Flutter Testing Standards

Priority: P0 (CRITICAL)

Core Rules

Test Pyramid: Unit > Widget > Integration.
Naming:
```
should <behavior> when <condition>
```
.
AAA: Arrange, Act, Assert in all tests.
Shared Mocks:
```
test/shared/
```
only — no local mocks.
File Placement:
```
_integration_test.dart
```
ONLY in
```
integration_test/
```
.
Robot-First: ALL UI assertions/interactions via Robot pattern (e.g.,
```
CheckoutRobot
```
) — never raw
```
find.*
```
/
```
expect()
```
in test body.

Widget Testing & Mocking

Setup: Use

TestWrapper.init()

setUpAll

and

tester.pumpLocalizedWidget(...)

Mocking: Use GetIt registration of Mock BLoCs in
```
setUpAll
```
if created internally. Use blocTest for BLoC logic and whenListen for state transitions.
Stubbing: Always stub bloc.state and bloc.stream in
```
setUp
```
. Prohibit
```
any()
```
/
```
anyNamed()
```
.
Async: Use settle: false for loading or stream states to verify mid-process transitions.

Robot Pattern

All interactions and assertions belong in
```
*Robot
```
(e.g.,
```
expectFirstOrderVisible()
```
).
Symmetric: every
```
expectXxxVisible()
```
needs expectXxxNotVisible() pairs.
Widget tests: include a
```
pumpScreen(bloc:, settle:)
```
helper.
Widget Keys: Use WidgetKeys constants from
```
lib/core/keys/
```
— never inline
```
Key('string')
```
.

Integration Testing

Use patrolTest with IntegrationAuthHelper.loginOrSkip($) for authenticated flows.
Use $.native.tap() or
```
$.native.*
```
for native interactions (e.g., system dialogs).
Create a robot:
```
final robot = OrdersRobot($.tester)
```
— share the same class as widget tests.
Only
```
$.native.*
```
and navigation helpers may remain inline in the test body.

Anti-Patterns

No inline Key: Use
```
WidgetKeys
```
constant. No
any()
: Use typed matchers.
No local mocks: Use
```
test/shared/
```
. No missing bloc stub: Stub
```
state
```
+
```
stream
```
.
No test-body logic: Move
```
find.*
```
/
```
expect()
```
to robot. No raw find in integration tests.
No
_integration_test.dart
in
test/
: Rename or merge.
No unused imports: Remove
```
v_dls
```
when robots handle assertions. Check Material import needs.
No happy-path-only: Add
```
Edge cases
```
group. No one-sided assertions: Add
```
expectNotVisible
```
pairs.
No unchecked text casing: Verify
```
.toUpperCase()
```
,
```
.tr()
```
in source.
