# Testing Standards
|
|
|
|
## Test Organization
|
|
- **Test directory**: [test/](mdc:test/) - All test files
|
|
- **Unit tests**: Test individual components in isolation
|
|
- **Integration tests**: Test component interactions
|
|
- **Hardware tests**: Validate on Raspberry Pi with actual LED matrix
|
|
|
|
## Testing Principles
|
|
- **Test behavior, not implementation**: Focus on what the code does, not how
|
|
- **Mock external dependencies**: Use mocks for APIs, display managers, cache
|
|
- **Test edge cases**: Empty data, API failures, configuration errors
|
|
- **Pi-specific testing**: Validate hardware integration
|
|
|
|
## Test Structure
|
|
```python
|
|
def test_manager_initialization():
|
|
"""Test that manager initializes with valid config"""
|
|
config = {"sport_scoreboard": {"enabled": True}}
|
|
manager = ManagerClass(config, mock_display, mock_cache)
|
|
assert manager.enabled == True
|
|
|
|
def test_api_failure_handling():
|
|
"""Test graceful handling of API failures"""
|
|
# Test that system continues when API fails
|
|
# Verify fallback to cached data
|
|
# Check appropriate error logging
|
|
```
|
|
|
|
## Mock Patterns
|
|
- **Display Manager**: Mock for testing without hardware
|
|
- **Cache Manager**: Mock for testing data persistence
|
|
- **API responses**: Mock for consistent test data
|
|
- **Configuration**: Use test-specific configs
|
|
|
|
## Test Categories
|
|
- **Unit tests**: Individual manager methods
|
|
- **Integration tests**: Manager interactions with services
|
|
- **Configuration tests**: Validate config loading and validation
|
|
- **Error handling tests**: API failures, invalid data, edge cases
|
|
|
|
## Testing Best Practices
|
|
- **Descriptive names**: Test names should explain what they test
|
|
- **Single responsibility**: Each test should verify one thing
|
|
- **Independent tests**: Tests should not depend on each other
|
|
- **Clean setup/teardown**: Reset state between tests
|
|
- **Pi compatibility**: Ensure tests work in Pi environment |
