Flutter + Riverpod 3 — testing

Tiers

unit (package:test, no Flutter) → widget (testWidgets, flutter_test) → integration (integration_test, device/emulator).
e2e/integration — only critical flows; everything else with unit tests (see the core skill tdd).

Riverpod

ProviderContainer.test() (v3, auto-disposes at the end). Do NOT share a container between tests.
Value: container.read(provider); for autoDispose — container.listen(...), read through the subscription.
Async: await expectLater(container.read(provider.future), completion(...)).
Widget: ProviderScope at the root of pumpWidget, container — tester.container().

Override (everything is mockable with no setup)

provider.overrideWith((ref) => fake);
notifierProvider.overrideWithBuild((ref, self) => state) — mock only build, real methods;
futureProvider.overrideWithValue(AsyncValue.data(x)).

Mocks

mocktail (no codegen) — default. Mock the repository that the Notifier uses, not the Notifier itself.
Golden: matchesGoldenFile('name.png'), update with flutter test --update-goldens. Run on a single CI image (goldens are sensitive to platform/fonts/version).

Accessibility in tests

meetsGuideline(textContrastGuideline), androidTapTargetGuideline/iOSTapTargetGuideline, labeledTapTargetGuideline — enforce contrast and tap-target size (48×48 Android / 44×44 iOS).

Said here and by no other author read

cover everything else with unit tests
create a fresh ProviderContainer for each test
mock the repository not the notifier
use mocktail as the default mocking tool
read autoDispose providers through a subscription
place ProviderScope at the widget root
