With the day panel docked beside the blood-pressure page (1280 px and up), each half of the stat card is a narrow column, and its four cells still went side by side because the step followed the window's width. Every cell came out narrower than "112 mmHg": the systolic values broke onto two lines, the two-digit diastolic ones next to them did not. The stat strip now joins a value to its unit with a no-break space, and each series is a container whose cells go four-up only when the series itself has the room: from 28rem for a half-card column, from 36rem for a full-width strip (where the 640 px window step put it, so the longest unit written, mL/(kg·min), keeps a cell it fits in). The loading shell follows the same steps. Every page with a stat strip (pulse, weight, the HealthKit, lab and custom-metric pages) shares the component. A component test pins the no-break pair and the container steps; the day-view spec measures every blood-pressure value beside the docked day at 1280 px and fails on the old markup.
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.
