Testing

Every acceptance criterion of a story has an automated test named after the story: us-inv-05.spec.ts or describe("US-INV-05", …).

Kind	Where	Runs with
Unit	next to the code, *.test.ts(x)	Vitest (API, web, shared, @spine/ui), Jest (field app, @spine/ui-native)
Integration	apps/api/src/**/*.integration.test.ts	Vitest against Postgres; each test file gets its own copy of the database
End-to-end	apps/e2e/tests	Playwright against a real API and web app, with axe-core on every route in light and dark mode
Accessibility	*.a11y.test.tsx beside each component	axe in jsdom; every component and route meets WCAG 2.1 AA

Before a pull request

1. pnpm lint, pnpm typecheck and pnpm test, plus the API’s integration tests if you changed the API.
2. pnpm verify runs everything, E2E included. CI doesn’t run E2E on pull requests (only before a release), so say in the pull request which commit pnpm verify passed on.

The definition of done, and the QA script testers follow before a release, are in 11-testing-release and qa-script.
