## Branching & Path Coverage

### Current Branch Coverage
- **Overall Branch Coverage**: Lower than statement coverage (estimated ~50%)
- **Key areas with branch issues**:

  - Complex services (decision trees)
  - Error handling (exception paths)

### Phase 2 Will Address
- Add tests for all if/else branches
- Test error conditions and exceptions
- Test loop iterations and break conditions
- Test all conditional combinations

## Technical Debt & Notes

### Items to Address
1. **Schemas module**: Appears unused - consider deprecation
2. **Testing factories**: 20 uncovered lines - integrate into tests
3. **Logging config**: Not tested - need basic test
4. **CLI commands**: Heavy coverage gaps - systematic test creation needed

### Opportunities
1. **Test generation**: Many CLI commands follow patterns - could automate
2. **Test data**: Factories exist but not fully utilized
3. **Async patterns**: Good async test support in place
4. **Performance**: Tests run in 51s - room for optimization

---

## Report Summary

**Status**: ✅ Phase 1 Complete

**Current State**:
- 975 tests passing
- 66.75% statement coverage
- Good foundation to build on

**Next Phase**: 
- Create tests for 0% coverage areas
- Improve low coverage modules
- Target 80-85% coverage in phase 2

**Timeline**:
- Phase 2: 8-10 hours → 80-85% coverage
- Phase 3: 5-7 hours → 90-95% coverage  
- Phase 4-5: 3-5 hours → 100% coverage
- **Total**: 16-22 hours from baseline to 100%
