## Test Execution

### Collect Tests
```bash
# All retention tests
pytest tests/unit/test_daily_quests.py tests/unit/test_daily_rewards.py tests/unit/test_achievements.py tests/unit/test_tutorial.py --collect-only

# Individual files
pytest tests/unit/test_daily_quests.py --collect-only    # 10 tests

## Testing Patterns Used

### 1. Arrange-Act-Assert (AAA) Pattern
All tests follow the clear AAA structure:
```python
def test_example():
    # Arrange - Set up test data and mocks
    player = create_test_player()
    mock_db.return_value = expected_data

    # Act - Execute the function under test
    result = function_under_test(player)

    # Assert - Verify the results
    assert result['success'] is True
```

### 2. Fixtures
- `adult_player` - Adult character for quest/reward tests
- `newborn_player` - Newborn character for tutorial tests
- `mock_db_connection` - Mock database connections
- `mock_db_fetch_*` - Mock database fetch operations

### 3. Mocking Strategy
- Database connections mocked with `MagicMock()`
- Async database queries mocked with `AsyncMock()`
- External dependencies mocked to avoid side effects
- Circular imports resolved with `sys.modules` mocking

### 4. Async Testing
- Uses `@pytest.mark.asyncio` decorator for async tests
- Properly handles async/await patterns
- Mocks async database operations

- AsyncMock for async database operations
- pytest-asyncio integration

### 3. Import Handling

## Integration with Existing Test Suite

These tests integrate seamlessly with the existing test infrastructure:

- ✅ Uses existing `conftest.py` configuration
- ✅ Follows existing test patterns (see `test_event_base.py`)
- ✅ Compatible with pytest configuration in `pytest.ini`
- ✅ Uses established mocking patterns
- ✅ Follows project coding standards

---

## Next Steps

1. **Run Tests**: Execute the test suite to verify functionality
2. **Generate Coverage**: Run with `--cov` to measure coverage
3. **Integration**: Integrate into CI/CD pipeline
4. **Expand**: Add more edge case tests as needed
5. **Maintenance**: Update tests as retention systems evolve
