⏱️ Time Estimates
By File Type
- Value Objects (2 files): 30-45 minutes
- DTOs (10 files): 2-3 hours (using templates)
- Controllers (2 files): 1.5-2 hours
- Repositories (3 files): 2.5-3.5 hours
Total: 9-14 hours
Recommended Order
- Value Objects (fastest, builds confidence)
- DTOs (quick, many file repetition)
- Controllers (medium complexity)
- Repositories (most complex, worth doing last)

💡 Pro Tips
- Start Small: Begin with Value Objects (simplest)
- Copy-Paste: Use templates, don't write from scratch
- Test Early: Run tests as you write them
- Be Thorough: Include both happy and error paths
- Use Existing: Reference existing tests in the codebase
- Verify Formulas: Test arithmetic calculations carefully
- Mock Everything: Don't hit real database in tests
- Test Guards: Don't forget authentication/authorization
