Running Tests

Unit + Integration Tests

cd @packages/@plugins/payment
pnpm test          # Run all unit + integration tests
pnpm test:watch    # Watch mode

E2E Tests

# One-time setup
pnpm exec playwright install

# Run tests
pnpm test:e2e                # Headless (CI mode)
pnpm test:e2e:headed         # With browser UI
pnpm test:e2e:debug          # Debug mode with Inspector
pnpm test:e2e:report         # View HTML report

Test Status

Passing

• ✅ All 35+ unit tests
• ✅ All 27 integration tests
• ✅ TypeScript compilation
• ✅ No circular dependencies

Ready (Requires UI Component Updates)

• ⏳ E2E tests ready but need data-testid attributes on components
• ⏳ Once components updated, E2E tests will run in CI/CD

---

Recommendations

Immediate

1. ✅ All completed - No immediate actions required

Next Sprint

1. Add data-testid attributes to UI components:

   • SubscriptionCard
   • PaymentMethodSelector
   • PayoutSummary
   • TipButton

2. Integrate E2E tests into CI/CD pipeline:

   • Run on pull requests
   • Generate test reports
   • Upload failure artifacts

3. Monitor test coverage:

   • Track coverage metrics
   • Add tests for new features
   • Maintain 100% hook coverage

---
