## Testing Integration

The pages are fully compatible with the E2E tests in `e2e/auth-advanced.spec.ts`:

### Selectors Used by Tests:

- `input[name="email"]` - Email input
- `input[name="password"]` - Password input
- `input[name="name"]` - Name input (registration)
- `input[name="confirmPassword"]` - Confirm password input
- `input[name="acceptTerms"]` - Terms checkbox
- `input[name="rememberMe"]` - Remember me checkbox
- `input[name="newPassword"]` - New password input (reset)
- `button[type="submit"]` - Submit buttons
- `[data-testid="toggle-password"]` - Password visibility toggle
- `[data-testid="password-strength"]` - Password strength indicator
- `[role="alert"]` - Error/success messages
- `a:has-text("Forgot password")` - Forgot password link
- `a:has-text("Sign up")` - Sign up link
- `button:has-text("Google")` - OAuth buttons
- `button:has-text("GitHub")` - OAuth buttons

---

## File Organization

```
src/routes/
├── auth.login.tsx              # Login page
├── auth.register.tsx            # Registration page
└── auth.reset-password.tsx      # Password reset page
```

All pages use:

- TanStack Router for routing: `createFileRoute()`
- React hooks for state management
- Tailwind CSS for styling
- Lucide React for icons
- Custom validation logic
- LocalStorage for demo persistence

---

## Running Tests

To run the E2E tests:

```bash
# All auth tests
bun run test:e2e -- e2e/auth-advanced.spec.ts

# With UI
bun run test:e2e:ui -- e2e/auth-advanced.spec.ts

# Headed mode (see browser)
bun run test:e2e:headed -- e2e/auth-advanced.spec.ts

# Debug mode
bun run test:e2e:debug -- e2e/auth-advanced.spec.ts
```

---

## Demo Credentials

For testing login functionality:

- **Email:** `test@example.com`
- **Password:** `password123`

For testing duplicate email detection:

- **Email:** `existing@example.com`

---

## Future Enhancements

1. Integration with actual backend API endpoints
2. OAuth provider integration (Google, GitHub)
3. Email verification workflow
4. Multi-factor authentication
5. Social login integration
6. Advanced password requirements
7. Session management
8. Token refresh mechanism
9. Rate limiting implementation
10. CSRF token integration

## Notes

- Pages are fully functional but use local demo data
- Auth tokens are simulated with localStorage
- No actual API calls are made (demo only)
- Pages are ready to be integrated with real backend
- All TypeScript types are properly defined
- Component imports use proper absolute paths
- Pages follow project design patterns and conventions
