Software:Karate ( test-automation)
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 also has support for service-virtualization where it can bring up "mock" (or stub) servers which can substitute for web-services that need to participate in an integration-test. Karate's capabilities include being able to run tests in parallel, HTML reports and compatibility with Continuous Integration tools.
Karate is implemented in Java but test-scripts are written in Gherkin since Karate was originally an extension of the Cucumber framework.
History
Karate was created by Peter Thomas.[1]
Basic usage
This example shows what a simple Karate test script looks like and how it is based on the Gherkin syntax.
Feature: karate 'hello world' example
Scenario: create and retrieve a cat
Given url 'http://myhost.com/v1/cats'
And request { name: 'Billie' }
When method post
Then status 201
And match response == { id: '#notnull', name: 'Billie' }
Given path response.id
When method get
Then status 200
This actually makes two calls, first an HTTP POST to 'http://myhost.com/v1/cats' and then a GET to the same URL but with the value of response.id appended as a REST-ful path parameter. The match keyword is used for asserting that a given payload is as expected. The use of the #notnull "fuzzy match" token takes care of "ignoring" the actual value since it is dynamic, as it is a server-side auto-generated identifier.
Features
- Although based on Cucumber, Karate does not require the user to write extra "step-definitions", which saves a lot of effort. Tests are fully described in Gherkin.[2]
- Built-in support for switching the environment[3]
- Comprehensive support for HTTP, including SOAP/XML, HTTPS, HTTP proxies, URL-encoded form data, multi-part file uploads[3]
- HTTP API mocks
- Integration with popular Java unit-testing frameworks such as JUnit[4]
- Compatibility with continuous integration tools[4]
- Web-browser automation of Chrome via the Chrome DevTools Protocol
- Cross-browser automation via the W3C WebDriver specification
Reception
Karate was featured as one of the top 5 open-source API testing tools within six months of its release.[5] It was also mentioned as one of the 10 API testing tools to try in 2017.[3]
Karate was first listed in the ThoughtWorks Technology Radar in 2019[6] with a rating of "Assess". One year later it moved into the "Trial" category in May 2020.[7]
