Я пытаюсь запустить/настроить интеграционный тест. Я гуглю возвращенный ответ, но не могу понять, что не так.

У меня есть: integration_test папка с app_test.dart файлом внутри:

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

void main() {
  IntegrationTestWidgetsFlutterBinding.ensureInitialized();

  testWidgets("failing test example", (WidgetTester tester) async {
    expect(2   2, equals(5));
  });
}
 

test_driver папка с integration_test.dart файлом внутри:

 
Future<void> main() => integrationDriver();
 

test папка с widget_test.dart файлом внутри:

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

void main() {
  test("This is a sample UNIT test", () {
    print("This is a UNIT test");
  });

  testWidgets('This is a sample WIDGET test', (WidgetTester tester) async {
    print("This is from the WIDGET test function 1");
    await print("This is from the WIDGET test function 2");
    print("This is from the WIDGET test function 3");
  });
}
 

Из-за вкусов, которые у меня есть, это то, что я использую для запуска своего интеграционного теста:

flutter drive --driver=test_driver/integration_test.dart --target=integration_test/app_test.dart --flavor prod -t lib/main_prod.dart

Я получаю следующий ответ:

From what I understand it’s trying to connect to a local port but I can’t figure out why as web is not enabled for this project.

UPDATE

This is the error, but it’s not descriptive enough to tell me where in the code this is happening.

Из того, что я видел, это такая строка: Расширение requestData не зарегистрировано

Это связано с тем, что драйверы интеграции не настроены или, возможно, не работают из-за асинхронности. Я осмотрелся и пока не нашел никакого решения.
