According to worldwide Google Trends of the IT sector, the demand for well-trained API (Backend) testing professionals has increased substantially.
With the growing need of API testing, the tools and technologies are progressing hand-in-hand which focuses on improving performance, ease-of-use, reliability and accessibility.
Why Karate DSL is the best tool for API Automation ?
Karate DSL is becoming a fore-runner of the tools and technologies available, fulfilling all these parameters in a short period of time.
With 4.4K GitHub stars and 1.1K GitHub forks, Karate DSL is progressively becoming popular amongst the QA community.
It is an Open Source Web-Services Test Automation Solution that integrates in a unified framework API test-automation, performance-testing and even UI automation.
It is developed on top of Cucumber-JVM, which enables us to build API-based BDD (Behaviour Driven Development) test scenarios for testing which means Gherkin becomes the primary programming language.
However, unlike the BDD framework, Karate DSL has omitted step-definition file writing efforts for the corresponding feature file i.e. we can execute the feature file comprising of all the test cases without defining step-definition file with the help of TestRunner class.
In addition to these benefits, there are numerous points of interest recorded below:
- Karate DSL uses english-like language – Gherkin.
- Powerful JSON & XML assertions along with “deep-equals” payload assertions.
- You do not need to write additional “glue” code or Java “step definitions” Java.
- Parallel execution feature offered by Karate in turn reduces the test execution time. Hence, making it a very fast API testing tool
- For large responses, data validation becomes easier by “match” keyword.
- Data-driven tests that can also use sources from JSON or CSV
- Even for non-programmers, tests are simple to write, i.e. it is based on the common Cucumber / Gherkin standard with syntax colouring options.
Looking at the wide range of Karate DSL features, aren’t you curious about learning and using this awesome tool?
