I have multiple test-classes under folder "integration-test" (e.g. "class1_test.dart", "class2_test.dart"...); I found scripts to generate app-apk and test-apk and run on Firebase TestLab, but these scripts generate test-app for particular test-class, but I would like to run all my tests at once, not only from particular class. How can I do that?

pushd android
flutter build apk 
./gradlew app:assembleAndroidTest
./gradlew app:assembleDebug -Ptarget=integration_test/class1_test.dart #generates apk for 1class 
popd

gcloud firebase test android run \
  --type instrumentation \
  --app build/app/outputs/apk/debug/app-debug.apk \
  --test build/app/outputs/apk/androidTest/debug/app-debug-androidTest.apk

Tried to specified few --Ptarget arguments for ./gradlew app:assembleDebug, but anyway it generates test-app with tests only in class1

To run multiple integration tests in the same APK, you can follow these steps:

First, create a separate test file for each test class. For example:

  • integration_test/test1.dart
  • integration_test/test2.dart

In each test file, import the necessary packages and create your test functions. For instance:

import 'package:flutter_test/flutter_test.dart';
import 'package:integration_test/integration_test.dart';

void main() {
  IntegrationTestWidgetsFlutterBinding.ensureInitialized();

  group('Test1', () {
    testWidgets('Test case 1', (WidgetTester tester) async {
      // Your test logic here
    });

    testWidgets('Test case 2', (WidgetTester tester) async {
      // Your test logic here
    });
  });
}

Create a test_driver directory, and within it, create an integration_test.dart file. This file will be responsible for running all your test files:

import 'package:integration_test/integration_test_driver.dart';
import '../integration_test/test1.dart' as test1;
import '../integration_test/test2.dart' as test2;

Future<void> main() async {
  await integrationDriver(test1.main);
  await integrationDriver(test2.main);
}

In your pubspec.yaml file, make sure you have the necessary dependencies and

dev_dependencies:

dependencies:
  integration_test:
    sdk: flutter

dev_dependencies:
  flutter_test:
    sdk: flutter
  integration_test:
    sdk: flutter

Create a test_driver folder (if you haven't already) and, within it, create an app.dart file. This file should import your app's main file and contain the enableFlutterDriverExtension() function, like this:

import 'package:flutter_driver/driver_extension.dart';
import 'package:your_app/main.dart' as app;

void main() {
  enableFlutterDriverExtension();
  app.main();
}

Make sure you have the Flutter Driver package installed by adding the following to your pubspec.yaml under dev_dependencies:

flutter_driver:
  sdk: flutter

Now you can run your integration tests with the following command:

flutter drive --driver=test_driver/integration_test.dart --target=integration_test/app.dart

This command will run all the test files you've specified in the integration_test.dart file in the test_driver directory. The output will show the results of each test case from all test classes.

It is pretty simple to execute many test classes together to execute in firebase test lab:

Ex: Lets say below two test classes

class1_test.dart

  void main() {
  group('Test1', () {
    testWidgets('Test case 1', (WidgetTester tester) async {
      // Your test logic here
    });
  });
}

class2_test.dart

     void main() {
  group('Test2', () {
    testWidgets('Test case 2', (WidgetTester tester) async {
      // Your test logic here
    });
  });
}

Now make a single test suite class in which you initialize the test binding and call main methods of above two classes

test_suite.dart file

import '../class1_test.dart' as testclass1;
import '../class2_test.dart' as testclass2;
void main() {
    final binding = IntegrationTestWidgetsFlutterBinding.ensureInitialized();
  binding.framePolicy = LiveTestWidgetsFlutterBindingFramePolicy.fullyLive;

//executing all tests
testclass1.main();
testclass2.main();

}

How to call in test app assemble to run in firebase test lab:

    ./gradlew app:assembleDebug -Ptarget=integration_test/test_suite.dart #generates apk for 1class 
popd

This way all of your test cases will run from a single test suite file, if you want to add more test classess , you can add in test suite file in similar way. I hope it works for you
