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
Workflow
- Read reference and assess project context
Read references/422-frameworks-quarkus-testing-integration-tests.md and inspect the current project setup before proposing changes.
- Gather scope and decide target improvements
Identify requested outcomes, constraints, and the minimum safe set of changes to apply.
- Apply framework-aligned changes
Implement or refactor configuration/code following the reference patterns and project conventions.
- Run verification and report results
Execute appropriate build/tests and summarize what changed, what was verified, and any follow-up actions.
