IntelliJ 中的 Karma：测试框架意外退出

Question

已搜索此错误但没有任何有用信息，因此在此发布。

我对我的 Angular 应用程序进行了单元测试，当我运行它或调试它时，它成功完成。当我运行代码覆盖时，我得到

此外，我在测试中得到了这个运行 window:

"C:\Program Files\nodejs\node.exe" C:\Users\thehl\.IntelliJIdea2019.2\config\plugins\js-karma\js_reporter\karma-intellij\lib\intellijRunner.js --serverPort=9876 --protocol=http: --urlRoot=/ "--testName=^COMPONENT/CLIENT -> DynamicInputComponent "
C:\Users\thehl\.IntelliJIdea2019.2\config\plugins\js-karma\js_reporter\karma-intellij\lib\intellijRunner.js:60
      throw e;
      ^

Error: read ECONNRESET
    at TCP.onStreamRead (internal/stream_base_commons.js:111:27)

我尝试了完全重启并将所有说 karma 的东西升级到当前版本。

不知道从哪里开始调试这个。

Answer 1

问题是由最近使用 karma-parallel 进行的更改引起的。我们将单元测试分解为运行在 4 个单独的线程中，使用 4 个单独的 Web 浏览器。

我从 package.json 和 karma.conf.js 中提取了 karma-parallel 的所有参考和定义。单元测试现在在 IntelliJ 中工作正常。

从现在开始，每次我想执行此操作时，我都必须将其回滚。
