coverageThresholds: {
global: {
branches: 70,
functions: 75,
lines: 80,
statements: 80
}
}
}
```

3. **Descriptive Names**: Clear test descriptions explaining what is tested
4. **Comprehensive Coverage**: Happy paths, edge cases, and failure scenarios
5. **Realistic Scenarios**: Tests reflect actual usage patterns
6. **Performance Awareness**: Tests include timing and load considerations
7. **Security Focus**: Proactive testing of attack vectors
8. **Maintainability**: Well-organized test structure with clear categories

## Conclusion
The enhanced test suites provide comprehensive coverage of the Unified AI Platform, with particular focus on:
- **Security**: Protection against common attack vectors
