flutter-testing SKILL.md skillA
flutter-testing from smicolon/ai-kit is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add smicolon/ai-kit/flutter-testing@v1.0.0Pins v1.0.0 in mdr.lock. Pin the fingerprint instead.

Guides writing unit tests, widget tests, and integration tests in Flutter using flutter_test, WidgetTester, Mockito/Mocktail, and integration_test.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

# Flutter Testing Best Practices
Comprehensive testing strategies for Flutter apps across unit, widget, and integration levels.
## 1. Widget Testing (`flutter_test`)
Use `testWidgets` to render UI components in an isolated test environment without a physical device or emulator.
```dart
import 'package:flutter_test/flutter_test.dart';
import 'package:flutter/material.dart';
import 'package:myapp/ui/counter_widget.dart';
void main() {
testWidgets('Counter increments smoke test', (WidgetTester tester) async {
// 1. Pump the widget inside a MaterialApp
await tester.pumpWidget(
const MaterialApp(home: Scaffold(body: CounterWidget())),
);
// 2. Verify initial state
expect(find.text('0'), findsOneWidget);
expect(find.text('1'), findsNothing);
// 3. Perform tap interaction
await tester.tap(find.byIcon(Icons.add));
await tester.pump(); // Trigger frame redraw
// 4. Verify updated state
expect(find.text('0'), findsNothing);
expect(find.text('1'), findsOneWidget);
});
}
```
### Key Tester Methods
- `tester.pumpWidget(widget)`: Renders the given widget tree.
- `tester.pump()`: Re-renders the frame (synchronous setState).

How to install
mdr add smicolon/ai-kit/flutter-testing@sha256:b6098c873f99ef10The line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
