单元测试 – 颤振单元测试失败

2023年9月12日 242次阅读

我试图在Flutter进行单元测试.

在pubspec.yaml中包含依赖项：

测试：任何

运行颤振分析显示没有警告.

在我的项目中的test文件夹下创建了一个unit_test.dart：

import 'package:test/test.dart';

void main()
{
    test('this is a test', (){
        expect(42, equals(42));
        //expect(42,42);
    });
}

运行颤振测试显示以下错误：

任何提示？

最佳答案 您必须使用以下依赖项来使用flutter测试：

dev_dependencies:
  flutter_test:
    sdk: flutter
