## 🚨 Important Reminders

### Testing is Not Optional
- **100% coverage** is achievable in 15-20 hours
- **Prevents bugs** from reaching production
- **Enables safe refactoring** and improvements
- **Builds confidence** in code quality

### Test Quality Matters More Than Quantity
- **Flaky tests** are worse than no tests
- **Good tests** are self-documenting
- **Maintainable tests** are critical
- **Comprehensive coverage** requires thought

### Start Small, Scale Up
- **Phase 1**: Establish baseline
- **Phase 2**: Cover critical paths
- **Phase 3**: Cover everything else
- **Phase 5**: Automate enforcement
