Production Validation vs Unit Testing (+1)
Production Validation vs Unit Testing
| Aspect | Unit Tests (TDD) | Production Validation |
|---|---|---|
| Dependencies | Mocked | Real |
| Database | In-memory/fake | Actual PostgreSQL/etc |
| APIs | Stubbed responses | Live service calls |
| Purpose | Design/logic | Deployment readiness |
| Speed | Fast (ms) | Slower (seconds) |
Validation Categories
- Implementation Completeness: No mock/stub/fake code in production
- Database Integration: CRUD operations on real database
- External APIs: Actual service integrations work
- Infrastructure: Cache, email, queues function correctly
- Performance: Meets latency and throughput requirements
- Security: Authentication, authorization, input validation
