### e2e-critical-001: Fix critical E2E test failures (27/35 failing)
**File Location**: `tests/e2e/` (multiple test files)
**Current State**: 77% test failure rate - fundamental application issues
**Impact**: Critical - Application may not be functioning correctly
**Estimated Effort**: 24 hours

**Specific Tasks**:
- [ ] Debug homepage loading issues (empty title detected)
- [ ] Fix product display elements not found
- [ ] Resolve cart navigation failures
- [ ] Fix checkout flow redirection issues
- [ ] Resolve cart page content loading problems
- [ ] Install missing WebKit/Safari browser dependencies

// Current failing tests
❌ Homepage title verification (title is empty "")
❌ Product display elements not found on homepage
❌ Cart navigation not working
❌ Checkout flow redirection failing
❌ Cart page content not loading
❌ Mobile viewport testing partially working
```

**Immediate Debugging Steps**:
```bash
# 1. Check application startup
pnpm run dev

const testUsers = {
  standardUser: { email: 'test@example.com', password: 'test123' },
  premiumUser: { email: 'premium@example.com', password: 'premium123' },
  adminUser: { email: 'admin@example.com', password: 'admin123' }
};

// Test products needed
const testProducts = {
  simpleProduct: { name: 'Test T-Shirt', price: 19.99 },
  variableProduct: { name: 'Test Hoodie', variants: ['S', 'M', 'L'] },
  digitalProduct: { name: 'Test Ebook', type: 'digital' }
};
```

### Test Environment Setup
```bash
# Database seeding
pnpm run seed:test-data

# Redis setup
docker run -d -p 6379:6379 redis

# Stripe test configuration
STRIPE_SECRET_KEY=sk_test_...
STRIPE_WEBHOOK_SECRET=whsec_...
```

## Success Metrics

### E2E Test Success Targets
- **Test Success Rate**: 95%+ (from current 23%)
- **Test Coverage**: 80%+ of user journeys
- **Browser Compatibility**: 100% across supported browsers
- **Mobile Testing**: 100% core functionality on mobile
- **Test Execution Time**: <10 minutes for full suite

### Quality Gates
- No critical E2E test failures in production
- All major user journeys tested
- Payment flows validated end-to-end
- Authentication flows tested across scenarios

---

## Tools and Configuration

### Required Tools
- **Playwright**: E2E testing framework (already configured)
- **Test Containers**: For database and Redis
- **Mock Service Worker**: For API mocking when needed
- **Lighthouse CI**: For performance testing integration

### Configuration Improvements
```typescript
// Enhanced playwright.config.ts
export default defineConfig({
  webServer: {
    command: 'pnpm run dev',
    url: 'http://localhost:3000',
    reuseExistingServer: !process.env.CI,
    timeout: 120 * 1000,
  },
  projects: [
    { name: 'chromium', use: { ...devices['Desktop Chrome'] } },
    { name: 'firefox', use: { ...devices['Desktop Firefox'] } },
    { name: 'webkit', use: { ...devices['Desktop Safari'] } },
    { name: 'Mobile Chrome', use: { ...devices['Pixel 5'] } },
    { name: 'Mobile Safari', use: { ...devices['iPhone 12'] } },
  ],
  timeout: 30 * 1000,
  retries: process.env.CI ? 2 : 0,
});
```

This comprehensive E2E testing plan addresses the critical 77% failure rate and ensures all core e-commerce functionality is properly validated across devices and browsers.
