description RestAssured Overview

For Java teams, REST Assured brings API checks into the same codebase as application tests. This open-source library provides a domain-specific language, meaning a set of expressions tailored to testing HTTP services. Its fluent syntax supports a given-when-then structure: define the request conditions, perform an operation, and check the response. Headers, parameters, and request bodies can be configured without writing all the underlying HTTP client code.

Response assertions can cover status codes and returned content, making the library useful for repeatable regression tests. It works with JUnit and TestNG and fits projects built with Maven or Gradle. Unlike a graphical request client, REST Assured expects tests to be written and maintained as code. That makes it suitable for developers who want version-controlled API checks that run with their normal build and continuous integration process.

help RestAssured FAQ

What is the difference between RestAssured and other testing tools?

RestAssured uses a Given-When-Then style that makes tests more readable, integrates seamlessly with Java frameworks, and offers extensive features for API testing.

Is RestAssured free to use?

Yes, it is open-source and available under the Apache 2.0 license, but some commercial plugins may require a subscription.

Can RestAssured be used with non-Java projects?

RestAssured is primarily designed for Java projects, so integration with non-Java environments might require additional tools or workarounds.
