Karate is 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.




Cucumber is described as 'Tool that executes plain-text functional descriptions as automated tests. Collaboration tool for executable specifications which is based on "gherkin"-parser Gherkin the language that Cucumber understand' and is an app in the development category. There are six alternatives to Cucumber for a variety of platforms, including Windows, Linux, Mac, Web-based and BSD apps. The best Cucumber alternative is Karate, which is both free and Open Source. Other great apps like Cucumber are Robot framework, Testomat.io, JBehave and SpecFlow.

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.

This system organizes automated and manual tests for modern teams, enhancing transparency. Provides test analysis, BDD support, real-time reporting. Integrates with JavaScript frameworks, Jira, and Confluence for better project alignment. Facilitates branching and versioning like git.




JBehave is a framework for Behaviour-Driven Development (BDD). BDD is an evolution of test-driven development (TDD) and acceptance-test driven design, and is intended to make these practices more accessible and intuitive to newcomers and experts alike.
SpecFlow aims at bridging the communication gap between domain experts and developers by binding business readable behavior specifications and examples to the underlying implementation.
