## Test Coverage by Feature

### Commands Covered
- ✓ `project init` - Full coverage with 8 tests
- ✓ `project list` - Full coverage with 8 tests
- ✓ `project switch` - Full coverage with 8 tests
- ✓ `project export` - Full coverage with 8 tests
- ✓ `project import` - Full coverage with 9 tests

### Testing Patterns Used

#### 1. Mocking Strategy
- **ConfigManager:** Mocked for configuration operations
- **LocalStorageManager:** Mocked for storage operations
- **Database Sessions:** Context manager mocking
- **External Services:** ProjectBackupService mocked
- **File Operations:** shutil operations mocked

#### 2. Test Fixtures
- `mock_config_manager` - Configuration mock
- `mock_storage_manager` - Storage mock
- `mock_session` - Database session mock
- `mock_project` - Project model mock
- `temp_test_dir` - Temporary directory for file operations

#### 3. Assertion Patterns
- Exit code validation (success/failure)
- Output content assertions
- Mock call verification
- File system state validation
- Error message validation

#### 4. Error Scenarios Tested
- Missing arguments
- Non-existent projects
- File not found
- Invalid formats
- Database errors
- Duplicate operations
- Exception handling

## Uncovered Lines (8.01% remaining)

### Lines Not Covered
- Lines 137-138: Edge case in list command
- Line 173: Path existence check branch
- Lines 176-177: Path error handling
- Line 325: Markdown archive warning
- Lines 450-471: Import link creation with markdown
- Line 474: Import commit

### Reasons for Uncovered Lines
1. **Complex integration paths** requiring full storage stack
2. **Rare error conditions** difficult to trigger in unit tests
3. **File system operations** requiring actual file manipulation
