Go Integration Tests

Generate comprehensive Go integration tests using testify suite patterns with real database and infrastructure dependencies.

When to Use

• Test use cases against real databases via containers
• Verify end-to-end flows with real infrastructure
• Assert DB state, side effects, and error conditions

Planning Phase

Before writing tests, identify:

1. Test Location: Tests go in test/integration/ mirroring the source path from internal/
   • Example: internal/modules/identity/usecase/user/user_register_usecase.go → test/integration/modules/identity/usecase/user/user_register_usecase_test.go
2. Dependencies: Identify real dependencies (database, redis) vs mocked ones (email, external APIs, metrics)
3. Test Cases: Define scenarios covering happy paths, edge cases, error conditions, and DB state verification
4. Naming: Use descriptive names: TestExecute_ValidInput_ReturnsUser, TestExecute_DuplicateEmail_ReturnsError
