Angular 7:ng测试挂起,反复运行测试

我最近将我的Angular 6应用程序迁移到了Angular 7

我的package.json看起来像这样:

  }
}

奇怪的是,当runnung:ng test –watch = false –code-coverage

服务器无限期地继续运行并重新运行测试,无需停止并且不生成覆盖文件.

这个问题似乎很奇怪

Sugestions ??

最佳答案 我有一个类似的问题,我发现在Angular 7中他们改变了,当你在没有指定特定项目的情况下运行测试时,它会运行你在angular.json工作区文件中所有项目的测试,而不仅仅是主应用程序.然后看起来它无限期地继续或者有一个bug并且它循环项目.

尝试运行ng test< projectname>看看你是否仍然如此.对我来说,这解决了这个问题.

这里还有一个指向official documentation的链接,在命令描述中对其进行了解释.
