Several accessibility scans ran against a page that had not finished arriving, so axe reported violations the app does not have. The worst of them was the medications case, which waited for a level-one heading and then checked that a level-one heading exists. A page that really lost its heading would have waited out the timeout under a misleading name instead of failing the rule, which makes it a check that cannot fail rather than a flaky one. The filter rail was the other bad sentinel. It renders beside the loading silhouettes rather than after them, so it was on screen while the rows were still grey rectangles. Under an 8x CPU throttle the rail and the loading marker resolved in the same 40ms poll and the rows a poll later. Every case now gates on a marker the real component carries in its resolved, non-empty branch, and on a component other than the one the scan asserts. Both the desktop table and the mobile card list carry the same marker so the wait holds at any viewport. No sentinel names a heading, the app frame, a busy marker or the filter rail any more.
e2e/
End-to-end browser tests. Playwright 1.60 drives a production build of the app against a real PostgreSQL, with @axe-core/playwright for accessibility assertions. This is the heaviest test tier; CI runs it on every PR, and locally it is worth running when a change touches a UI flow.
Running
pnpm e2e
The Playwright config (../playwright.config.ts) builds the app (next build) and brings up Postgres before the specs run; setup/global-setup.ts seeds the auth + fixture state. The suite is not part of the fast local gate (typecheck / lint / test) — it surfaces at PR CI, so expect responsive/wizard/nav reworks to flag here first.
Layout
setup/—test.ts(the suite'stest+expectentry point),global-setup.ts(auth + DB seeding),test-helpers.ts(shared login + navigation helpers).utils/— fixtures such asmock-dashboard-snapshot.ts.*.spec.ts— one spec per flow: auth/login/redirect, dashboard, charts, the medication-wizard cadences (medications-wizard-*), insights generation + scroll restoration, doctor report, settings, mobile-viewport consistency, locale switch, accessibility (a11y.spec.ts), and thev1427-*regression set.
Conventions
Import test and expect from ./setup/test, never from @playwright/test — types (Page, Route, …) still come from the package. The entry point extends Playwright's test with an automatic fixture that drops route handlers and page listeners after every test, so a handler left in flight cannot fail the test it belonged to once the context closes. src/__tests__/e2e-route-cleanup-guard.test.ts enforces the import boundary.
Assert against stable data-* attributes (data-slot, data-display-step, root display attrs), not viewport-dependent visible text. Responsive sm:hidden UI changes break getByText on desktop while the underlying element is still present — anchoring on data attributes keeps the specs stable across breakpoints. See ../CLAUDE.md.
