Authors REST Assured (Java) API tests using the given().when().then() BDD-style DSL - status code + JSON/XML path assertions + authentication (Basic, OAuth2, API key). Configures Maven / Gradle dependencies, runs via JUnit 5, and emits Surefire / JaCoCo reports for CI gating. Use when the project is on the JVM and wants type-safe API tests in the app's own language; for a Gherkin feature-file flow on the same JVM use karate-testing, for YAML tests on the pytest stack use tavern-testing.
