## Test Implementation Highlights

### Real-World Code Examples

All tests use production-like code patterns:
- React functional components with hooks
- TypeScript interfaces and generics
- Redux reducer patterns
- REST API clients
- Security vulnerabilities from OWASP Top 10
- Complex business logic
- Circular module dependencies

### Comprehensive Edge Case Coverage

- Empty/null inputs
- Malformed data and invalid formats
- Boundary conditions (0%, 100%, thresholds)
- Large datasets (10+ files)
- Special characters and Unicode
- Long file paths and names
- Dynamic imports

### TDD Methodology

- Red: Write failing test
- Green: Minimal code to pass
- Refactor: Improve while maintaining test passing

### Error Handling

- Non-existent files
- Non-TypeScript files
- Malformed code
- Missing data
- Timeout scenarios
