NutsNews Web Offline E2E Regression Test

Section titled “NutsNews Web Offline E2E Regression Test”

This test runs the real Next.js web app against mocked Supabase/PostgREST, Turnstile, and Resend services.

It can be run from either the repository root or the web/ directory. The test starts Next.js with an absolute web working directory so npm run test:e2e:offline works reliably in local terminals and GitHub Actions.

The test verifies:

  • Home page renders with mock article cards.
  • Footer Home scrolls the page back to the top with animated movement.
  • Footer navigation works for Home, Search, Apps, About, Contact, and Privacy.
  • Search for dogs returns a mock article.
  • Settings opens and every theme can be applied.
  • Apps, About, Contact, and Privacy pages render.
  • Contact form submits through mocked Turnstile and mocked Resend.
  • A mock quota_usage_events email event is recorded.
  • Language switching renders translated article text for French, Japanese, Swiss German, German, Greek, and back to English.
  • A Supabase outage makes /api/articles use the edge snapshot fallback with lang=fr, preserving localized title, summary, language_code, requested_language_code, and translation_available=true.
  • A separate English-only fixture verifies the documented missing-translation fallback: the requested language remains fr, the card language is en, and translation_available=false.

Run:

Terminal window
cd /Users/ramideltoro/WebstormProjects/nutsnews3/web
npm install
npx playwright install --with-deps chromium
npm run test:e2e:offline

A passing run ends with:

✅ NutsNews fully offline Web E2E regression passed.
✓ Cleanup complete; exiting Web E2E regression.

Locator and mock-image stability

Section titled “Locator and mock-image stability”

The test uses strict Playwright selectors and stable data-testid hooks for the feed, footer controls, search dialog, settings menu, theme options, and language options. Those hooks exist only to keep the regression reliable across copy changes and translated UI labels.

Mock article images are served from the local mock external service so the test remains fully offline and Next Image does not try to resolve external DNS.

Issue #279 translation fallback coverage

Section titled “Issue #279 translation fallback coverage”

The outage path is now translation-aware. The mock Worker snapshot endpoint reads the lang query parameter and returns localized article rows when a matching article_summaries fixture exists.

  • Simple: if the database is down, a French reader still gets French edge snapshot cards when those translations exist.
  • Intermediate: the regression verifies both the happy path and an explicit missing-translation fallback, so English is accepted only for the English-only fixture.
  • Expert: scripts/web_offline_e2e_regression.mjs checks the response headers, languageCode, article title/summary, language_code, requested_language_code, and translation_available values for both localized fallback and missing-translation fallback.

Stability notes

Section titled “Stability notes”

The browser test scopes ambiguous controls, such as the search submit button, to their owning dialog so Playwright strict mode cannot match footer/open/close buttons by accident. The browser test also intercepts /_next/image requests and returns a tiny mock PNG so the test remains fully offline even when mock article images point at localhost.

Locator stability notes

Section titled “Locator stability notes”

The browser checks scope page-content assertions to main where possible. This avoids Playwright strict-mode conflicts with Next.js route-announcer text such as About NutsNews | NutsNews, which is useful for accessibility but is not the visible page content being tested.
