java - Android Junit 测试卡在 "Launching: Creating source locator..."

Question

编辑
经过一番调试，我发现整个测试没有运行。但奇怪的是，它运行了几次，当我再次尝试时，它无法运行。在进度选项卡下，始终卡在“正在启动:正在创建源定位器...”，并且测试未执行。

我尝试重新启动 Eclipse，但无法让它工作。

我是 Android 测试的新手，我想生成触摸事件来测试 Android 应用程序中视频的暂停和播放。我使用Android测试框架选择视频并播放它，视频开始正​​常运行，但是触摸事件没有执行，测试也没有结束。我尝试调试，但测试运行时从未调用 touchlistener。我不确定为什么代码执行没有到达 MotionEvents 部分。非常感谢您的帮助!

public class VideoPlaybackTest extends ActivityInstrumentationTestCase2<MainActivity> {

private Activity activity;
private Fragment localvideosfragment;
private VideoPlayer videoplayer;
private ZoomState zoomstate;
private RenderView renderView;

public VideoPlaybackTest() {
    super(MainActivity.class);
}

@Before
public void setUp() throws Exception {
    super.setUp();

    setActivityInitialTouchMode(true);

    activity = getActivity();
    FragmentManager fragmentmanager = activity.getFragmentManager();
    localvideosfragment = fragmentmanager.findFragmentById(R.id.frame_container);
}

@Test
public void testVideoSelection() {

    activity.runOnUiThread(new Runnable() {
        public void run() {
            assertNotNull(localvideosfragment);
            View rootView = (View) localvideosfragment.getView();
            ListView videolist = (ListView) rootView.findViewById(R.id.list);
            assertNotNull(videolist);
            // Select video to play 
            videolist.performItemClick(videolist.getChildAt(0), 0, videolist.getChildAt(0).getId());
        }
    });

    // Wait for VideoPlayer Activity to be started
    ActivityMonitor monitor = getInstrumentation().addMonitor(VideoPlayer.class.getName(), null, false);
    Instrumentation instrumentation = getInstrumentation();
    instrumentation.waitForIdleSync();

    // get the started video player Activity
    videoplayer = (VideoPlayer) instrumentation.waitForMonitor(monitor);
    assertNotNull(videoplayer);

    // Get zoomstate and assert that video is playing 
    renderView = videoplayer.getRenderView();
    assertNotNull(renderView);
    zoomstate = renderView.getZoomState();
    assertNotNull(zoomstate);
    ROIState roistate = renderView.getROIState();
    Boolean isPlaying = roistate.isPlaying;
    assertTrue(zoomstate.isPlaying());
    assertTrue(isPlaying);

    // Obtain MotionEvent object
    long downTime = SystemClock.uptimeMillis();
    long eventTime = SystemClock.uptimeMillis();
    float x = 0.0f;
    float y = 0.0f;
    int metaState = 0;
    MotionEvent motionEventup = MotionEvent.obtain(
            downTime, 
            eventTime, 
            MotionEvent.ACTION_UP, 
            x, 
            y, 
            metaState
            );
    MotionEvent motionEventdown = MotionEvent.obtain(
            downTime, 
            eventTime, 
            MotionEvent.ACTION_DOWN, 
            x, 
            y, 
            metaState
            );

    renderView.dispatchTouchEvent(motionEventdown);
    renderView.dispatchTouchEvent(motionEventup);
    roistate = renderView.getROIState();
    isPlaying = roistate.isPlaying;
    zoomstate = renderView.getZoomState();
    Boolean state = zoomstate.isPlaying();
    assertFalse(state);
    assertFalse(isPlaying);
}

}

好吧，我找到了让它发挥作用的方法。我已从设备中卸载现有应用程序，然后重新开始。此后测试运行良好。
