3.8.2 Testing & Versioning

• Versioning for critical endpoints to avoid breaking older mobile app versions.

• E2E testing ensures real-time interactions (chat, voice calls, copy trades) work on both web and iOS simultaneously.

Cypress or Playwright:

• Simulate user flows: login, create post, join channel, place a trade, see real-time updates.

• API Integration Testing (Supertest in Node):

• Verifies that each route (feeds, copy trading, etc.) behaves correctly, handles edge cases (invalid data, permissions).
