Karate is described as 'The only open-source tool to combine API test-automation, mocks, performance-testing and even UI automation into a single, unified framework. The BDD syntax popularized by Cucumber is language-neutral, and easy for even non-programmers' and is a automated testing tool in the development category. There are six alternatives to Karate for a variety of platforms, including Windows, Linux, Mac, BSD and Ruby apps. The best Karate alternative is Geb, which is both free and Open Source. Other great apps like Karate are Cucumber, Robot framework, JBehave and BDDX.

Cucumber is a tool that executes plain-text functional descriptions as automated tests. Collaboration tool for executable specifications which is based on "gherkin"-parser Gherkin is the language that Cucumber understand.

Robot Framework is a generic test automation framework for acceptance testing and acceptance test-driven development (ATDD). It has easy-to-use tabular test data syntax and it utilizes the keyword-driven testing approach.


SpecFlow aims at bridging the communication gap between domain experts and developers by binding business readable behavior specifications and examples to the underlying implementation.
