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.

• MANDATORY: Run ./mvnw compile or mvn compile before applying any change
• PREREQUISITE: Project must compile successfully and pass basic validation checks before any test refactoring
• CRITICAL SAFETY: If compilation fails, IMMEDIATELY STOP and DO NOT CONTINUE with any recommendations
• BLOCKING CONDITION: Compilation errors must be resolved by the user before proceeding with integration test changes
• NO EXCEPTIONS: Under no circumstances should testing recommendations be applied to a project that fails to compile
• VERIFY: Run ./mvnw clean verify or mvn clean verify after applying improvements
• BEFORE APPLYING: Read the reference for detailed rules and examples

When to use this skill

• Add Micronaut integration tests with Testcontainers
• Wire dynamic datasource or broker URLs for @MicronautTest

Workflow

1. Read reference and assess project context

Read references/522-frameworks-micronaut-testing-integration-tests.md and inspect the current project setup before proposing changes.

1. Gather scope and decide target improvements

Identify requested outcomes, constraints, and the minimum safe set of changes to apply.

1. Apply framework-aligned changes

Implement or refactor configuration/code following the reference patterns and project conventions.

1. Run verification and report results

Execute appropriate build/tests and summarize what changed, what was verified, and any follow-up actions.
