|
||||
|
||||
- **Unit Tests**: Fast tests that don't require external dependencies
|
||||
- **Integration Tests**: Tests that require database or other external services
|
||||
- **Database Tests**: Tests marked with `@pytest.mark.database`
|
||||
- **Safety Tests**: Tests for safety framework components
|
||||
|
||||
## Running Tests
|
||||
|
||||
### Using the Test Runner
|
||||
|
||||
```bash
|
||||
# Run all tests
|
||||
./run_tests.py
|
||||
|
||||
# Run unit tests only
|
||||
./run_tests.py --type unit
|
||||
|
||||
# Run integration tests only
|
||||
./run_tests.py --type integration
|
||||
|
||||
# Run with coverage
|
||||
./run_tests.py --coverage
|
||||
|
||||
# Run quick tests (unit tests without database)
|
||||
./run_tests.py --quick
|
||||
|
||||
# Run tests with specific markers
|
||||
./run_tests.py --marker safety --marker database
|
||||
|
||||
# Verbose output
|
||||
./run_tests.py --verbose
|
||||
```
|
||||
|
||||
### Using Pytest Directly
|
||||
|
||||
```bash
|
||||
# Run all tests
|
||||
pytest
|
||||
|
||||
# Run unit tests
|
||||
pytest tests/unit/
|
||||
|
||||
# Run integration tests
|
||||
pytest tests/integration/
|
||||
|
||||
# Run tests with specific markers
|
||||
pytest -m "safety and database"
|
||||
|
||||
# Run tests excluding specific markers
|
||||
pytest -m "not database"
|
||||
|
||||
# Run with coverage
|
||||
pytest --cov=src --cov-report=html
|
||||
```
|
||||
|
||||
## Test Configuration
|
||||
|
||||
### Pytest Configuration
|
||||
|
||||
Configuration is in `pytest.ini` at the project root:
|
||||
|
||||
- **Test Discovery**: Files matching `test_*.py`, classes starting with `Test*`, methods starting with `test_*`
|
||||
- **Markers**: Predefined markers for different test types
|
||||
- **Coverage**: Minimum 80% coverage required
|
||||
- **Async Support**: Auto-mode for async tests
|
||||
|
||||
### Test Fixtures
|
||||
|
||||
Shared fixtures are defined in `tests/conftest.py`:
|
||||
|
||||
- `test_db_client`: Database client for integration tests
|
||||
- `mock_pump_data`: Mock pump data
|
||||
- `mock_safety_limits`: Mock safety limits
|
||||
- `mock_station_data`: Mock station data
|
||||
- `mock_pump_plan`: Mock pump plan
|
||||
- `mock_feedback_data`: Mock feedback data
|
||||
|
||||
## Writing Tests
|
||||
|
||||
### Unit Test Guidelines
|
||||
|
||||
1. **Isolation**: Mock external dependencies
|
||||
2. **Speed**: Tests should run quickly
|
||||
3. **Readability**: Clear test names and assertions
|
||||
4. **Coverage**: Test both success and failure cases
|
||||
|
||||
Example:
|
||||
```python
|
||||
@pytest.mark.asyncio
|
||||
async def test_database_connection_success(self, db_client):
|
||||
"""Test successful database connection."""
|
||||
with patch('psycopg2.pool.ThreadedConnectionPool') as mock_pool:
|
||||
mock_pool_instance = Mock()
|
||||
mock_pool.return_value = mock_pool_instance
|
||||
|
||||
await db_client.connect()
|
||||
|
||||
assert db_client.connection_pool is not None
|
||||
mock_pool.assert_called_once()
|
||||
```
|
||||
|
||||
### Integration Test Guidelines
|
||||
|
||||
1. **Markers**: Use `@pytest.mark.integration` and `@pytest.mark.database`
|
||||
2. **Setup**: Use fixtures for test data setup
|
||||
3. **Cleanup**: Ensure proper cleanup after tests
|
||||
4. **Realistic**: Test with realistic data and scenarios
|
||||
|
||||
Example:
|
||||
```python
|
||||
@pytest.mark.integration
|
||||
@pytest.mark.database
|
||||
class TestPhase1Integration:
|
||||
@pytest.mark.asyncio
|
||||
async def test_database_connection_integration(self, integration_db_client):
|
||||
"""Test database connection and basic operations."""
|
||||
assert integration_db_client.health_check() is True
|
||||
```
|
||||
|
||||
## Test Data
|
||||
|
||||
### Mock Data
|
||||
|
||||
Mock data is provided through fixtures for consistent testing:
|
||||
|
||||
- **Pump Data**: Complete pump configuration
|
||||
- **Safety Limits**: Safety constraints and limits
|
||||
- **Station Data**: Pump station metadata
|
||||
- **Pump Plans**: Optimization plans from Calejo Optimize
|
||||
- **Feedback Data**: Real-time pump feedback
|
||||
|
||||
### Database Test Data
|
||||
|
||||
Integration tests use the test database with predefined data:
|
||||
|
||||
- Multiple pump stations with different configurations
|
||||
- Various pump types and control methods
|
||||
- Safety limits for different scenarios
|
||||
- Historical pump plans and feedback
|
||||
|
||||
## Continuous Integration
|
||||
|
||||
### Test Execution in CI
|
||||
|
||||
1. **Unit Tests**: Run on every commit
|
||||
2. **Integration Tests**: Run on main branch and PRs
|
||||
3. **Coverage**: Enforce minimum 80% coverage
|
||||
4. **Safety Tests**: Required for safety-critical components
|
||||
|
||||
### Environment Setup
|
||||
|
||||
Integration tests require:
|
||||
|
||||
- PostgreSQL database with test schema
|
||||
- Test database user with appropriate permissions
|
||||
- Environment variables for database connection
|
||||
|
||||
## Best Practices
|
||||
|
||||
### Test Naming
|
||||
|
||||
- **Files**: `test_<module_name>.py`
|
||||
- **Classes**: `Test<ClassName>`
|
||||
- **Methods**: `test_<scenario>_<expected_behavior>`
|
||||
|
||||
### Assertions
|
||||
|
||||
- Use descriptive assertion messages
|
||||
- Test both positive and negative cases
|
||||
- Verify side effects when appropriate
|
||||
|
||||
### Async Testing
|
||||
|
||||
- Use `@pytest.mark.asyncio` for async tests
|
||||
- Use `pytest_asyncio.fixture` for async fixtures
|
||||
- Handle async context managers properly
|
||||
|
||||
### Mocking
|
||||
|
||||
- Mock external dependencies
|
||||
- Use `unittest.mock.patch` for module-level mocking
|
||||
- Verify mock interactions when necessary
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Common Issues
|
||||
|
||||
1. **Database Connection**: Ensure test database is running
|
||||
2. **Async Tests**: Use proper async fixtures and markers
|
||||
3. **Import Errors**: Check PYTHONPATH and module structure
|
||||
4. **Mock Issues**: Verify mock setup and teardown
|
||||
|
||||
### Debugging
|
||||
|
||||
- Use `pytest -v` for verbose output
|
||||
- Use `pytest --pdb` to drop into debugger on failure
|
||||
- Check test logs for additional information
|
||||
|
||||
## Coverage Reports
|
||||
|
||||
Coverage reports are generated in HTML format:
|
||||
|
||||
- **Location**: `htmlcov/index.html`
|
||||
- **Requirements**: Run with `--coverage` flag
|
||||
- **Minimum**: 80% coverage enforced
|
||||
|
||||
Run `pytest --cov=src --cov-report=html` and open `htmlcov/index.html` in a browser.
