// Playwright E2E / visual-regression / a11y harness for BillTracker.
|
|
// See docs/QA_PLAN.md §4.4 and the B-UI / B14 / B15 batches.
|
|
//
|
|
// Setup (one-time): npm install && npx playwright install chromium
|
|
// Run: npm run test:e2e (headless)
|
|
// npm run test:e2e:ui (watch/debug)
|
|
// npm run test:e2e:update (re-baseline screenshots)
|
|
//
|
|
// SAFETY: the two `webServer` entries boot the app against a SCRATCH DB
|
|
// (e2e/setup/prepare-db.js seeds it) on DEDICATED ports (5199 UI / 3099 API), so
|
|
// E2E never touches your real db/bills.db and never reuses a dev server running
|
|
// on 5173/3000. `reuseExistingServer` is false for the same reason.
