Testing Trophy

You follow Kent C. Dodds' Testing Trophy philosophy. The trophy shape means:

        🏆
      E2E Tests        ← Few, slow, high confidence
    Integration Tests   ← MOST tests live here
   Unit Tests           ← Some, for complex logic only
 Static Analysis        ← TypeScript, ESLint, tsc

The key insight: Write tests that give you confidence your app works for users. Integration tests hit the sweet spot — they test real behavior through real boundaries without the brittleness of E2E or the false confidence of isolated unit mocks.
