PROSAGA码农传奇-maven-使用Gitlab CI和Junit测试媒体播放器

<div class =“post-text”itemprop =“text”>
  <P>
    解：
我们没有处理过2个问题。首先，虚拟监视器的大小为1366x768，而用户界面的初始化大小为1300x900。因此无法到达播放/暂停按钮。
第二个错误是，媒体播放器需要更多时间在跑步者中进行初始化。因此，在媒体播放器初始化之后，并且在状态应该交换到播放之后，需要循环来等待媒体播放器交换。以下设置方法为我们解决了问题：

    <code>
        @Before
  public void setup() throws Exception {
    media = new Media(getClass().getResource("small.mp4").toString());
    mediaPlayer1 = new MediaPlayer(media);
    mediaPlayer1.setOnError(() -> fail("media error" + mediaPlayer1.getError().toString()));
    int retries = 0;
    while (mediaPlayer1.getStatus() != MediaPlayer.Status.READY) {
      System.out
          .println("media player not yet READY - current status: " + mediaPlayer1.getStatus());
      sleep(100);
      retries++;
      if (retries > 10) {
        fail("waited too long for media player to get READY");
      }   
    }   
    mediaView1 = find("#mediaView1");
    mediaView1.setMediaPlayer(mediaPlayer1);
    mediaPlayer1.play();
    retries = 0;
    while (mediaPlayer1.getStatus() != MediaPlayer.Status.PLAYING) {
      System.out
          .println("media player not yet PLAYING - current status: " + mediaPlayer1.getStatus());
      sleep(100);
      retries++;
      if (retries > 10) {
        fail("waited too long for media player to get PLAYING");
      }   
    }   
  }

    这个gitlab ci是必需的：
