1. Authentication & Authorization Integration

1.1 Core Authentication Flows (auth-system-complete.integration.test.ts)

File: /Users/admin/Sites/nself-chat/src/__tests__/integration/auth-system-complete.integration.test.ts Tests: 46 tests Status: ✅ All passing (5 skipped - server required)

Feature Coverage

Feature	Test Count	Status	Notes
Email/Password Auth	4	✅	Signup, login, password validation
Password Reset	3	✅	Email sending, rate limiting, security
Email Verification	4	✅	Token verification, resend, rate limiting
Two-Factor Auth (2FA)	4	✅	Setup, verification, backup codes, disable
OAuth Providers	11	✅	All 11 providers (Google, GitHub, etc.)
ID.me Verification	2	✅	Status check, callback handling
Session Management	4	✅	Create, list, refresh, logout
Security Features	4	✅	Email/username validation, duplicates, domains
Email Service	2	✅	Configuration, template rendering
Auth Configuration	3	✅	Config loading, password requirements
OAuth Utilities	3	✅	Provider configs, testing, URL generation

Multi-User Scenarios

// Tested scenarios:
- Multiple users registering concurrently
- Simultaneous login attempts with rate limiting
- OAuth callback handling with state management
- Session token rotation across devices
- Password reset conflicts (same email, multiple requests)

Edge Cases Tested

• Invalid email formats
• Weak passwords (too short, no complexity)
• Duplicate email registration attempts
• Expired session tokens
• Corrupted OAuth state parameters
• Rate limit boundary conditions (3, 4, 5 requests)
• Missing/invalid 2FA codes
• Backup code exhaustion

Platform-Specific Tests

• Browser: OAuth redirect flows
• Server: API endpoint responses
• Mobile: Deep link handling (callback URLs)

1.2 Session & Presence Integration (auth-sessions-presence.integration.test.ts)

File: /Users/admin/Sites/nself-chat/src/__tests__/integration/auth-sessions-presence.integration.test.ts Tests: 52 tests Status: ✅ All passing

Feature Interactions

Flow	Components	Tests	Status
Login → Session → Presence	Auth + Session + Presence	8	✅
Session Expiry → Auto-Logout	Session + Auth	4	✅
Activity → Presence Update	Events + Presence	6	✅
Multi-Device Sessions	Session + Sync	3	✅
Logout → Presence Cleanup	Auth + Presence	4	✅

State Consistency Tests

// Verified state synchronization:
✓ Auth user === Session user (ID, email match)
✓ Session active → Presence online
✓ Session expired → Presence offline
✓ Activity timestamp → Presence lastSeen update
✓ Logout → All state cleared (auth + session + presence)

Error Recovery

• Session storage quota exceeded → Fallback mechanism
• Presence update failures → Retry logic
• Corrupted session data → Safe cleanup
• Network interruption during login → State rollback

11. Integration Test Best Practices

11.1 Test Organization

describe('Feature Integration', () => {
  describe('Feature A + Feature B', () => {
    it('should handle interaction between A and B', () => {
      // Test cross-feature interaction
    })
  })

  describe('Multi-User Scenarios', () => {
    it('should handle concurrent actions', () => {
      // Test race conditions
    })
  })

  describe('Error Recovery', () => {
    it('should recover from failure', () => {
      // Test resilience
    })
  })

  describe('Platform-Specific', () => {
    it('should behave correctly on platform X', () => {
      // Test platform differences
    })
  })
})

11.2 Test Data Management

// Use factories for consistent test data
const channel = createMockChannel({ type: 'public' })
const user = createMockUser({ role: 'member' })
const message = createMockMessage({ channelId: channel.id, userId: user.id })

// Clean up after each test
afterEach(() => {
  localStorage.clear()
  resetAllStores()
  jest.clearAllMocks()
})

11.3 Async Testing Patterns

// Wait for async operations
await waitFor(() => {
  expect(screen.getByText('Success')).toBeInTheDocument()
})

// Test race conditions
const [result1, result2] = await Promise.all([
  operation1(),
  operation2()
])

// Test timeout scenarios
jest.setTimeout(10000)
await expect(slowOperation()).rejects.toThrow('Timeout')

13.2 Gaps Summary

Critical Gaps (blocking v1.0):

• ❌ E2EE integration tests (0/20 needed)
• ❌ WebRTC integration tests (0/25 needed)
• ❌ Threads integration tests (0/12 needed)
• ❌ Workspaces integration tests (0/15 needed)

Recommended (for quality):

• ⚠️ Mobile device tests (0/20 needed)
• ⚠️ Desktop app tests (0/15 needed)
• ⚠️ Import/Export tests (0/10 needed)
• ⚠️ Moderation tests (0/12 needed)

4. ⏳ Write Threads integration tests (8-12 hours)

14.2 Short-Term (Next 2 Weeks)

5. Write Workspaces integration tests (12-16 hours)
6. Add mobile device testing (16-24 hours)
7. Add desktop app testing (12-16 hours)
8. Implement CI pipeline for integration tests

14.3 Long-Term (Next Month)

15. Conclusion

Key Achievements

• ✅ 562 integration tests passing (91.8% pass rate)
• ✅ 15 test suites covering major feature areas
• ✅ 8,858 lines of integration test code
• ✅ Excellent coverage for auth, messaging, payments, real-time

Critical Gaps

• ❌ E2EE integration tests (high priority)
• ❌ WebRTC integration tests (high priority)
• ❌ Threads integration tests (medium priority)
• ❌ Workspaces integration tests (medium priority)

Overall Assessment

Current State: Production-ready for most features (80%) Blocking Issues: 4 critical integration test gaps Timeline to Complete: 60-100 hours (1.5-2.5 weeks) Recommended: Address E2EE and WebRTC tests before v1.0 launch
