Karate DSL

Karate DSL is a unique open-source tool that combines API test automation, performance testing, mocks, and even UI automation into a single, cohesive framework. Its most notable feature is that it allows you to write tests in a behavior-driven development (BDD) style using a plain-text syntax that is also a programming language. This means you can define requests, assertions, and complex logic without writing Java code, though you can seamlessly call Java if needed. It's built on top of Cucumber-JVM but eliminates the need for separate step definition files.

Karate is ideal for developers and testers who appreciate a code-based, version-control-friendly approach but want to minimize boilerplate code. It's particularly powerful for teams practicing BDD and looking for a single framework to handle API contract, functional, and performance testing.
