description	Use when you need to write or improve integration tests for Micronaut — @MicronautTest, HttpClient, TestPropertyProvider with Testcontainers, transactional test mode where appropriate, and Maven Surefire/Failsafe splits for *Test, *Tests, *IT, and *AT. This should trigger for requests such as Add Micronaut integration tests with Testcontainers; Wire dynamic datasource or broker URLs for @MicronautTest; Write @MicronautTest integration tests with Testcontainers; Configure replacement beans for Micronaut integration tests; Review Micronaut integration test lifecycle and resources.

Micronaut Integration Testing

Prove real wiring in Micronaut with containers and HTTP.

What is covered in this Skill?

• Scope: contracts and boundaries, not duplicated unit-test logic
• TestPropertyProvider + static @Container for JDBC/Kafka properties
• HttpClient full-stack HTTP assertions
• @MicronautTest(transactional = true) for rollback where supported
• Shared containers per class; pinned image tags
• Maven Surefire/Failsafe: *Test / *Tests vs *IT / *AT; explicit plugin includes and excludes

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

Constraints

Before applying any integration test changes, ensure the project compiles. If compilation fails, stop immediately. After applying improvements, run full verification.
