e2e-test

name: e2e-test description: | Run and debug Flutter E2E integration tests that exercise the real app against a local Docker backend (no mocks). Use when running E2E tests, debugging failures, or working on the local harness. author: Claude Code version: 1.1.0

E2E Integration Testing

Goal: run the real app against a real local backend, end-to-end. OAuth, relay subscriptions, and media uploads all hit local Docker services — no mocks anywhere. Tests live in mobile/integration_test/, backend in local_stack/.

Run a test

Two terminals, from mobile/:

# Terminal 1 — emulator
mise run emulator

# Terminal 2 — tests
mise run e2e_test                                              # All auth tests
mise run e2e_test integration_test/auth/auth_journey_test.dart # Single test

e2e_test brings up the Docker stack, runs patrol, captures a merged docker+logcat+app timeline at test_reports/*.jsonl, and prints the native test XML path + failure excerpts when the APK fails to install. Never call patrol test directly — you'll lose the timeline and the diagnostics.

Stack

mise run local_up         # Start (auto-runs local_setup on fresh worktrees)
mise run local_up_cached  # Same, but reuse cached images (offline / rate-limited)
mise run local_down       # Stop
mise run local_reset      # Wipe data + restart
mise run local_status     # Health

If local_up fails only at e2e-seed and the services your test actually needs are healthy (auth tests don't need the indexer), bypass the seed:

bash ../local_stack/profile.sh integration_test/<your_test>.dart

Emulator

mise run emulator           # Normal launch (auto-detects DISPLAY)
mise run emulator_headless  # Offscreen, no window
mise run emulator_wipe      # -wipe-data (storage exhausted)

Override AVD: AVD_NAME=<name> mise run emulator. Always uses -gpu host — swiftshader can't render media_kit frames.

Skip the per-run reinstall with PATROL_NO_UNINSTALL=true mise run e2e_test ... when iterating fast and the APK hasn't changed. Stale-state debugging cost is yours.

Buffer auth-flow logs: adb logcat -G 16M (default 256 KB rotates mid-flow).

Patterns

Launching the app

pumpAndSettle hangs because of persistent polling timers. Use launchAppGuarded (from test_setup.dart) with error suppression and a manual pump loop:

final originalOnError = suppressSetStateErrors();
final originalErrorBuilder = saveErrorWidgetBuilder();
launchAppGuarded(app.main);

for (var i = 0; i < 60; i++) {
  await tester.pump(const Duration(milliseconds: 250));
  if (find.text('Welcome').evaluate().isNotEmpty) break;
}

restoreErrorWidgetBuilder(originalErrorBuilder);
restoreErrorHandler(originalOnError);
drainAsyncErrors(tester);

Async publish → relay query

UI navigates before publish/upload completes. Poll the relay:

for (var i = 0; i < 120; i++) {
  await tester.pump(const Duration(milliseconds: 500));
  events = await queryRelay(filter);
  if (events.isNotEmpty) break;
}

Onboarding sheets blocking UI

New bottom sheets may cover the target widget:

for (var i = 0; i < 20; i++) {
  await tester.pump(const Duration(milliseconds: 250));
  final gotIt = find.text('Got it!');
  if (gotIt.evaluate().isNotEmpty) {
    await tester.tap(gotIt);
    break;
  }
}

Patrol false positives

Patrol bundles every file in a target dir into one APK. When file B runs, file A shows up as "not requested" [E] markers in logcat. Trust only the final ✅/❌ lines.

Provider error caching

Providers using requireIdentity (or similar non-nullable getters) crash during cold start and Riverpod caches the error forever. Use the nullable accessor (currentIdentity) and handle null.

Material ancestor

TextField in an overlay/transition without Scaffold needs:

Material(color: Colors.transparent, child: TextField(...))

Helpers

integration_test/helpers/:

• test_setup.dart — launchAppGuarded, error suppression, async-error drain
• navigation_helpers.dart — register, login, tap tabs, wait for widgets
• relay_helpers.dart — publish/query Nostr events
• db_helpers.dart — Postgres (verification tokens, refresh tokens)
• http_helpers.dart — Keycast API (verify email, forgot password)
• constants.dart — ports + appPackage

Debugging

# Service logs
docker compose -f local_stack/docker-compose.yml logs keycast --tail=50
docker compose -f local_stack/docker-compose.yml logs blossom | grep -v 'path=/'

# Auth trace
adb logcat -d | grep 'flutter.*\[AUTH\]' | grep -v 'Router redirect'

# Last merged timeline
ls mobile/test_reports/*.jsonl

If patrol reports Total: 0 with Gradle exit 1, the runner auto-prints the native test XML path + failure excerpts — that's an APK install failure, not a missing test. Free space with adb shell pm trim-caches 1G or mise run emulator_wipe.
