our output on the console is similiar to following :

  • By Second Method : with Custom XPath

We can achieve our task with single statement :

 driver.findElement(By.xpath(“//td[contains(text(),’Will’)]//preceding-sibling::td//input[@type=’checkbox’]”)).click();

yes , that ‘it , below code for your reference

Let’s try to understand this method :

firstly visit over XPath_Axes , here you will get to know how to traverse from one node to another node.

Next, in the above we have spied over FirstName with text Will and we found out Will Sibling is td when we proceed upwards and then we get our input as a checkbox and from here we can simply capture it.

4. Which Method to choose

As can be conveyed from the above methods, the custom method is the best way to handle web dynamic table :

Reasons :

  1. In the First Method, it’s a lengthy method whereas the second method is just a single line statement
  2. In the first Method, we had to use for loop with conditions and then selecting the value, on the other hand, we need not have to use for loop
  3. As we are iterating through till all the rows it makes code slower in the first Method considering the other method can be seen fast, dynamic and efficient

Code Snippet with both methods :

package com.example.automation;
import java.util.List;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
/**

public class SeleniumConfig {
public static void main(String[] args) {
String path = System.getProperty("user.dir"); System.setProperty("webdriver.chrome.silentOutput", "true"); System.setProperty("webdriver.chrome.driver", path + "/chromedriver");
WebDriver driver = new ChromeDriver(); driver.get("https://testuserautomation.github.io/WebTable/");
// Method 1
String before_xpath = "//table/tbody/tr["; String after_xpath = "]/td[2]";
List rows = driver.findElements(By.xpath("//table/tbody/tr"));
int rowSize = rows.size();
System.out.println(rowSize);
for (int i = 2; i <= rowSize; i++) {
String firstNames = driver.findElement(By.xpath(before_xpath + i + after_xpath)).getText();
System.out.println(firstNames);
// Now click the checkBox where first Name would be Will
if (firstNames.contains("Will")) {
// click the checkBox
driver.findElement(By.xpath("//tbody/tr[" + i + "]/td[1]/input")).click(); System.out.println("candidate has been selected");
break;
}
}
// Method 2 : By custom xpath:
driver.findElement(By.xpath("//td[contains(text(),'Will')]//preceding-sibling::td//input[@type='checkbox']")) .click();
driver.close();
}
}

5. Conclusion

In this article , we learnt about how to handle dynamic Web Tables.
