Karma Server，启动但不运行任何测试，并在控制台中显示上述错误。有人可以帮我弄清楚为什么会发生这种情况吗？

这是我的依赖项：

我也遇到了同样的问题。我刚刚解码了错误消息中的 Base64，它似乎是测试设置代码：

  import { getTestBed } from '@angular/core/testing';
  import {
    BrowserDynamicTestingModule,
    platformBrowserDynamicTesting,
   } from '@angular/platform-browser-dynamic/testing';

  // Initialize the Angular testing environment.
  getTestBed().initTestEnvironment(BrowserDynamicTestingModule, platformBrowserDynamicTesting(), {
    errorOnUnknownElements: true,
    errorOnUnknownProperties: true
  });

当然。我还没有更接近解决问题，但我希望这可以帮助别人理解它。
