从10.1->12.0，但是当从10.1->11.0
ng test编译并打开web浏览器，但测试无法运行。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需要是test.ts文件中的第一个导入。作为升级的一部分，import语句被更改为import 'zone.js/testing';。我试过两者的每一种组合，但没有一种能让这些测试奏效。

有人能帮忙吗？
尝试生成一个全新的Angular 12.0.3项目并运行单元测试。如果这样做有效，那么很可能存在配置问题。
转到项目的package.json，将单元测试的关键包与新生成的包进行比较(查找karma、karma-jasmine、jasmine(，并确保它们匹配。一旦它们匹配，删除package-lock.json并运行新的npm安装。
最后，对两个项目的test.ts进行了比较。希望问题能解决。
发现问题是由我的tsconfig设置引起的。不确定我是否遗漏了文档，但我不得不将模块设置更改为es2020，将目标设置更改为es2017。
感谢AliF50建议使用新项目来比较配置。经过大约8个小时的比较和测试，我找到了答案。
