REST Assured is a Java-based library that allows you to test RESTful web services. REST Assured enables developers to create expressive and succinct tests that are simple to maintain and understand. It facilitates RESTful API testing and validation by providing a domain-specific language (DSL) for making HTTP requests and verifying answers.
- REST Assured supports many HTTP methods, including GET, POST, PUT, DELETE, and others.
- It supports authentication techniques, request and response headers, cookies, and other RESTful API capabilities.
- The library can create automated tests using testing frameworks such as JUnit or TestNG.
Why Rest Assured?
- REST Assured provides a straightforward and intuitive DSL for making HTTP queries and validating replies, making testing RESTful APIs easier.
- REST Assured supports HTTP methods like GET, POST, PUT, DELETE, and others, allowing developers to test all parts of a RESTful API.
REST Assured supports different authentication mechanisms, including Basic authentication, OAuth, and JWT, allowing developers to test APIs that require authentication.
- REST Assured includes built-in validation mechanisms for evaluating status codes, headers, and response bodies. This ensures that the API behaves correctly.
- REST Assured is easily linked with common testing frameworks like JUnit or TestNG, making creating and running automated tests simple.
