Android中使用AndroidTestCase的方法实例

Android 使用 AndroidTestCase 的步骤
1.新建一个类继承 AndroidTestCase

public class TestAudio extends AndroidTestCase {  

    private AudioManager mAudioManager;  

    private boolean mUseFixedVolume;  

    private final static long TIME_TO_PLAY = 2000;  

    private final static int MP3_TO_PLAY = R.raw.testmp3;  

      

    @Override  

    protected void setUp() throws Exception {  

        // TODO Auto-generated method stub  

        super.setUp();  

          

    }  

      

    public void testmp3(){  

        MediaPlayer mp = MediaPlayer.create(mContext, MP3_TO_PLAY);  

        mp.setAudioStreamType(STREAM_MUSIC);  

        mp.setLooping(true);  

        mp.start();  

        try {  

            Thread.sleep(20*1000);  

        } catch (InterruptedException e) {  

            // TODO Auto-generated catch block  

            e.printStackTrace();  

        }  

    }  

}

    </application>  

    <!-- 与application标签同级的位置添加 -->
