Karate review

One readable syntax for API, contract, and load tests in code.

Verdict

Karate is the best code-based framework, letting engineers express API, contract, and performance tests in one readable Gherkin-style file that lives in the repo and runs through Maven or Gradle.

What customers praise

The same feature file can assert an API response and then drive a Gatling-based load test, keeping functional and performance coverage in sync.

What customers criticise

It is a developer framework, not a point-and-click app, so non-coders cannot use it and setup assumes a JVM build toolchain.

Best for

Automation engineers who want a code-based framework where API, performance, and UI tests share one readable Gherkin-style syntax.
