angular - 将 Angular 从 10.1 更新到 11.0/12.0 后，Karma/Jasmine 测试中断

问题描述

从 10.1 -> 12.0 开始，但从 10.1 -> 11.0 开始时也存在同样的问题

ng test编译并打开 Web 浏览器，但无法运行测试。每个测试都失败并出现以下错误：Error: zone-testing.js is needed for the fakeAsync() test helper but could not be found. Please make sure that your environment includes zone.js/testing.

我在其他几个来源中发现zone.js/dist/zone-testing需要成为test.ts文件中的第一个导入。作为升级的一部分，导入语句已更改为import 'zone.js/testing';. 我已经尝试了这两者的每一种组合，但没有一个能让这些测试起作用。
