 # Testing Strategy
 
 ## Overview
+
 This project follows a pragmatic testing approach that balances code quality with development velocity.
 
 ## Current Coverage Status
+
 - **Overall**: ~16% coverage
 - **Critical Path** (optimizer.ts): ~90% coverage ✅
 - **Hooks**: ~97% coverage ✅

 ## Testing Philosophy
 
 ### 1. Progressive Coverage
+
 - Start with realistic thresholds (current: 13-16%)
 - Gradually increase as the codebase matures
 - Target: 50% overall coverage by v2.0
 
 ### 2. Priority-Based Testing
+
 **High Priority** (Must have tests):
+
 - Business logic (optimizers, algorithms)
 - Data transformations
 - Utility functions
 - Custom hooks
 
 **Medium Priority** (Nice to have):
+
 - Complex UI components
 - API integrations
 - State management
 
 **Low Priority** (Can rely on manual/E2E):
+
 - Simple UI components
 - Static pages
 - Style-only components
 
 ### 3. Test Types
 
 #### Unit Tests (Current Focus)
+
 ```bash
 npm test                 # Run all tests
 npm test -- --coverage   # With coverage report
 npm test -- --watch      # Watch mode for TDD
 ```
 
 #### Integration Tests (Future)
+
 - Test complete user flows
 - Verify optimizer outputs with real data
 - API endpoint testing
 
 #### E2E Tests (Future)
+
 - Critical user journeys
 - Cross-browser compatibility
 - Performance benchmarks

 ### Critical Files
+
 - `lib/optimizer.ts`: 85%+ coverage required
 - `lib/hooks/*.ts`: 95%+ coverage required
 - New utility functions: 80%+ coverage expected
 
 ## Adding Tests
 
 ### For New Features
+
 1. Write tests BEFORE implementation (TDD)
 2. Ensure critical paths have tests
 3. Add integration tests for complex features
 
 ### For Bug Fixes
+
 1. Write a failing test that reproduces the bug
 2. Fix the bug
 3. Ensure test passes
 
 ### For UI Components
+
 1. Focus on behavior, not implementation
 2. Test user interactions
 3. Verify accessibility
 
 ## CI/CD Integration
 
 Tests run automatically on:
+
 - Every push to main
 - All pull requests
 - Pre-deployment checks
 
 ### Handling Test Failures
+
 1. **Coverage below threshold**: Add tests or adjust thresholds with justification
 2. **Test failures**: Fix immediately, don't skip tests
 3. **Flaky tests**: Investigate root cause, don't ignore
