flutter - 无法从 Flutter 集成测试响应中找出问题所在

问题描述

我正在尝试运行/设置集成测试。我正在谷歌搜索返回的响应，但我不知道出了什么问题。

我有：一个integration_test包含文件的文件夹app_test.dart：

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));
  });
}

包含test_driver文件的文件夹integration_test.dart：


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

包含test文件的文件夹widget_test.dart：

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");
  });
}

由于我的口味，这是我用来运行我的集成测试的：

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

我得到以下回复：

据我了解，它正在尝试连接到本地端口，但我无法弄清楚为什么该项目没有启用网络。

更新

这是错误，但它的描述性不足以告诉我代码中发生这种情况的位置。

在此处输入图像描述

从我所见，这是这一行： 没有注册请求数据扩展

它与未设置集成驱动程序或由于异步而可能无法工作有关。我环顾四周，我还没有遇到任何解决方案。
