Question

所以我已经准备好了我可爱的测试系统，但我遇到了在我的CI服务器中运行它的问题：由于某种原因，Ember Testing抱怨运行循环，但仅在运行时在PhantomJS

这是Karma输出：

正如您所看到的，他们显然正在使用Chrome！我想不出会有什么不同，但如果有人能指出我正确的方向，那就太棒了。

奇怪的是，这只发生在Chrome上，但是，问题很可能是在你的一个测试中，你遇到了异步问题。隔离并找到导致此问题的测试，然后查看它所涉及的代码部分。然后，你需要确保在该代码中（包括触发的观察者）set，create，destroy和ajax调用都包含在ember运行循环中：

Ember.run(function(){
  // all call that results in asynchronous operations goes here
});

一旦完成，您的问题很可能就会消失！此外，确保在等待异步调用完成的异步调用之后使用“waitFor”或“andThen”函数（取决于测试框架）。如果有效，请告诉我。

使用Karma进行EmberJS测试 - 使用PhantomJS进行runloop错误，但不使用chrome
