Angular 5 测试 : Expected to be running in 'ProxyZone' , 但未找到

Question

我使用 Angular cli 创建了一个新的 Angular 5 项目。当我运行默认测试时，出现以下错误:

Error: Expected to be running in 'ProxyZone', but it was not found.
at Function.webpackJsonp.../../../../zone.js/dist/proxy.js.ProxyZoneSpec.assertPresent (http://localhost:9876/_karma_webpack_/webpack:/home/sukumar/workspace/bizAnalyst/partnerportal/node_modules/zone.js/dist/proxy.js:38:1)

如何解决这个问题？

附言:Angular 版本:5.2.1

不小心把fakeAsync写错了一行，遇到了这个错误信息:

错误:

describe('My Test', fakeAsync(() => {
  it('should work', () => {

右:

describe('My Test', () => {
  it('should work', fakeAsync(() => {
