## Key Patterns Established

### 1. Database Testing Pattern
```python
@pytest.fixture
def db_session():
    engine = create_engine("sqlite:///:memory:")
    Base.metadata.create_all(engine)
    session = SessionLocal(bind=engine)
    yield session
    session.close()
```

### 2. Storage Layer Mocking Pattern (Phase 10)
```python
@pytest.fixture
def mock_storage_manager():
    with patch('tracertm.cli.storage_manager.LocalStorageManager') as mock:
        session = MagicMock()
        mock.return_value.get_session.return_value.__enter__.return_value = session
        yield mock
```

### 3. CLI Command Pattern
```python
from tracertm.cli.storage_manager import LocalStorageManager

@app.command()
def my_command():
    storage = LocalStorageManager()
    with storage.get_session() as session:
        # Implementation
```

### 4. Test Isolation Pattern
```python
@pytest.fixture(autouse=True)
def isolated_cli_environment(tmp_path, monkeypatch):
    monkeypatch.chdir(tmp_path)
    yield
```

### 5. Async Configuration Pattern
```python
# conftest.py
pytest_plugins = ["pytest_asyncio"]

# pyproject.toml
[tool.pytest.ini_options]
asyncio_mode = "auto"
```
