- `testClassrooms` object with test classroom data

**Example:**
```typescript
export const testUsers = {
  student: {
    email: 'student@test.gamilit.com',
    password: 'TestStudent123!',
    role: 'student',
    expectedDashboard: '/student/dashboard',
  },

- `loginAsAdmin(page)` - Quick admin login
- `logout(page)` - Logout function
- `isLoggedIn(page)` - Check auth status
- `setupAuthState(page, role)` - Fast auth setup

**Example:**
```typescript
import { loginAsStudent } from './fixtures/auth-helpers';

test('student test', async ({ page }) => {
  await loginAsStudent(page);
  // User is now logged in and on dashboard
});
```

---

### 3.3 Page Helpers (helpers/page-helpers.ts)

**Purpose:** Reusable page interaction functions

**Functions:**

## 8. Known Limitations and Future Work

### Current Limitations
1. **Test Data Dependency** - Tests require pre-seeded database
2. **No Visual Regression** - Screenshots not yet compared
3. **Limited Mobile Testing** - Only viewport testing, no real devices
4. **No Performance Tests** - Load times not measured

### Recommended Next Steps
1. **Add Visual Regression Testing**
   - Use Playwright's screenshot comparison
   - Create baseline images
   - Detect UI regressions

2. **Implement Test Data Factories**
   - Create dynamic test data
   - Reduce database dependency
   - Enable parallel test execution

3. **Add Performance Benchmarks**
   - Measure page load times
   - Track exercise completion time
   - Monitor API response times

4. **Expand Mobile Testing**
   - Test on real mobile devices (BrowserStack/Sauce Labs)
   - Test touch gestures
   - Test responsive breakpoints

5. **Add Accessibility Tests**
   - Integrate axe-core
   - Test keyboard navigation
   - Test screen reader compatibility
