Question

我已经将Angular 4应用程序迁移到了Angular 6，现在测试用例在终端中出现以下错误消息失败，并且在浏览器上显示成功。另外，有时测试用例通过而未显示任何错误消息。因此，可以说我在执行ng test时有60％的时间出现错误。

Chrome 67.0.3396 (Linux 0.0.0) ERROR
 {
    "message": {
      "isTrusted": true
    },
    "str": "[object ErrorEvent]"
  }

我曾尝试升级和降级茉莉花和茉莉花芯

这是我的package.json

我通过将以下导入添加到test.ts文件中解决了这个问题：

<hr class="star-light">

不知道确切原因。但这对我有用。

注意：我使用的是摩卡咖啡，而不是茉莉花，因此我想您需要将import 'zone.js/dist/long-stack-trace-zone'; import 'zone.js/dist/proxy.js'; import 'zone.js/dist/sync-test'; import 'zone.js/dist/mocha-patch'; import 'zone.js/dist/async-test'; import 'zone.js/dist/fake-async-test';更改为'zone.js/dist/mocha-patch'

Angular6测试用例因不相关的错误消息而失败
