我试图在 Flutter 中进行单元测试。

在pubspec.yaml依赖项中包括：

test: any

运行flutter analyze不显示任何警告。

在我的项目中创建了一个unit_test.dart下文件夹：test

import 'package:test/test.dart';

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

运行flutter test显示以下错误：

➜  HelloFlutter flutter test test/unit_test.dart
00:00 +0: loading /home/tr/programs/HelloFlutter/test/unit_test.dart            00:00 +0 -1: loading /home/tr/programs/HelloFlutter/test/unit_test.dart         00:00 +0 -1: loading /home/tr/programs/HelloFlutter/test/unit_test.dart

  websocket_impl.dart 333   _WebSocketProtocolTransformer._messageFrameEnd
  websocket_impl.dart 228   _WebSocketProtocolTransformer.add

00:00 +0 -1: Some tests failed.

有什么提示吗？

The actual test you posted looks like a regular "test" test, as opposed to a "flutter_test" test. So you probably just want to run it using regular dart rather than via flutter's test harness.

The diagnostics we give in these situations are horrific. That's being tracked at: https://github.com/flutter/flutter/issues/6187

您必须使用以下依赖项才能使用flutter test：

dev_dependencies:
  flutter_test:
    sdk: flutter
