The batched compliance read allows thirty calls a minute per ACTOR, and the journey spends that allowance twice over: it writes doses and then reads the resulting rates back off the same cabinet. On the shared account two siblings spend it as well — `refetch-nav.spec.ts` mounts `/medications` unstubbed and drives a client-side round trip back to it, and `delegated-writes.spec.ts` opens `/medications?new=1` on a SECOND session row of the same account, which is a different session but the same actor and therefore the same bucket. Add a serial group's retries and thirty reads inside one minute is reachable rather than theoretical. The cabinet has the same shape of problem in the other direction: the clear before each test deletes every medication row of the account it runs on, and that is today the account every other authenticated spec holds. So the journey gets its own account and its own jar. The rate-limit bucket, the medication cabinet and the dashboard tile's denominator become private at once. Two fixture repairs ride along, because they are the same helper: - The clear now goes out as the app's own DELETE per row instead of one raw `DELETE FROM medications`. Three fifteen-minute per-user cells hold medication state and a raw statement evicts none of them; the file survived only because every test happened to write through the API afterwards, which is an accident of ordering rather than a property. The rows are still enumerated in SQL, because the list route serves a memoised shape and a row it has not caught up with would hide from it. - `ageMedication` takes both stamps from its caller instead of deriving them from `CURRENT_DATE`. That resolves in the database session's zone — UTC in CI — while the plan dates the spec sends are computed in the browser's pinned Europe/Berlin, so between midnight and 02:00 the row silently started a day earlier than the caller asked for. The docstring now says `starts_on` is overwritten, not adjusted.
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.
