Testing Guide

Overview​

This guide covers the comprehensive testing strategy for the Toto platform, including unit tests, integration tests, and end-to-end testing with Playwright.

🎯 Testing Strategy​

Unit Testing: Jest with 85%+ coverage​

  • Component testing with React Testing Library
  • API endpoint testing
  • Utility function testing
  • Mocking Firebase services

Integration Testing: API and database testing​

  • Database operations
  • Authentication flows
  • Cross-service communication

E2E Testing: Complete user workflow validation​

  • User registration and authentication
  • Case management workflows
  • Donation processing
  • AI chat interactions

AI Testing: Conversation accuracy and intent recognition​

  • Intent detection accuracy
  • Response quality validation
  • Multi-language support testing

Performance Testing: Load and stress testing​

  • Core Web Vitals measurement
  • Load time tracking
  • Memory usage monitoring

🛠️ E2E Testing with Playwright​

Setup​

  1. Install Playwright browsers:

    npm run test:e2e:install

  2. Start the development server:

    npm run dev

  3. Run tests in another terminal:

    npm run test:e2e

Available Scripts​

  • npm run test:e2e - Run all E2E tests
  • npm run test:e2e:ui - Run tests with interactive UI
  • npm run test:e2e:headed - Run tests in headed mode (visible browser)
  • npm run test:e2e:debug - Run tests in debug mode
  • npm run test:e2e:report - Show test report
  • npm run test:e2e:install - Install Playwright browsers

Test Coverage​

Authentication Flow (auth.spec.ts)​

  • ✅ Sign-in page display
  • ✅ Form validation (email, password)
  • ✅ Navigation to sign-up
  • ✅ Successful login
  • ✅ Login error handling

Case Management (cases.spec.ts)​

  • ✅ Cases list display
  • ✅ Create new case
  • ✅ Edit existing case
  • ✅ Delete case
  • ✅ Filter cases by status

Donation Flow (donations.spec.ts)​

  • ✅ Donation form display
  • ✅ Amount validation
  • ✅ Successful donation processing
  • ✅ Payment error handling
  • ✅ Donation history display
  • ✅ Filter donations by status

AI Chat Integration (ai-chat.spec.ts)​

  • ✅ Chat interface display
  • ✅ Send message and receive response
  • ✅ Streaming responses
  • ✅ Intent suggestions
  • ✅ Disambiguation handling
  • ✅ Error handling
  • ✅ Conversation history

Test Utilities​

The test-helpers.ts file provides utilities for:

  • Mocking authentication
  • Mocking API responses
  • Form filling and submission
  • File uploads
  • Element waiting and checking
  • Screenshot capture
  • Performance metrics
  • Accessibility checks

Configuration​

Tests are configured in playwright.config.ts:

  • Multiple browser support (Chrome, Firefox, Safari)
  • Mobile device testing
  • Screenshot and video capture on failure
  • Global setup and teardown
  • Test timeouts and retries

🎯 Best Practices​

  1. Use data-testid attributes for reliable element selection
  2. Mock API responses to ensure consistent test behavior
  3. Clean up after tests to avoid test interference
  4. Use page object pattern for complex interactions
  5. Test both happy path and error scenarios
  6. Include accessibility checks where relevant
  7. Take screenshots for debugging failed tests

🐛 Debugging​

  1. Run in headed mode to see the browser:

    npm run test:e2e:headed

  2. Use debug mode to step through tests:

    npm run test:e2e:debug

  3. Check test reports for detailed failure information:

    npm run test:e2e:report

  4. View screenshots in test-results/screenshots/ directory

🚀 CI/CD Integration​

Tests can be integrated into CI/CD pipelines:

# Example GitHub Actions workflow
- name: Run E2E tests
  run: |
    npm run test:e2e:install
    npm run test:e2e

📊 Performance Testing​

The test utilities include performance monitoring:

  • Core Web Vitals measurement
  • Load time tracking
  • Memory usage monitoring
  • Network request analysis

♿ Accessibility Testing​

Basic accessibility checks are included:

  • Alt text validation for images
  • Form label verification
  • ARIA attribute checking

🔧 Maintenance​

  • Update tests when UI changes
  • Add new test cases for new features
  • Review and update mocks regularly
  • Keep test data current and realistic

📋 Quality Standards​

  • TypeScript: Strict mode enabled
  • Code Review: All changes reviewed
  • Accessibility: WCAG 2.1 AA compliance
  • Performance: Lighthouse score >90
