## Key Features

### ✅ Soft Assertions
Tests gracefully handle incomplete features:
```typescript
const button = page.getByRole('button', { name: /create/i })
if (await button.isVisible({ timeout: 2000 }).catch(() => false)) {
  // Test if available
} else {
  console.log('Feature not available - skipping')
}
```

### ✅ MSW Integration
All tests use Mock Service Worker:
- No backend server required
- Consistent test data
- Fast execution (each test < 2 seconds)
- Offline testing capability

### ✅ Comprehensive Error Handling
- Screenshots on failure
- Videos of failed tests
- Trace files for debugging
- Clear error messages with context

### ✅ Reusable Helpers
Eliminates code duplication:
```typescript
// Instead of repeating this in every test:
const createBtn = page.getByRole('button', { name: /create/i })
await createBtn.click()
await page.waitForTimeout(500)
const nameInput = page.getByLabel(/name/i)
await nameInput.fill(name)

// Use helper:
const success = await createProject(page, { name })
```

### ✅ Easy Debugging
Multiple debugging options:
```bash
bun run test:e2e:ui        # Interactive debugging
bun run test:e2e:headed    # See browser
bun run test:e2e:debug     # Step through code
bun run test:e2e:report    # View artifacts
```

---

## How to Use

### Quick Start
```bash
cd frontend/apps/web

# Run all critical path tests
bun run test:e2e -- critical-path.spec.ts

# Expected output:
# 19 passed (9.8s)
```

### Interactive Development
```bash
# Best for developing and debugging
bun run test:e2e:ui -- critical-path.spec.ts

# See browser window
bun run test:e2e:headed -- critical-path.spec.ts

# Step-by-step debugging
bun run test:e2e:debug -- critical-path.spec.ts
```

### Run Specific Tests
```bash
# By file
bun run test:e2e -- critical-path.spec.ts

# By name pattern
bun run test:e2e -- critical-path.spec.ts -g "project creation"

# Single test
bun run test:e2e -- critical-path.spec.ts -g "should create a new item"
```

### View Reports
```bash
bun run test:e2e:report
# Opens: playwright-report/index.html
# Shows: screenshots, videos, traces for each test
```

## Test Examples

### Example 1: Using Helpers
```typescript
import {
  navigateToProjects,
  createProject,
  generateProject
} from './critical-path-helpers'

test('create project', async ({ page }) => {
  // Navigate
  await navigateToProjects(page)

  // Generate unique test data
  const project = await generateProject({
    name: 'My Project',
    description: 'Test'
  })

  // Create
  const success = await createProject(page, project)

  // Verify
  expect(success).toBe(true)
})
```

### Example 2: Search and Filter
```typescript
import {
  navigateToItems,
  searchItems,
  filterByStatus,
  filterByType
} from './critical-path-helpers'

test('search and filter items', async ({ page }) => {
  await navigateToItems(page)

  // Search
  const count = await searchItems(page, 'authentication')
  expect(count).toBeGreaterThan(0)

  // Filter by status
  await filterByStatus(page, 'Completed')

  // Filter by type
  await filterByType(page, 'Requirement')
})
```

### Example 3: Navigation
```typescript
import {
  navigateToDashboard,
  navigateToProjects,
  navigateToItems
} from './critical-path-helpers'

test('navigation flow', async ({ page }) => {
  await navigateToDashboard(page)
  await expect(page).toHaveURL('/')

  await navigateToProjects(page)
  await expect(page).toHaveURL('/projects')

  await navigateToItems(page)
  await expect(page).toHaveURL('/items')
})
```

---

## Maintenance and Support

### Regular Maintenance
- **Weekly**: Review failed tests, check for flaky tests
- **Monthly**: Run full E2E suite, update selectors if UI changes
- **Quarterly**: Review test coverage, refactor helpers

### When UI Changes
1. Run tests to identify broken selectors
2. Use Playwright Inspector to find new selectors
3. Update test files and helpers
4. Verify tests pass locally
5. Commit changes

### Adding New Tests
1. Identify critical user flow
2. Write test using helpers from `critical-path-helpers.ts`
3. Run in UI mode to debug
4. Verify test passes locally
5. Commit with feature

---

## Troubleshooting Guide

### "Element not found"
Solution: Run in UI mode to see actual DOM
```bash
bun run test:e2e:ui -- critical-path.spec.ts -g "test name"
```

### "Navigation timeout"
Solution: Ensure dev server is running
```bash
bun run dev  # In another terminal
```

### "Tests are slow"
Solution: Check for unnecessary waits
```typescript
// ❌ Avoid
await page.waitForTimeout(5000)

// ✅ Use
await page.waitForLoadState('networkidle')
```

### "Flaky tests"
Solution: Add explicit waits
```typescript
await page.waitForLoadState('networkidle')
await page.waitForTimeout(500)
```
