- ✓ scheduleComplete() - Schedule completion checking
- ✓ setLikesDislikes() - Interest/dislike generation

## Test Categories (as per TESTING_PLAN.md Section 3.4)

| Category | Required Tests | Implemented Tests | Status |
|----------|----------------|-------------------|--------|
| Age Updates | 5 | 8 | ✓ Exceeded |
| Energy Calculations | 6 | 7 | ✓ Exceeded |
| Mood & Happiness | 6 | 7 | ✓ Exceeded |
| Finances | 3 | 5 | ✓ Exceeded |
| Event Checking | 5 | 5 | ✓ Complete |

## Test Features

### Fixtures Used
- Player factories for different age groups
- SimpleNamespace for mock objects
- datetime manipulation for time-based tests

### Test Patterns
- Arrange-Act-Assert pattern
- Boundary testing (age transitions at 5, 13, 18, 21, 65)
- State verification (energy, mood, money)
- Integration testing (multiple systems together)

### Coverage Focus
- ✓ Age calculation formulas (ageHours → ageDays → ageYears)
- ✓ Birthday events and age transitions
- ✓ Energy depletion from activities
- ✓ Mood changes based on stats
- ✓ Financial systems (salary, spending habits, part-time)
- ✓ Event deduplication
- ✓ One-time event execution and cleanup
- ✓ Relationship affinity decay
- ✓ Stat boundaries and edge cases

## Running the Tests

```bash
# Run all stats manager tests
pytest tests/unit/test_stats_manager.py -v

# Run specific test class
pytest tests/unit/test_stats_manager.py::TestAgeUpdates -v

# Run specific test
pytest tests/unit/test_stats_manager.py::TestEnergyCalculations::test_get_peak_energy_child -v

# Run with coverage
pytest tests/unit/test_stats_manager.py --cov=stats.stats_manager --cov-report=html
```

## Dependencies Required

```txt
pytest>=7.4.3
pytest-cov>=4.1.0
```

## Notes

- Tests are self-contained and don't require database
- Mock objects used for complex dependencies (jobs, activities, habits)
- Player factories provide consistent test data
- Tests follow existing patterns from test_stats.py
- All imports from `stats.stats_manager` as per refactored structure
- Integration tests verify multiple systems work together

## Alignment with TESTING_PLAN.md

This implementation follows Section 3.4 of TESTING_PLAN.md:
- ✓ 40-50 test cases (44 implemented)
- ✓ All required test categories covered
- ✓ Uses player fixtures
- ✓ Tests calculation formulas
- ✓ Verifies stat boundaries
- ✓ Imports from ws/stats/stats_manager.py
- ✓ Priority P1 (Week 3-4) as specified

## Next Steps

1. Install pytest: `pip install pytest pytest-cov`
2. Run tests: `pytest tests/unit/test_stats_manager.py -v`
3. Check coverage: `pytest tests/unit/test_stats_manager.py --cov=stats.stats_manager`
4. Add more edge case tests if coverage < 90%
5. Integrate with CI/CD pipeline
