Quarkus Integration Testing

Apply integration testing patterns for Quarkus with real wiring and reproducible infrastructure.

What is covered in this Skill?

• @QuarkusTest for in-JVM integration with real CDI wiring
• Dev Services for automatic container provisioning (%test.quarkus.datasource.devservices)
• Testcontainers via QuarkusTestResourceLifecycleManager (start/stop lifecycle, dynamic config injection)
• WireMock for stubbing external HTTP services via QuarkusTestResourceLifecycleManager
• @QuarkusIntegrationTest for black-box testing against the packaged JAR or native binary
• HTTP testing with REST Assured against the Quarkus test port
• Data isolation: @TestTransaction for automatic rollback; @BeforeEach cleanup for HTTP tests
• Maven three-tier split: *Test → Surefire (fast), *IT + *AT → Failsafe (verify)
• Native-image test considerations with @DisabledOnNativeImage

Scope: Apply recommendations based on the reference rules and good/bad code examples.
