Summary by CodeRabbit

  • Tests
    • Improved end-to-end test reliability by isolating test accounts, sessions, and shared test data.
    • Enabled parallel test execution to shorten validation times.
    • Added safeguards for maintenance-mode scenarios that require sequential execution.
    • Added automatic test-data preparation before test runs.
    • Reduced test interference and failures caused by shared authentication state or duplicate accounts.

Review Change Stack

Walkthrough

Playwright E2E tests now run in parallel, except for maintenance-mode tests. Supabase sign-ins use isolated clients. Test users and emails are unique per test. Shared seed data is created during global setup.

Changes

E2E reliability and parallel execution

Layer / File(s) Summary
Parallel test orchestration
.github/workflows/frontend-tests.yml, apps/frontend/package.json, apps/frontend/playwright.config.ts, apps/admin-panel/playwright.config.ts
CI runs parallel and @no-parallel suites separately. Playwright uses multiple workers and fully parallel execution.
Session and fixture isolation
apps/frontend/tests/supabase.ts, apps/admin-panel/tests/supabase.ts, apps/frontend/tests/fixtures/*, apps/admin-panel/tests/fixtures/*, apps/frontend/tests/e2e/auth.spec.ts, apps/frontend/tests/e2e/chat.spec.ts
Sign-in flows create non-persistent clients. Test accounts use unique identifiers. User cleanup uses paginated email lookup.
Shared seed lifecycle and fixture data
apps/frontend/tests/global-setup.ts, apps/frontend/tests/fixtures/test-with-documents.ts, apps/frontend/tests/fixtures/test-with-chat-search.ts, apps/frontend/tests/fixtures/test-desktop-only-with-many-chats.ts
Global setup creates or reuses the seed user and shared documents. Chat fixtures insert records with the admin client. Document cleanup preserves shared seed documents.
Maintenance test isolation
apps/frontend/tests/e2e/maintenance-mode.spec.ts
Maintenance-mode tests are tagged @no-parallel and use the authenticated user's JWT for the update request.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🔵 Low · up to 91996

The change improves parallel E2E execution but can occasionally reuse the wrong shared document, leave partial or duplicate seed data, fail when Auth data spans multiple pages, or retain test users after cleanup; it is mergeable with explicit owner awareness and follow-up on test-state isolation and mutation retries.

Poem

A rabbit checks each worker’s queue
Fresh sessions hop through tests anew
Seed docs wait in folders bright
Maintenance runs alone at night
Parallel paws make suites take flight

In `@apps/backend/src/retrying-fetch.ts`:
- Around line 66-76: Update the catch block in the retrying-fetch flow to detect
and immediately rethrow an AbortError before assigning lastError or calling
wait. Preserve the existing retry behavior for other network errors, using the
error handling around fetch and the existing abort-error identification logic if
available.
- Around line 46-48: Update the retry loop in retryingFetch to retry only
idempotent GET and HEAD requests; return or propagate failures for POST, RPC,
and all other mutation methods without another fetch attempt, while preserving
the existing retry behavior for GET and HEAD.

In `@apps/frontend/tests/e2e/auth.spec.ts`:
- Around line 292-303: Update the registration test cleanup around
givenUserEmail so it does not rely on the first page returned by
auth.admin.listUsers(); either paginate through all users until the email is
found or retain the created user ID and call deleteUser with that ID, while
preserving cleanup for the test-created account.

In `@apps/frontend/tests/global-setup.ts`:
- Around line 36-42: Update ensureSeedUser to paginate auth.admin.listUsers
beyond the first page, checking each returned page for SEED_USER_EMAIL and
stopping once found or no further users remain; preserve the existing listError
handling and avoid calling createUser when the seed user exists.

- Line 68: Update the seed-document lookup around the query filtering

include that ID in the document filter so only the "Alle" document can satisfy
