Testing

Run the smallest relevant suite while iterating, then the full quality gates for the affected surface. Unit and integration tests use Vitest or Node's test runner; browser workflows use Playwright. Database tests must use an isolated database and deterministic fixtures.

Documentation changes run npm run docs:lint; runtime evidence additionally runs npm run docs:journeys against the intended image. Application changes also require type checking, linting, and relevant product tests. Do not update a snapshot or evidence image until the underlying behavior has been inspected.

The documentation test layer supplements the existing unit, integration, and Playwright suites. A documentation journey is evidence for a documented user workflow; it is not a substitute for product correctness tests.
