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.

Steps to Configure Maven Profile with Maven Project

Let us see how to configure Maven Profile for a Maven Project.

What is a Maven Profile..??                                                               

It is a feature that can be defined in a pom.xml file which allows developers and testers to configure and customize builds based on requirement. 

What is the advantage of implementing Maven Profile in our Automation Projects..??                                                                 

As shown below, In real time we generally maintain different testng.xml files in frameworks that are designed either for Web Applications, Backend APIs or Mobile Applications like Smoke Suite, Regression Suite, Sanity Suite etc. for executing test cases based on requirement.             

Based on business requirement, we will be required to execute testng.xml files from Eclipse IDE, Command Prompt or from Jenkins etc.

In general, if we do not use Maven Profiling. Each time when we need to execute testng.xml file. We need to go to pom.xml file and change the name of testng.xml inside Maven Surefire Plugin which needs to be executed and that is a very tedious task to do every time.  Now the question is, how can we avoid changing testng.xml file name in pom.xml every time. when we need to execute test suite.

Now let us see configuring Maven Profile with Maven Project.

1. Project should be a Maven Project. 

2. Maven Jar files should be downloaded and path must be set for the same in Environment Variables and ensure that you are able to execute Maven Project from Command Line prompt before implementing Maven Profile. 

Refer below blog with respect to above points to Install Maven Jars and to execute Maven Project from Command Prompt:  http://naveenautomationlabs.com/executing-maven-project-in-windows-from-command-prompt/

Below is Maven Surefire Plugin where we mention which testng.xml file needs to be executed from project.

Code for Maven Surefire Plugin:                                                     

<build>
 <pluginManagement>
 <plugins>
 <plugin>
 <groupId>org.apache.maven.plugins</groupId>
 <artifactId>maven-surefire-plugin</artifactId>
 <version>2.18.1</version>
 <configuration>
 <suiteXmlFiles>
 <suiteXmlFile>src/main/resources/testng_smoke.xml</suiteXmlFile>
 </suiteXmlFiles>
 </configuration>
 </plugin>
 </plugins>
 </pluginManagement>
 </build>

Now, let us see how can we build Maven Profile using Maven Surefire Plugin.

We can build Maven Profile for each testng.xml file in pom.xml as shown below, for each Maven Profile we can give Id/Name as highlighted in below screenshot.

All we need to add is followed tags with Maven Surefire Plugin <profiles> </profiles>, <profile> </profile> and <id> </id>.

All we need to do is that providing Id/Name for each Profile. For example, if we have multiple testng.xml files like Smoke, Sanity and Regression then we can build 3 Maven Profiles.       

One-One Profile for each suite, so that we can avoid changing testng.xml file name inside Maven Surefire Plugin whenever we need to execute test suite.

In my case, I have 2 testng.xml files. One is for Smoke and other one is for Regression.

You can refer below screenshots for giving Maven Profile Names for Test Suites.

Note: Profile Name should always be written inside <id> tag.

Refer below pom.xml to build Maven Profile for each testng.xml file.    https://github.com/PavanReddy77/MavenSurefirePlugin/blob/master/pom.xml

Once Maven Profiles are built for all testng.xml files then we are good to execute from Command Prompt or from Jenkins.

Maven Commands to be followed when executing testng.xml files. 

mvn test –P followed by Maven Profile Id like below:

mvn test –PSmoke     

mvn test –PRegression

Well, we are now good to execute our testng.xml file based on our requirement.

Refer below repository for implementing Maven Surefire Plugin and Maven Profile.

Conclusion: In this blog, we have seen implementing Maven Surefire Plugin and Maven Profile in a Maven Project.

Steps to Configure Maven Project with Jenkins

Jenkins is an Open Source Continuous integration tool that is written in Java which is often used in Devops.

It is mainly used by Developers and Testers, whenever Developers/Testers does any changes in Source Code then Jenkins will automatically pull the code and continuously build and test code that has been added.           

Step 1: Installing Jenkins War File.

Follow below steps to install Jenkins War File. 

Go to any browser and search by Jenkins Download as shown below and click on  below highlighted link.

After clicking on above highlighted link, you will be navigated to below page.      

Click on “Permalink to the latest” – Latest and Stable version of Jenkins War File will be installed into your local system.

Now you are good to execute your Jenkins War File from Command Prompt.

Step 2: Executing Jenkins War File from Command Prompt.

Create a separate folder in your local system and place Jenkins War file once it is downloaded. Note: We must run Jenkins.war file through Command Line Prompt.

Step 3: Use below command to Run Jenkins.war file

Note:  By default, Jenkins will always run in localhost:8080. Make sure nothing else is running on port 8080. If localhost:8080 is already occupied then you won’t be able to execute Jenkins.war file.                    In such case you can execute your Jenkins.war file in other port using below command.

Once Jenkins is successfully launched, user should be able to see below message in
Command Prompt.

“Jenkins is Fully Up and Running”.

Step 4: Now, go to browser and open localhost:8084 where you have run your Jenkins.               
In my case, I have run Jenkins in port 8084.                                                                            

When launching it for first time, you have to set username and password and install default plug-ins that suggests etc and then you will be landed on to Jenkins Dashboard Page. 

Step 5: Configure your system for Java and Maven in Jenkins as shown below                

Go to Manage Jenkins >> Global Tool Configuration.

Step 6: Install Required Plug-ins >> Go to Manage Jenkins >> Manage Plug-ins and install from Available Section.

Step 7: Create Job >> New Item >> Enter Item Name >> Select Maven Project and Click on OK. After installing all Maven Plug-ins user should be able to see Maven Project Option.

Step 8:                                                                                                                                           A. Go to General >> Enter Description of your Project.

B. Go to Maven Info Plug-in Configuration >> Select None.

C. Go to Source Code Management. [You have to select any one option from it].       

Select None, if you are not using any Source Code Management tool for maintaining Code.

Select Git and provide Repository URL and Branch Name, if you are maintaining code in Git.

D. Go to Build Triggers.                                                                                                      

You can select as shown below, if you are not scheduling jobs using CRON Command and such. [In this case you have to build a job manually].

If you have to schedule jobs automatically, select Build Periodically and use CRON Command. 

If we have to build a job automatically when in any commit happens to Git then we
can select Poll SCM and use CRON Command.                                                                 

[As soon as code commit happens to Git, it will trigger a build].

E. From Build Environment, Select None

F. From Pre Steps, Select None.

G. From Build, Enter Path for your Root POM.xml and command to be executed as shown below.                                                                                                                  
Note: When in giving Maven Command to Run Test Cases in Jenkins, ignore mvn and just give commands as below.                                                                                
clean install Or test Or test -PSmoke etc.

H. From Post Steps, you can select any option as per your requirement.

I. If you want to be notified, when in any job is getting failed then you can select Build Settings and configure it.

Note: To do this we need to do other extra configuration [You can ignore for it now].

J. Post Build Actions can be used to Generate Results. [To achieve it, we need to install required plug-ins like TestNG Plug-in, HTML Report Plug-in for Generating Extent Report]

Below Configurations needs to be done for generating Extent Reports in Project Folder.

Step 9: Apply and Save, now click on Build now to trigger your Job.

Conclusion: In this blog, we have seen how to create a Job for Maven Project, Configuring Job and Executing a Job in Jenkins.
