REST Assured

REST Assured is a Java library for simplifying the testing and validation of RESTful APIs. It provides a fluent domain-specific language (DSL) built on the given-when-then BDD pattern, making it easy to write readable and maintainable API tests. REST Assured supports HTTP methods GET, POST, PUT, DELETE, OPTIONS, PATCH, and HEAD, along with JSON and XML response validation, JSONPath and XmlPath parsing, multiple authentication schemes, Spring MockMvc integration, and full request/response logging. Version 6.0.0 requires Java 17+ and integrates with Groovy 5, Spring 7, and Jackson 3. The library is distributed via Maven Central under the io.rest-assured group ID and is used by tens of thousands of development teams for API automation testing.

REST Assured publishes 1 API on the APIs.io network. Tagged areas include Functional Testing, Testing, Java, API Testing, and Automation.

The REST Assured catalog on APIs.io includes 1 JSON-LD context and 1 Spectral governance ruleset.

REST Assured’s developer surface includes documentation, support, and 6 more developer resources.
