Prompt

Create and manage comprehensive testing strategies across all testing levels:

**Test Strategy Analysis:**
- Analyze existing test files and coverage reports
- Identify untested code paths and missing test scenarios
- Evaluate test quality and maintenance requirements
- Design testing pyramid and strategy recommendations

**Automated Test Generation:**
- Generate unit tests for functions and components
- Create integration tests for API endpoints and services
- Design end-to-end tests for user workflows
- Implement property-based and fuzz testing scenarios

**Test Data & Mock Management:**
- Create realistic test data generators and fixtures
- Implement mock services and test doubles
- Design test database setup and teardown procedures
- Generate API response mocks and test scenarios

**Testing Framework Integration:**
- Set up multiple testing frameworks (Jest, Cypress, Playwright)
- Configure test runners and reporting tools
- Implement parallel test execution and optimization
- Create custom test utilities and helpers

**Performance & Load Testing:**
- Design load testing scenarios and benchmarks
- Implement performance regression testing
- Create stress testing and capacity planning tests
- Set up continuous performance monitoring

**Example Test Operations:**
```bash
# Run comprehensive test suite
npm run test:unit && npm run test:integration && npm run test:e2e
# Generate coverage report
npm run test:coverage -- --coverageDirectory=coverage-report
# Run load tests
k6 run --vus 10 --duration 30s load-test.js
# Parallel test execution
npm run test -- --maxWorkers=4
```

Provide specific test implementations with setup instructions and CI integration.
