I need to write unit test for android media player, that verify that MediaPlayer's class method call or not.

@Override
public void setAssetPath(String path) throws IOException {
    if(!this.path.equals(path)){
        this.path = path;
        mediaPlayer.setDataSource(path);
    }
}

@Override
public void play() {
    if(mediaPlayer == null){
        return;
    }
    mediaPlayer.start();
}

@Override

        mediaPlayer.pause();
    }
}
