Flutter Test Driver Run All Test - testing

Question

In our Flutter application we have multiple integration tests.
I run them one by one by issuing:
flutter drive --target=test_driver/screenshot.dart
However I can't seem to figure out how to run all integration test inside the test_driver folder?

Answer 1

With Groups, but this only half addresses the issue, have your app_test.dart like normal just a main method with some grouped tests
Future<void> main() async {
group(
'Registration and password',
() {
setUp(() async {
await versionTest(driver, tester, reporter);
});
test('Register Account', () async {
await testRegisterAccount(driver, tester, reporter);
});
test('Register Account 2', () async {
await testRegisterAccount2(driver, tester, reporter);
});
tearDown(() async {
await driver.requestData('go-back');
});
},
timeout: const Timeout(
Duration(minutes: 5),
),
);
then we have an app.dart which creates the app wrapped in a test app. We mainly did this to test a splash screen that checked the apps version, so we needed a hook into before the app had really started
void main() {
makeTestApp();
}
makeTestApp does all the normal stuff like enableFlutterDriverExtensions etc but its also where we build our app with a custom launcher, the launcher is just a blank page with a button which starts the app, each test should start and finish here, going back was harder you can see we used the FlutterDriverExtensions handler message - driver.requestData('go-back')
Widget _buildHome(BuildContext context) {
return Scaffold(
child: Center(
child: GestureDetector(
onTap: () {
Navigator.of(context).pushReplacementNamed('/authentication');
},
child: SizedBox(
height: 200,
width: 200,
child: Image.asset(
'assets/images/logo.png',
fit: BoxFit.cover,
),
),
),
),
);
}
WidgetsFlutterBinding.ensureInitialized();
SystemChrome.setPreferredOrientations([DeviceOrientation.portraitUp]).then((_) {
runApp(App(
launcher: (context) => _buildHome(context),
));
});
now you can start the app using something like
flutter run --flavor dev --observatory-port 8888 --disable-service-auth-codes --no-hot test_driver/app.dart
and when the app is running it will display our launcher waiting for you to run a test using the code lens tools from the dart library,

One way to do it is to open a terminal window in the root directory of your Flutter app and type flutter test
