任何人都知道Async.asyncHandler()
如何工作以及Async.processOnEvent()
只能在[Before]方法中使用。(除了http://docs.flexunit.org/之外,任何人都知道一些有用的文档。)
我定义了一个名为HelloCompo(扩展Vbox)的MXML组件,该组件定义了一个名为hello()的函数,在hello()中发生了一个名为HelloEvent的客户事件(事件类型名为“hello”),并在另一个名为init()的函数侦听了该事件,我想测试是否正确调度该事件。所以我有以下测试:
var helloCompo = new HelloCompo();
helloCompo.hello();
helloCompo.addEventListener("hello", Async.asyncHandler(this, handleHello, 1000, null, handleTimeOut));
测试将始终执行handleTimeOut方法(意味着不调度HelloEvent,但是当helloCompo.hello()执行时,它真的发生了干扰,那么出了什么问题?)

我认为你需要在调用hello()之前添加你的事件监听器
