## Brief overview
This rule ensures that I implement comprehensive testing and quality assurance processes for Awwwards-level full-stack websites, covering all aspects from unit testing to user acceptance testing.

## Testing Strategy & Framework Selection
- **Test Pyramid Implementation**: Establish unit tests, integration tests, and end-to-end tests
- **Framework Selection**: Choose appropriate testing frameworks based on technology stack (Jest, Cypress, Playwright, etc.)
- **Test Coverage Goals**: Set minimum coverage thresholds (aim for 80%+ coverage on critical paths)
- **Automated Testing**: Implement automated testing in CI/CD pipeline

## Unit Testing Standards
- **Component Testing**: Test individual components, functions, and modules in isolation
- **Mock Dependencies**: Use proper mocking for external dependencies and APIs
- **Edge Cases**: Cover edge cases, error conditions, and boundary values
- **Performance Testing**: Include performance benchmarks for critical functions

## Integration Testing
- **API Testing**: Test all API endpoints, request/response handling, and error scenarios
- **Database Testing**: Verify database operations, migrations, and data integrity
- **Authentication Testing**: Test login, registration, password reset, and security flows
- **Third-party Integration**: Test external service integrations and fallback mechanisms

## End-to-End Testing
- **User Journeys**: Test complete user workflows from start to finish
- **Cross-browser Testing**: Ensure compatibility across major browsers (Chrome, Firefox, Safari, Edge)
- **Mobile Testing**: Test responsive design and mobile-specific interactions
- **Performance Testing**: Measure page load times, rendering performance, and Core Web Vitals

## Quality Assurance Standards
- **Code Quality**: Implement linting, formatting, and code quality checks
- **Security Testing**: Perform vulnerability scanning and security best practice validation
- **Accessibility Testing**: Ensure WCAG 2.1 AA compliance with automated and manual testing
- **Visual Regression Testing**: Catch unintended visual changes with pixel-perfect comparisons

## Awwwards-Level Quality Validation
- **Performance Benchmarks**: Validate against Awwwards performance standards
- **Visual Polish**: Pixel-perfect implementation of design specifications
- **Interaction Quality**: Smooth animations, transitions, and micro-interactions
- **Cross-device Compatibility**: Test on various screen sizes and devices

## Testing Workflow Integration
- **Pre-commit Hooks**: Run tests before code commits to catch issues early
- **CI/CD Integration**: Automated testing in deployment pipeline
- **Test Reporting**: Generate comprehensive test reports and coverage analysis
- **Bug Tracking**: Integrate with issue tracking systems for defect management

## User Acceptance Testing
- **Staging Environment**: Deploy to staging for final user validation
- **User Feedback**: Collect feedback on usability and functionality
- **Performance Monitoring**: Monitor real-world performance and user behavior
- **Final Sign-off**: Ensure all requirements are met before production deployment
