Angular 5测试:预计在'ProxyZone'中运行,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,我收到以下错误:

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)

如何纠正这个问题？

PS:Angular版本:5.2.1
