golang-gin-testing — Testing REST APIs

Write confident tests for Gin APIs: unit tests with mocked repositories, integration tests with real PostgreSQL via testcontainers, and e2e tests for critical flows. This skill covers the 80% of testing patterns you need daily.

When to Use

• Writing tests for Gin handlers (UserHandler, AuthHandler)
• Testing services with a mocked UserRepository
• Setting up integration tests with a real database (testcontainers)
• Testing JWT auth middleware in isolation
• Adding table-driven tests for request validation and error paths
• Setting up TestMain for shared test infrastructure
