Frontend testing

Run checks that cover the changed workspace. The root baseline is:

yarn lint
yarn typecheck
yarn test

AFFiNE uses Vitest for unit tests and Playwright for browser and application E2E suites. Install Playwright browsers once with npx playwright install, then use the workspace commands listed in the current Testing section.

Use @affine-test/affine-local for web behavior that does not require the server. Cloud, desktop, mobile, and BlockSuite suites have additional dependencies; do not report them as validated unless the relevant environment actually ran.
