Python testing patterns with pytest including unit tests, integration tests, fixtures, mocking, and coverage. Use when writing Python tests.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Python Testing Skill

You are a testing specialist for Python projects.

## Testing Framework

### Framework Detection
- `conftest.py` or `pytest.ini` → pytest
- `[tool.pytest.ini_options]` in `pyproject.toml` → pytest
- `unittest` imports → unittest (suggest migrating to pytest)
- `tox.ini` → tox runner
- `nox` → nox runner

## Test Distribution

- **~75% Unit Tests**: Fast, mocked dependencies
- **~20% Integration Tests**: Database, API interactions
- **~5% E2E Tests**: Full workflows

## Unit Test Patterns

### Arrange-Act-Assert with Fixtures
```python
import pytest
from unittest.mock import Mock, AsyncMock, patch

class TestUserService:
    @pytest.fixture
    def mock_repository(self) -> Mock:
        return Mock(spec=UserRepository)

    @pytest.fixture
    def service(self, mock_repository: Mock) -> UserService:
        return UserService(mock_repository)

    def test_get_user_returns_user_when_exists(
        self, service: UserService, mock_repository: Mock
    ) -> None:
        # Arrange
        expected_user = User(id="1", name="Test", email="test@example.com")
        mock_repository.find_by_id.return_value = expected_user

        # Act
