The journey's isolation went one way only. `test.describe.configure` orders the tests inside the file; the suite is fullyParallel with two workers, so everything else runs beside it — and its own trigger, the admin reminder sweep, walked the whole instance and dispatched for every account that had an overdue dose. With the mail env pointed at the local responder, that would have started sending real messages for accounts this file has never heard of, and the exact-equality assertion on the accepted recipients would have been reading them. The sweep now names the account it then counts, and the comments that defended the opposite direction say what the exposure actually is. Its own server, too, and for two reasons. The `SMTP_*` vars decide whether the Email card renders at all, so on the shared server they put a card the axe scan and the card-anatomy sweep had never measured onto `/settings/integrations` for every spec that opens the route. And unset, `HEALTHLOG_PROCESS_TYPE` starts the pg-boss reminder scheduler inside the process serving requests, whose every-fifteen-minutes tick either mints the missed-dose row that makes the sweep skip its own dispatch or dispatches beside it. A third server carries both: mail configured, `web`, and only this spec talks to it. The shared server keeps `all` on measured grounds rather than taste. Worker status is per-process and in-memory, so a `web` process reports the worker stopped, `/admin` renders that row destructive-red, and axe fails it at 3.97:1 against the muted tile — a real contrast defect any operator running the documented web/worker split already sees, and not this branch's to fix. That limit is written where the server is defined. Also here: the stub draws its port per run instead of pinning one, and says so by name when the port is taken; teardown ends its sockets and survives a setup that never got as far as starting it; the ledger reset stops deleting rows whose subject is this account but whose recipient is somebody else, and clears intake events explicitly rather than through a cascade; the attempt poll refuses a window larger than the twenty rows the diagnostic returns; and the header names the precondition the file cannot enforce and the internal reasons it pins on purpose. Verified against a production build and a throwaway Postgres: the journey three times over at one worker, then the a11y and settings geometry specs at two. Both assertions broken once to see them fail.
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.fixtures/— synthetic payloads a journey uploads, built in code rather than committed as blobs so the content stays reviewable (apple-health-export.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.
