API Automation Made Simple using Karate framework


Karate Framework for beginners


API Automation with Karate Framework.


API Automation using Karate Framework


Karate Framework


Karate is an open-source general-purpose test-automation framework that can script calls to HTTP end-points and assert that the JSON or XML responses are as expected. Karate is implemented in Java but test-scripts are written in Gherkin since Karate was originally an extension of the Cucumber framework.


Karate is built on top of Cucumber, another BDD testing framework, and shares some of the same concepts. One of these is the use of a Gherkin file, which describes the tested feature. However, unlike Cucumber, tests aren't written in Java and are fully described in the Gherkin file.


From this course, you will learn the following concepts.


Karate configuration


Overview on API with examples


Overview on JSON with examples


Live example of API calls


Karate Framework


GET/POST Request


Data-Driven with Scenario Outline


Creating Parallel runner


Assertions


Using match


JSON Array matching


Schema validation


Fussy matcher: #string, #number


calling another feature


Tags and Run with tags


karate runner configuration and karate options
