我使用 Kinect Toolbox 的 KinectRecorder 类录制了 Kinect 骨架流。我想使用 Kinect 工具箱中的 KinectReplay 类在单元测试中重播整个录制的文件。录音作为嵌入式资源添加到我的测试项目中（可能不相关，但作为下面代码的解释）。

我面临的问题是 KinectReplay 类（特别是 ReplaySystem 类）使用 C# 的 Task Parallel 库来播放骨架帧。无需任何修改，这意味着我的单元测试会立即从对 KinectReplay.Start() 的调用中返回。

对 Kinect 工具箱没有修改：

[Test]
public void CanPlaybackDataInNunitTest()
{
    Type thisType = this.GetType();
    Stream resourceStream =
        thisType.Assembly.GetManifestResourceStream(
        thisType.Namespace +".TestDataFiles.testfile.replay");
    KinectReplay kinectReplay = new KinectReplay(resourceStream);

    kinectReplay.SkeletonFrameReady += (sender, args) =>
        { //breakpoint gets set on this brace, never hit
            //test
        };
    kinectReplay.Start();

    // ...
}

我尝试过：将“ReplayFinished”.net 事件添加到 KinectReplay 类，将 AutoResetEvent 添加到 KinectReplay 类，以及（如下所示）使用事件处理程序和 WaitHandles 的混合解决方案：

public void CanPlaybackDataInNunitTest()
{
    Type thisType = this.GetType();
    Stream resourceStream =
        thisType.Assembly.GetManifestResourceStream(
        thisType.Namespace +".TestDataFiles.testfile.replay");
    KinectReplay kinectReplay = new KinectReplay(resourceStream);

    // Initialize a wait handle to know when replay ends
    AutoResetEvent isFinishedWaitHandle = new AutoResetEvent(false);

    kinectReplay.SkeletonFrameReady += (sender, args) =>
        { // breakpoint here, never hit
            //test
        };

    kinectReplay.Start();

    // subscribe to a new event i added to the KinectReplay class
    // This event is invoked when the IsFinished property becomes true
    kinectReplay.ReplayFinished += (o, a) =>
        {
            isFinishedWaitHandle.Set();
        };

    // the unit test will block here and will not return until the 5 minute timeout
    // I know that skeleton data is present within two seconds in the replay data
    isFinishedWaitHandle.WaitOne(new TimeSpan(0, 0, 5, 0));

    // ....
}

如果将 KinectToolbox 用于在带有回放数据的单元测试中执行算法的目标是不现实的，我会考虑其他解决方案！
