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
