如何使用SequenceRunner与FlexUnit4

Question

在 FlexUnit wiki 我读过有关的非常有趣的SequenceRunner这是贡献的Fluint人。现在我试图运行一个试验，这是非常相似的例子，但是在执行的运行()方法SequenceRunner实例，我得到这个例外：

    Cannot add asynchronous functionality to methods defined by Test,Before or After that are not marked async
Error: Cannot add asynchronous functionality to methods defined by Test,Before or After that are not marked async
    at org.flexunit.async::AsyncLocator$/getCallableForTest()[C:\Users\dmoor e\Documents\_Production\Flex Unit 4\GIT\FlexUnit4\src\org\flexunit\async\AsyncLocator.as:82]

    at org.fluint.sequence::SequenceRunner/run()[C:\Users\dmoore\Documents\_ Production\Flex Unit 4\GIT\FlexUnit4\src\org\fluint\sequence\SequenceRunner.as:124]

有人使用的SequenceRunner与FlexUnit4。[测试(异)]批注已经存在。

Answer 1

感谢迈克尔Labriola，谁回答我的问题 Adobe论坛 我终于能够使它运行。注意，该文件 SequenceRunner 在维基 已经过时和部分地是错误的。

1. 不继承的任何测试用例类。
2. 跳过asyncHandler为 CREATION_COMPLETE 在安装。而不是添加一个 SequenceWaiter 在试验中，等待 CREATION_COMPLETE 事件组件
3. 试验必须以标记为异步试验，所以加入的 [Test(async)] 元数据以测试情况下使用 SequenceRunner.

Answer 2

下面是一个完整的，非常简单的例子测试用例类。

package test
{
    import flash.events.Event;

    import org.flexunit.asserts.assertEquals;

    import org.fluint.sequence.SequenceRunner;
    import org.fluint.sequence.SequenceWaiter;

    public class test_case
    {
        [Test(async)]
        public function test_function():void
        {
            var counter:Object = { count: 0}
            var sr:SequenceRunner = new SequenceRunner(this);
            sr.addStep(new SequenceWaiter(new TestWaiterTarget(counter), "myEvent", 50000));
            sr.addStep(new SequenceWaiter(new TestWaiterTarget(counter), "myEvent", 5000))
            sr.addAssertHandler(test_function_handler, counter);
            sr.run();
        }

        private function test_function_handler(event:Event, passthroughData:*):void
        {
            assertEquals(passthroughData.count, 2);
        }
    }
}

import flash.events.Event;
import flash.events.EventDispatcher;
import flash.events.TimerEvent;
import flash.utils.Timer;

class TestWaiterTarget extends EventDispatcher
{
    var timer:Timer = new Timer(250, 1);

    private var _counter:Object;

    public function TestWaiterTarget(counter)
    {
        _counter = counter;
        timer.addEventListener(TimerEvent.TIMER_COMPLETE, timer_timerCompleteHandler);
        timer.start();
    }

    private function timer_timerCompleteHandler(event:TimerEvent):void
    {
        _counter.count++;
        dispatchEvent(new Event("myEvent"));
    }
}
