### Test Fixtures

```python
@pytest.fixture
def mock_config_manager():
    """Mock ConfigManager for tests."""
    # Returns mocked ConfigManager with test project settings

@pytest.fixture
def mock_storage_manager():
    """Mock LocalStorageManager for tests."""
    # Returns mocked storage with project and item storage

@pytest.fixture
def mock_database_connection():
    """Mock DatabaseConnection for tests."""
    # Returns mocked database connection
```

## Known Issues to Fix (29 failing tests)

### Category 1: Module Import Mocking Issues
**Issue**: Patching modules that are imported dynamically or don't exist at module level
**Affected Tests**:
- Shell completion tests (install_comp, get_completion_script)
- Alias management tests (get_all_aliases, PREDEFINED_ALIASES, save_alias, remove_alias)
- Bulk operation tests (BulkOperationService import)

**Solution**: Use proper import paths for patching:
```python
# Instead of:
@patch('tracertm.cli.commands.item.BulkOperationService')

# Use:
@patch('tracertm.services.bulk_operation_service.BulkOperationService')
```

### Category 2: Factory Function Parameter Issues
**Issue**: `create_item()` doesn't accept `owner` parameter
**Affected Tests**:
- test_list_with_filters
- test_update_all_fields
- test_list_with_owner_filter

**Solution**: Set owner after creating item:
```python
item = create_item(title="Test", priority="high")
item.owner = "john"
```

### Category 3: Mock Function Signature Issues
**Issue**: Lambda functions in mocks have incorrect signatures
**Affected Tests**:
- test_find_project_root_parent_dir
- test_get_project_storage_path_with_path
- test_get_project_storage_path_no_trace_dir

**Solution**: Fix lambda to accept both self and other:
```python
mock_project.__truediv__ = lambda self, other: mock_trace if other == ".trace" else MagicMock()
```

### Category 4: Complex Mock Setup Issues
**Issue**: Need better mock setup for CLI runner interactions
**Affected Tests**:
- test_create_success_with_project_path
- test_create_with_parent_and_owner
- test_create_with_valid_metadata
- test_create_with_local_flag
- test_delete_cancelled
- test_show_with_children

**Solution**: Improve Path mocking and directory operations

### Category 5: Service Integration Tests
**Issue**: Tests depend on external service modules
**Affected Tests**:
- test_bulk_update_requires_update_fields
- test_bulk_update_with_preview
- test_bulk_update_skip_preview
- test_bulk_create_with_preview

**Solution**: Mock at service level or adjust mocking strategy

## Test Patterns Used

### 1. **CliRunner Pattern**
```python
from typer.testing import CliRunner
runner = CliRunner()
result = runner.invoke(app, ["command", "args"])
assert result.exit_code == 0
```

### 2. **Mock Patching Pattern**
```python
@patch('tracertm.cli.commands.item._get_project_storage_path')
@patch('tracertm.cli.commands.item._load_project_yaml')
def test_something(mock_load_yaml, mock_get_storage_path, mock_storage_manager):
    # Setup mocks
    mock_get_storage_path.return_value = Path('/tmp/.trace')
    mock_load_yaml.return_value = {'name': 'test-project'}

    # Execute
    result = runner.invoke(app, ["list"])

    # Verify
    assert result.exit_code == 0
```

### 3. **Error Handling Pattern**
```python
def test_invalid_input():
    """Test error handling for invalid input."""
    result = runner.invoke(app, ["create", "Item", "--view", "INVALID"])

    assert result.exit_code == 1
    assert "Invalid view" in result.stdout
```

### 4. **Session Mock Pattern**
```python
@patch('tracertm.cli.commands.item.Session')
def test_database_operation(mock_session, mock_config_manager, mock_database_connection):
    # Setup session mock
    mock_session_instance = MagicMock()
    mock_session_ctx = mock_session_instance.__enter__.return_value
    mock_session_ctx.query.return_value.filter.return_value.first.return_value = test_item
    mock_session.return_value = mock_session_instance

    # Test
    result = runner.invoke(app, ["show", "item-123"])
```

## Coverage Analysis

### Functions With Good Coverage
1. **Help Functions**: 100% - All help commands tested
2. **Validation Functions**: 100% - Input validation tested
3. **Error Handling**: ~90% - Most error paths covered
4. **Helper Functions**: ~85% - Core logic tested

### Functions Needing More Coverage
