Karate DSL vs RAML: What are the differences?

  1. API Description: Karate DSL focuses on BDD-style API testing and operates by creating API test scripts in a simple, readable format. On the other hand, RAML (RESTful API Modeling Language) is used for designing APIs by defining the resources, methods, parameters, etc., in a more structured and formalized manner.

  2. Testing Capabilities: Karate DSL includes built-in capabilities for API testing, such as request/response validation, data-driven testing, and scenario outline support. In contrast, RAML primarily focuses on API design and documentation, lacking built-in testing features like those provided by Karate DSL.

  3. Community Support: Karate DSL has a smaller but dedicated community that actively contributes to the development and improvement of the tool. On the other hand, RAML has a larger community with extensive resources and support for API designers and developers.

  4. IDE Integration: Karate DSL offers seamless integration with popular IDEs like IntelliJ IDEA, Visual Studio Code, and Eclipse, providing a streamlined development experience. In comparison, RAML lacks direct IDE integration, requiring users to rely on plugins or external tools for editing and validation.

  5. Scripting Language: Karate DSL uses a custom syntax and DSL for scripting API test scenarios, allowing users to write tests without prior knowledge of programming languages. In contrast, RAML uses YAML for defining API specifications, requiring users to have familiarity with the YAML language to create API designs.

  6. Execution Environment: Karate DSL can be run on the JVM (Java Virtual Machine) platform, offering cross-compatibility and easy integration with Java-based projects. In contrast, RAML tools may vary in terms of execution environments depending on the specific implementation and deployment requirements.

In Summary, Karate DSL focuses on BDD-style API testing with built-in capabilities, while RAML is primarily used for designing structured APIs with extensive community support.

Karate DSL

RESTful API Modeling Language (RAML) makes it easy to manage the whole API lifecycle from design to sharing. It's concise - you only write what you need to define - and reusable. It is machine readable API design that is actually human friendly.

Combines API test-automation, mocks and performance-testing into a single, unified framework. The BDD syntax popularized by Cucumber is language-neutral, and easy for even non-programmers. Besides powerful JSON & XML assertions, you can run tests in parallel for speed - which is critical for HTTP API testing.

Create and pull in namespaced, reusable libraries, containing data types; Annotations let you add vendor specific functionality without compromising your spec; Traits and resource Types let you take advantage of code reuse and design patterns; Easily define resources and methods then add as much detail as you want
Native support for both JSON and XML; Powerful payload assertions with "deep-equals"; Data-driven testing; Easy even for non-programmers; Embedded JavaScript engine; Test-doubles or HTTP mocking built-in; Re-use test scripts as performance-tests; Environment switching; Comprehensive reports, supported by all CI tools
