REST Assured
REST Assured is a Java library for testing RESTful web services through programmatic HTTP requests and response assertions.
BDD in Action, Second Edition
REST Assured is a Java library for testing and validating REST-based HTTP APIs through programmatic requests and response assertions.
- How it is used
- Automates business requirements and user journeys through REST API calls instead of relying exclusively on slower, fragile UI tests.
- How deep it goes
- Explains request construction, URI configuration, JSONPath extraction, response mapping, and focused assertions, but not library internals.
- Examples
- Demonstrates frequent flyer registration, account retrieval, JSON response samples, Java records, and tier-and-points assertions.
- What you can do after
- Apply it via Java to build automated acceptance tests that call REST endpoints, inspect JSON responses, and validate business outcomes.

Quarkus in Action
REST Assured is a Java library for testing RESTful web services through programmatic HTTP requests and response assertions.
- How it is used
- Tests Quarkus REST endpoints through HTTP requests and response assertions.
- How deep it goes
- Demonstrates a GET assertion and a reservation resource test, but does not detail REST Assured internals.
- Examples
- Uses a greeting GET request and a reservation submission that verifies an assigned ID.
- What you can do after
- Apply it via REST Assured to send endpoint requests and assert expected responses in Quarkus tests.
