在运行我的单元测试时,有时即使它们通过,在所有测试运行结束时,我也会收到以下错误.

在运行PhantomJS的Jenkins CI构建中:

.PhantomJS 2.1.1 (Linux 0.0.0) ERROR
  {
    "message": "An error was thrown in afterAll\nReferenceError: Can't find variable: $ thrown",
    "str": "An error was thrown in afterAll\nReferenceError: Can't find variable: $ thrown"
  }

或者在Chrome上:

Chrome 67.0.3396 (Windows 7 0.0.0) ERROR
  {
    "message": "An error was thrown in afterAll\n[object ErrorEvent] thrown",
    "str": "An error was thrown in afterAll\n[object ErrorEvent] thrown"
  }

我也有非常不可靠的测试,有时候他们没有改变任何东西会成功,有时候同样的测试会失败,所以我知道一些奇怪的事情正在发生.
