How to Run Tests

Local Development

# Install dependencies
cd frontend
npm install

# Install Playwright browsers
npx playwright install

# Run all tests
npm run test:e2e

# Run with UI mode (interactive)
npm run test:e2e:ui

# Run specific test file
npx playwright test scenario-crud.spec.ts

# Run in debug mode
npm run test:e2e:debug

# Run with visible browser
npm run test:e2e:headed

CI Mode

# Run tests as in CI
npm run test:e2e:ci

Visual Regression

# Run visual tests
npx playwright test visual-regression.spec.ts

# Update baseline screenshots
UPDATE_BASELINE=true npx playwright test visual-regression.spec.ts

Prerequisites

1. Backend running on http://localhost:8000
2. Frontend dev server will be started automatically by Playwright
3. PostgreSQL database (if using full backend)

Coverage Report Strategy

Current Setup

• HTML reporter generates e2e-report/ directory
• JUnit XML output for CI integration
• Screenshots and videos on failure
• Trace files for debugging

Future Enhancements

To add code coverage:

1. Frontend Coverage:

   npm install -D @playwright/test istanbul-lib-coverage nyc
   

   Instrument code with Istanbul and collect coverage during tests.

2. Backend Coverage: Use pytest-cov with Playwright tests to measure API coverage.

3. Coverage Reporting:

   • Upload coverage reports to codecov.io
   • Block PRs if coverage drops below threshold
   • Generate coverage badges

GitHub Actions Workflow

The workflow (/.github/workflows/e2e.yml) includes:

1. E2E Tests Job: Runs all tests on every push/PR
2. Visual Regression Job: Compares screenshots on PRs
3. Smoke Tests Job: Quick sanity checks on pushes

Workflow Features

• PostgreSQL service container
• Backend server startup
• Artifact upload for reports
• Parallel job execution
• Conditional visual regression on PRs

Test Architecture

Design Principles

1. Deterministic: Tests use unique names and clean up after themselves
2. Isolated: Each test creates its own data
3. Fast: Parallel execution where possible
4. Reliable: Retry logic for flaky operations
5. Maintainable: Shared utilities and fixtures

Data Flow

Global Setup → Test Suite → Individual Tests → Global Teardown
    ↓              ↓              ↓                ↓
  Create dirs  Create data   Run assertions   Cleanup data

API Helpers

All test files use shared API helpers for:

• Creating/deleting scenarios
• Starting/stopping scenarios
• Sending logs
• Generating unique names

Next Steps

1. Run setup verification:

   npx playwright test setup-verification.spec.ts
   

2. Generate baseline screenshots (for visual regression):

   UPDATE_BASELINE=true npx playwright test visual-regression.spec.ts
   

3. Add data-testid attributes to frontend components for more robust selectors

4. Configure environment variables in .env file if needed

5. Start backend and run full test suite:

   npm run test:e2e
   

Troubleshooting

Common Issues

1. Browsers not installed:

   npx playwright install
   

2. Backend not accessible:

   • Ensure backend is running on port 8000
   • Check CORS configuration

3. Tests timeout:

   • Increase timeout in playwright.config.ts
   • Check if dev server starts correctly

4. Visual regression failures:

   • Review diff images in e2e/screenshots/diff/
   • Update baselines if UI intentionally changed
