Question

编辑：我不确定出什么问题，但是我一直在编写测试，当我进行80次测试时，错误停止出现。

我有一个角度项目设置，可以使用Karma和Jasmine进行单元测试。我最近一直在添加测试，现在每当运行70个或更多测试时，所有测试都运行后，我会收到此消息：

ERROR: 'Unhandled Promise rejection:', '<toHaveBeenCalledWith> : Expected a spy, but got Function.
Usage: expect(<spyObj>).toHaveBeenCalledWith(...arguments)', '; Zone:', 'ProxyZone', '; Task:', 'Promise.then', '; Value:', Error{}, 'Error: <toHaveBeenCalledWith> : Expected a spy, but got Function.

我的所有测试都成功执行，并且因果报应完成，没有出现任何问题，即使出现此错误：

Chrome 67.0.3396 (Mac OS X 10.12.6): Executed 70 of 70 SUCCESS (3.541 secs / 3.246 secs)
TOTAL: 70 SUCCESS

如果我甚至注释掉一个测试（与哪个测试都没有关系），那么该错误消息将不再出现，并且我无法弄清楚发生了什么。

这是我的karma.conf.js：

在继续添加测试并达到80个测试之后，问题得以解决，不确定为什么随机的测试数量会出现问题。

因果报应一个间谍，但获得了功能
