处理客户事件的Flexunit和async.asynchandler（）

Question

任何人都知道如何 Async.asyncHandler() 工作和如果 Async.processOnEvent() 只能在[之前]方法中使用。（任何人都知道一些有用的文档 http://docs.flexunit.org/).

我定义了一个名为hellocompo（扩展Vbox）的MXML组件，并且该组件在Hello（）中定义了名为Hello（）的函数，分配了一个名为HelloEvent的客户事件（事件类型恰好名为“ Hello hello”），并在另一个名为名为的函数中init（）收听了事件，我想测试该事件是否正确派遣。因此，我的测试以下是：

var hellocompo = new hellocompo（）;

helloCompo.hello();

helloCompo.addEventListener("hello", Async.asyncHandler(this, handleHello, 1000, null, handleTimeOut));

该测试总是会引起Handletimeout方法（意味着HelloEvent没有派遣，但是当Hellocompo.hello（）concute concute时，它确实分配了，所以怎么了？）

package flexUnitTests
{
    import flash.events.Event;

    import org.flexunit.asserts.assertTrue;
    import org.flexunit.asserts.fail;
    import org.flexunit.async.Async;

    public class HelloTest
    {       
        private var helloCompo:HelloCompo;

        [Before]
        public function setUp():void
        {
            helloCompo = new HelloCompo();
        }

        [After]
        public function tearDown():void
        {
            helloCompo = null;
        }

        [Test(async)]
        public function testHello():void
        {
            var handler:Function = Async.asyncHandler(this, helloHandler, 300, null, helloFailed);
            helloCompo.addEventListener("hello", handler);
            helloCompo.hello();
        }

        private function helloHandler(event:Event, passThroughObject:Object):void
        {
            //assert somthing
        }

        private function helloFailed(event:Event, passThroughObject:Object):void
        {
            fail("hello not dispatched");
        }


    }
}

hellocompo.as

package
{
    import flash.events.Event;
    import flash.events.EventDispatcher;
    import flash.events.IEventDispatcher;

    public class HelloCompo extends EventDispatcher
    {
        public function HelloCompo(target:IEventDispatcher=null)
        {
            super(target);
        }

        public function hello():void
        {
            dispatchEvent(new Event("hello"));
        }
    }
}

我认为您需要在调用Hello（）之前添加活动侦听器
