Beside All, 12 months and 3 months the timeline takes a range of the person's own choosing, from and to, through the app's date field. Each change is clamped softly: never past today, never before the record's first entry, never inverted, never longer than fifteen years. On a phone, where the chronicle has no zoom control, a range button opens the same fields with a way back to the whole record. A range with nothing in it keeps its fields instead of the empty-record notice. The zoom and the range live in the URL (zoom, from, to), so Back and a bookmark return to them; a parameter that does not read falls back to All. The API accepts zoom=range with both ends, at most fifteen years, and picks the bucket by its length: quarters from two years, months from 120 days, weeks from 42 days and single days below, a new day bucket whose dashed bridge spans at most three missing days. A range borrows the grid and the keyboard steps of the fixed zoom nearest its length. The selection bar heads a day bucket with that day.
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.
