### Test Count: 94 Tests

- Task Model: 36 tests
- Epic Model: 13 tests
- Workflow State: 18 tests
- Storage Layer: 27 tests
- Pass Rate: 100%

## Analysis

### Strengths ✅

1. **Workflow State:** 100% coverage - Perfect implementation
2. **Task Model:** 99.3% coverage - Comprehensive testing
3. **Epic Model:** 97% coverage - Excellent coverage
4. **Storage Layer:** 79.9% coverage - Good error handling tests

### Gaps Identified 🟡

1. **Commands:** 0% coverage (728 uncovered lines)
   - Need integration tests
   - CLI interface testing required
   - Mock LLM interactions needed

2. **LLM Module:** 0% coverage (51 uncovered lines)
   - Need mock Anthropic API
   - Test prompt generation
   - Test response parsing

3. **Epic Groups:** 30.8% coverage (18 uncovered lines)
   - Need group-specific tests
   - Group lifecycle tests
   - Group validation tests

## Next Steps to Improve Coverage

### High Priority (Target: 60% total coverage)

1. **Add Integration Tests for Commands** (~400 lines)
   - Create `scud-cli/tests/integration_test.rs`
   - Mock file system operations
   - Test CLI argument parsing
   - Test command execution flow
   - Estimated impact: +35% coverage

2. **Mock LLM Client Tests** (~50 lines)
   - Create mock Anthropic responses
   - Test prompt generation
   - Test response parsing
   - Estimated impact: +4% coverage

### Medium Priority (Target: 75% coverage)

3. **Epic Groups Tests** (~20 lines)
   - Group creation/deletion
   - Epic assignment to groups
   - Group validation
   - Estimated impact: +2% coverage

4. **Command Error Handling** (~100 lines)
   - Invalid input scenarios
   - Missing dependencies
   - File permission errors
   - Estimated impact: +9% coverage

### Low Priority (Target: 85%+)

5. **Property-Based Testing**
   - Use `proptest` crate
   - Generate random valid tasks/epics
   - Fuzz test validation logic

6. **End-to-End Tests**
   - Full workflow cycles
   - Real file system operations
   - Multi-user scenarios

## Coverage Goals

| Milestone | Target | Current | Gap | ETA |
|-----------|--------|---------|-----|-----|
| v0.0.3-beta | 60% | 30.9% | +29% | 1 week |
| v0.0.4-beta | 75% | 30.9% | +44% | 2 weeks |
| v1.0.0 | 85% | 30.9% | +54% | 3-4 weeks |

## How to Run Coverage

```bash
# Install tarpaulin
cargo install cargo-tarpaulin

# Generate coverage report
cargo tarpaulin --out Html --output-dir ../coverage

# View HTML report
open ../coverage/tarpaulin-report.html
```

## CI/CD Integration

Coverage reporting is configured in `.github/workflows/coverage.yml`:
- Runs on every push/PR
- Uploads to codecov.io
- Fails if coverage drops below threshold (currently disabled)

## Notes

- **30.9% overall coverage** is accurate for current state
- Core business logic (models + storage) has **excellent coverage (85%)**
- Commands are 0% covered because they need **integration tests**
- Coverage will significantly improve with command integration tests
- Current test suite is robust for the implemented test types
