Agent skill

422-frameworks-quarkus-testing-integration-tests

Use when you need to write or improve integration tests for Quarkus — including @QuarkusTest, Dev Services for automatic container provisioning, Testcontainers via QuarkusTestResourceLifecycleManager, WireMock for external HTTP stubs, @QuarkusIntegrationTest for black-box testing against packaged artifacts, REST Assured, data isolation strategies (@TestTransaction vs @BeforeEach cleanup), and Maven Surefire/Failsafe three-tier split (*Test, *IT, *AT).

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.

Constraints

Compile before changes; verify after; Docker may be required for containers.

  • MANDATORY: Run ./mvnw compile or mvn compile before applying any change
  • PREREQUISITE: Project must compile before applying integration test improvements
  • SAFETY: If compilation fails, stop immediately
  • BLOCKING CONDITION: Compilation errors must be resolved by the user before proceeding
  • VERIFY: Run ./mvnw clean verify or mvn clean verify after applying improvements; Docker is required for Testcontainers and Dev Services
  • BEFORE APPLYING: Read the reference for detailed rules and examples

When to use this skill

  • Add or improve integration tests in a Quarkus project
  • Configure Testcontainers or Dev Services for Quarkus tests
  • Add WireMock stubs for external HTTP dependencies in Quarkus integration tests
  • Set up @QuarkusIntegrationTest for packaged artifact or native binary testing
  • Fix test data isolation or configure Maven Surefire/Failsafe split
