Every layer of the invite chain had unit coverage and the chain was broken anyway: the proxy test proved the edge admits the landing, the page test proved it redirects onto the registration form, and neither could see that the redirect arrives in an RSC flight payload after the shell has already flushed. The operator's path — mint an invitation, open the URL in a private window, reach a usable form — was exercised by no spec at any level. The new spec mints a real invitation in the admin UI and opens it twice: once in a genuinely cookie-less context, asserting both where the visitor lands and that they never passed through the sign-in page, and once in the admin's own window, asserting the explaining panel and that the admin's session survives. A third case pins the server half through the wire. Against `origin/main` all three fail — the anonymous visitor lands on `/auth/login`, the panel does not exist, and the registration POST answers 201 over a live session. The minted URL gains a test id so the spec reads it from its own element rather than from the first paragraph in the ticket.
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.
