我一直在审查这里提出的所有类似问题，但是似乎没有答案可以解决我的问题。 我正在使用Karma，Jasmine和Webpack测试Angular 7应用程序。当前，测试正在执行并通过（我仅测试组件和服务已创建）。但是，当Karma完成并关闭进程（Ctrl + C或使用singleRun = true自动关闭）时，会出现以下错误：
Cannot read property 'success' of undefined
TypeError: Cannot read property 'success' of undefined

如果需要，我将编辑更多文件。感谢您的帮助！
编辑：事实证明我使用了错误的配置文件，并尝试使用angular-cli，尽管我确实不需要它。
