Testing

Lumio uses Jest for the backend and Vitest for the frontend. CI runs the backend unit and e2e suites against PostgreSQL 16 and Redis 7 service containers.

Backend tests (Jest)​

cd backend
npm test               # unit tests: @tests/**/*.spec.ts
npm run test:e2e       # e2e tests: @tests/e2e/**/*.e2e-spec.ts (needs PostgreSQL and Redis)
npm run test:cov       # unit tests with coverage
npm run test:ci        # unit (in band) + e2e, as in CI
npm run test:golden    # parser golden tests
npm run test:parsing   # parsing regression spec

Tests live under backend/@tests: unit, integration, e2e, fixtures, and helpers.

Frontend tests (Vitest)​

cd frontend
npm test

Run them from frontend/. Tests sit next to the code as *.test.ts / *.test.tsx. CI does not run them.

Coverage​

The backend unit config enforces a global floor of 8% statements, 5% branches, 8% functions, and 8% lines; the frontend has no threshold. Cover the code you change.
