ng 测试 - Chrome 没有在 60000 毫秒内捕获，杀死

Question

删除项目中的所有 *.component.spec.ts 文件后，ng 测试停止工作。

输入 ng test 后，这些是日志：

$ ng test

尝试过的东西:

使用 Firefox 测试后，结果相同。
删除node_modules和package-lock.json后，结果一样

注意事项:

没有测试文件有错误。

版本：

Chrome版本：v90
@angular/core 版本: v11.1.1

Answer 1

输入 ng update 并用 ng update --force @angular/core 更新 @angular/core 后，测试再次开始在 Chrome 上运行。

这可能是特定@angular/core 版本 (v11.1.1) 或我的 Angular 包版本不匹配的问题。
