   - Help text generation
   - Output formatting
   - Integration workflows

## Testing Techniques Used

1. **AsyncMock** - For mocking async methods
2. **MagicMock** - For mocking complex objects
3. **patch** - For mocking stdout and module imports
4. **StringIO** - For capturing output
5. **CliRunner** - For testing Typer CLI commands
6. **pytest.mark.asyncio** - For async test functions
7. **pytest.mark.unit** - For test categorization

## Code Quality

- **Type hints**: All test functions use proper type annotations
- **Docstrings**: Every test has clear documentation
- **Organization**: Tests grouped by functionality in logical classes
- **Comprehensive coverage**: Tests cover happy path, edge cases, and error conditions
- **Mocking**: Proper mocking of dependencies to ensure isolated tests
