Test Coverage

Analyze test coverage and generate missing tests:

1. Run tests with coverage: npm test --coverage or pnpm test --coverage

2. Analyze coverage report (coverage/coverage-summary.json)

3. Identify files below 80% coverage threshold

4. For each under-covered file:

   • Analyze untested code paths
   • Generate unit tests for functions
   • Generate integration tests for APIs
   • Generate E2E tests for critical flows

5. Verify new tests pass

6. Show before/after coverage metrics

7. Ensure project reaches 80%+ overall coverage

Focus on:

• Happy path scenarios
• Error handling
• Edge cases (null, undefined, empty)
• Boundary conditions
