karate

Karate is an open-source testing tool that brings several kinds of automated testing together in one place. Instead of using separate tools for testing APIs, simulating fake server responses, checking performance under load, and automating a web browser, Karate offers a single framework that covers all of those. The idea is that a team can write tests for all these concerns without switching tools or learning multiple systems.

The project is written in Java and sits in the same ecosystem as tools like Cucumber, which lets teams write tests in plain readable sentences rather than dense code. The topics associated with Karate include API testing, contract testing, and behavior-driven development, which is a style of testing that frames checks as descriptions of how software should behave. These kinds of tests are typically written by developers or quality-assurance engineers who want to verify that one system talks to another correctly.

The current README is sparse and points readers to external documentation at docs.karatelabs.io for details. Version 2 of the library is in active development, with notes available in a separate file in the repository. The project is hosted under the karatelabs organization on GitHub and has a commercial company behind it offering support resources.

For a non-technical reader, the short version is: Karate is a toolkit for checking that software systems communicate correctly and behave as expected, aimed at development teams who want one consistent tool rather than several. The full documentation lives outside this repository.
