## Key Test Features

### Testing Patterns
- **Arrange-Act-Assert** pattern throughout
- **Boundary testing** for age transitions (5, 13, 18, 21, 65 years)
- **State verification** for energy, mood, money calculations
- **Integration testing** for multi-system interactions

### Mock Objects
- Uses `SimpleNamespace` for lightweight mocks
- Mocks for jobs, activities, habits, relationships
- No database dependencies required

### Fixtures
- Player factories for all age groups
- Consistent test data across tests
- Reusable factory functions

### Coverage Focus
- ✅ Age calculation formulas (ageHours → ageDays → ageYears)
- ✅ Birthday events and age transitions
- ✅ Energy depletion from activities
- ✅ Mood state transitions (6 moods: Calm, Stressed, Exhausted, Fulfilled, Depressed, Happy)
- ✅ Financial systems (normal, frugal, extravagant spending)
- ✅ Event deduplication via sets
- ✅ One-time event execution and cleanup
- ✅ Relationship affinity decay
- ✅ Stat boundaries and edge cases
