The glucose display unit had thirty-odd readers and, until recently, no control to set it. Nothing in the browser suite walks the path a person actually takes: capture a reading in mg/dL, switch the account to mmol/L, capture a second one, and read both back — each converted, none of them reinterpreted — in the list and on the dashboard strip. The journey covers that end to end, plus the boundary: a value past the plausible ceiling is refused by the server, the capture keeps what was typed, and the list is exactly what it was. One reading arrives with no meal-time context, the way a meter export or a device sync delivers one. It reads back correctly in the list; the tile it should paint does not exist yet (#943), so the tile assertion is skipped by issue number rather than softened into something that passes. Three supporting changes: - The list rows carry what they hold — type and resolved display unit on the row, a slot on the value cell — so the journey pins "this reading now reads in mmol/L" structurally instead of matching translated copy that also paints through a different subtree on the card list. The meal-time options carry their enum for the same reason. - The sharing-marker weight rows were seeded by handing a Date to a `timestamp without time zone` column, which stamps them in the host's zone. On a machine east of UTC that put them hours in the future, where every fold whose window ends "now" skips them, and the type stayed uncovered — which keeps the snapshot's thick phase cold and the whole tile strip short. Seed the instant as UTC, the shape the app's own writes use. - The file mutates one shared account and reads global verdicts off it, so it runs in a single project alongside the visits and immunization journeys.
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.
