Robot #
This library is designed to facilitate the use of the Robot pattern when developing apps using the Flutter framework. The Robot pattern is a software testing technique that aims to encapsulate a repetitive series of user actions into classes that can be re-used efficiently to simulate & test user interaction with the app, allowing the development of higher-quality applications.
Features #

Provides the Robot class that can be extended to create a Robot for each widget in the app.

Getting started #
1. Add this to your package's pubspec.yaml file #
dev_dependencies:
robot: ^0.1.3
copied to clipboard
2. Install it by running the following command at the root of your project #
flutter pub get
copied to clipboard
3. Import it by adding the following import statement to your Flutter test code #
import 'package:robot/robot.dart';
copied to clipboard
Usage #
Create a Robot class for each widget in the app that you want to test. The Robot class should extend the Robot class from the Robot package.
class MyWidgetRobot extends Robot<MyWidget> {
MyWidgetRobot(super.tester);

late String text;

Finder get textFinder => find.descendant(of: this, matching: find.text(text));

Future<void> show() => tester.pumpWidget(MaterialApp(home: MyWidget(text: text)));

void expectText() => expect(textFinder, findsOneWidget);
}

Create a test file for each widget in the app that you want to test. The test file should import the Robot class for the widget and the Flutter test package.
import 'package:flutter_test/flutter_test.dart';
import 'package:robot/robot.dart';

import 'my_widget_robot.dart';

void main() {
group('MyWidget', () {
testWidgets('should show text', (tester) async {
final robot = MyWidgetRobot(tester)..text = 'Hello, World!';
await robot.show();
robot.expectText();
});
});
}
copied to clipboard
It can be useful to use the Robot class directly.
Robot<Text> get countText => Robot.byKey(tester, const Key('count'));
copied to clipboard
That can be used like this.
countText.expectText('Count: 0');
copied to clipboard
See more details on how to use this package in the robot_test.dart file.
