为什么Angular 8 CircleCI build在执行ng test——watch false时失败，而karma配置为singleRun=true？

我正在从迁移一个开源项目Angular@7.2.0发送至@8.2.14；它的CircleCI CI/CD管道在上运行良好Angular@7.2.0，现在在迁移到后失败Angular@8.2.14尝试执行单元测试时；测试通过，然后失败，构建尝试运行多次

我正在建立

FM-736-ng8

分支

循环的相关部分是：

karma配置文件包含一个标志，用于执行测试一次并停止，似乎没有效果。再一次，我的工作做得很好Angular@7.2.0，现在在迁移到后失败Angular@8.2.14.

• 第一次单元试运行结束：

注意测试是如何结束、通过和重新启动的。如果你看一下日志，你会发现这个过程重复了很多次，直到我杀死它

---

预期的行为是单元测试运行一次并停止

这太尴尬了！我有一个mono-repo项目，包括许多

npm包

，以及一个

应用程序

展示它们。使用

ng test

运行单元测试时，测试在运行应用程序测试后停止，而不运行包的测试

当使用

ng test--watch false运行单元测试时，应用程序测试运行，然后包测试运行；我将包错误误解为应用程序测试错误

我的错误是看我正在处理的问题，应用程序测试，而不是我最初关注的领域。很尴尬，但这是真的
