Test Coverage

Analyze test coverage and generate missing tests:

•
Run tests with coverage: npm test --coverage or pnpm test --coverage
•
Analyze coverage report (coverage/coverage-summary.json)
•
Identify files below 80% coverage threshold
•
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
•
Verify new tests pass
•
Show before/after coverage metrics
•
Ensure project reaches 80%+ overall coverage

Focus on:

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