Go Integration Testing

Overview

Integration tests with real dependencies using testcontainers-go. No mocks for infrastructure — test against actual Postgres and Redis.

Core principle: If it talks to a database, test it with a real database.

When to Use

• Testing repository implementations against real Postgres
• Testing Redis cache/session logic
• Full HTTP lifecycle tests (handler → use case → repo → DB)
• Verifying migration correctness
