Running E2E Tests

# Run all E2E tests (headless, all browsers)
npm run test:e2e

# Run with visible browser (debugging)
npm run test:e2e:headed

# Run specific test file
npx playwright test tests/e2e/workflows/gallery-browsing.spec.ts

# Run tests for specific browser
npx playwright test --project="Desktop Chrome"

# Run mobile-only tests
npx playwright test --project="Mobile Chrome" --project="Mobile Safari"

# View test report
npx playwright show-report

Safari E2E Testing

Safari Smoke Tests run in CI (optimized subset), Full Safari Suite available locally.

CI Strategy (Issue #211 Optimization):

After 15+ hours of investigation (Issue #209), full Safari E2E suite consistently times out at 40min (vs 5min Chrome baseline). Safari test execution is inherently ~8x slower due to WebKit/JavaScriptCore performance characteristics.

Solution: Safari Smoke Test Subset (Ultra-Minimal)

• In CI: Safari Smoke tests (8 tests from smoke-test.spec.ts only, ~5-7min target)
• Coverage: Basic app health validation (no gallery tests due to Safari timeout issues)
• Test files: smoke-test.spec.ts (homepage, contact, navigation, JS errors)
• Gallery limitation: Safari/WebKit takes >30s to load gallery (Issue #236 tracks optimization)
• Retry optimization: 1 retry (vs 2 for Chrome) to reduce execution time
• Platform: Ubuntu 22.04 with WebKit (cost-effective, stable)

Running Safari Tests Locally:

# Run Safari Smoke tests (same as CI)
npx playwright test --project="Safari Smoke"

# Run FULL Safari E2E suite (local only, ~40min)
npx playwright test --project="Desktop Safari"

# Run Safari tests with visible browser (debugging)
npx playwright test --project="Desktop Safari" --headed

# Run specific Safari test
npx playwright test tests/e2e/workflows/gallery-browsing.spec.ts --project="Desktop Safari"

# Run mobile Safari tests (local only)
npx playwright test --project="Mobile Safari"
npx playwright test --project="Mobile Safari Landscape"

Browser Coverage:

• Desktop Chrome: 65% market share (CI - full E2E suite)
• Mobile Chrome: 40% mobile market share (CI - full E2E suite)
• Safari Smoke: 20% market share (CI - ultra-minimal: basic health only)
• Total CI coverage: 85%+ browsers (Safari has limited test coverage due to gallery timeout issue)

Requirements for Full Local Safari Testing:

• macOS machine (native Safari/WebKit support)
• Playwright installed with WebKit: npx playwright install webkit

Context: Portfolio site with Safari ~20% market share. Safari Smoke tests in CI provide Safari validation while maintaining fast CI pipeline. Full Safari suite available locally for comprehensive testing.

Test Environment Setup

Prerequisites:

• Node.js 18+
• Playwright browsers installed: npx playwright install
• Dev server running (automatically started by tests)

Environment Variables:

E2E_BASE_URL=http://localhost:3000  # Optional, defaults to localhost:3000

Debugging E2E Tests

Visual Debugging:

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

# Run with Playwright Inspector
npx playwright test --debug

# Run specific test with inspector
npx playwright test tests/e2e/workflows/smoke-test.spec.ts --debug

Failure Artifacts:

• Screenshots: test-results/[test-name]/test-failed-1.png
• Videos: test-results/[test-name]/video.webm
• Traces: test-results/[test-name]/trace.zip (view with npx playwright show-trace)

Troubleshooting

Tests fail with "page.goto: net::ERR_CONNECTION_REFUSED":

• Ensure dev server is running: npm run dev
• Or let Playwright auto-start: config includes webServer setup

Tests timeout on slow machines:

• Increase timeout in playwright.config.ts
• Run fewer browsers: npx playwright test --project="Desktop Chrome"

Mobile tests fail:

• Verify mobile browsers installed: npx playwright install
• Check viewport configuration in test files

CI/CD Integration

E2E tests run automatically on GitHub Actions for all pull requests:

Workflow Configuration:

• Trigger: Automatically runs on all non-draft PRs to master
• Browser Matrix: Tests run in parallel across Desktop Chrome, Mobile Chrome, and Desktop Safari
• Efficiency: Only installs required browser binaries per project (saves CI time)
• Failure Handling: fail-fast: false ensures all browser tests complete even if one fails

Artifacts & Debugging:

• Test Results: JSON reports uploaded for all test runs (7-day retention)
• HTML Reports: Full Playwright HTML reports available for review
• Screenshots: Captured on test failures for visual debugging
• Videos: Test execution videos recorded on failures
• Traces: Full execution traces with timeline, network, and console logs

Draft PR Behavior:

• Draft PRs skip E2E tests by default to save CI resources
• Add the test-e2e label to any draft PR to force E2E test execution

Viewing Results:

• Check the "E2E Tests" workflow in the PR's Checks tab
• Download artifacts from the workflow run for local inspection
• View the Playwright HTML report artifact for detailed test results

Performance Testing Strategy

Fast TDD-compliant tests that document and validate our 83% bundle optimization:

# Performance validation (runs in seconds)

🎨 Customization

Styling System

The site uses Tailwind CSS with custom design tokens:

:root {
  --color-primary: #333;
  --color-secondary: #666;
  --font-size-base: 16px;
  --spacing-md: 16px;
  --transition-normal: 0.3s ease;
}

Content Management

All textile projects are managed through Sanity CMS:

// Query example for textile designs
const designs = await client.fetch(`
  *[_type == "textileDesign"] | order(_createdAt desc) {
    title,
    description,
    images,
    techniques,
    materials,
    year
  }
`)

🔄 Development Workflow

Feature Development

1. Create feature branch from main
2. Follow TDD approach (Test-Driven Development)
3. Run quality checks before commit
4. Create PR with comprehensive description
5. Merge only after all checks pass

Quality Standards

• All new features require tests
• TypeScript strict mode enforced
• ESLint and Prettier formatting
• Pre-commit hooks prevent regressions
• Performance budgets maintained

📞 Support

For questions about portfolio features or customization:

• Review the comprehensive inline documentation
• Check component tests for usage examples
