A medication arrived as up to four kinds of item (its own span, its courses, its dose changes, its pauses) and was drawn item by item, so a medication with a course read as two bars on two rows. Every item of one medication now carries the medication's id as `group`, and the lane draws one row per group: the courses are the stretches it was taken, each dose change cuts them into pieces labelled with their dose, and a pause is a gap in the same bar. The selection bar and the phone chronicle list one entry per medication with the dose in the text. The value series cap of six is gone. The response carries `availableSeries`, every series the record can show, and the picker is one compact "Values (n)" button whose menu lists them. Past the fifth line the five data colours repeat; every line is named at its left. Choosing a range opens a popover anchored to the "Range" segment (a sheet on a phone) with "Apply", so the chart no longer moves; the URL keeps the range as before. The selection bar sits on the card under a hairline instead of a grey box, the legend explains the dashed stroke and the hollow point, and no timeline text joins its parts with a middle dot or calls an open span "ongoing".
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.
