【问题描述】：

我正在尝试在 karma 中进行测试，但每次运行 Karma 时都会遇到相同的错误：

$ karma start karma.conf.js --single-run

31 07 2018 12:56:48.134:INFO [karma]：Karma v1.7.1 服务器开始于 http://0.0.0.0:9876/

我的（大部分）自动生成的 karma.conf.js 位于测试上方一层：C:\Users\king\Desktop\_REPOS\inventivangular\src

module.exports = function(config) {
  config.set({

【解决方案1】：

刚从C:\Users\king\Desktop\_REPOS\inventivangular 运行ng test 就结束了，它生成了自己的 karma.conf.js 并且一切正常。

如果您使用自动生成的测试，您可能需要：

import { HttpClientTestingModule } from '@angular/common/http/testing'

和

imports: [HttpClientTestingModule]
