Question

I am creating a test suite for my android application and have this setUp method

    private static final String TAG_NAME = "TESTING_SUITE";
        public TestingMusicDAO musicDAO;
        public List<Song> songs;
        public Instrumentation instr;
        MusicService musicService;
    @Override
    public void setUp() throws Exception {
        instr = this.getInstrumentation();
        Log.d(TAG_NAME, "Setting up testing songs");
        musicDAO = new TestingMusicDAO(instr.getContext());
        musicService = new MusicServiceImpl(musicDAO);
        musicDAO.getAllSongsFromFile();
        songs = musicDAO.getAllSongs();
        for(Song song : songs)
            Log.d( TAG_NAME, song.toString() );
     }

And then have these tests which are created by a python tool from a text file

public void test1() {
    List<Song> testPlaylist;
    String testArtist = ("The Beatles");
    String actualArtist = ("TheBeatles"); 
    testPlaylist = testingPlaySongsByKeyword(testArtist);
    if(testPlaylist.isEmpty()){
        fail("No Songs Were Found");
    } else {
        for( Song loopsongs : testPlaylist){
            if (!(loopsongs.getArtist().equals(actualArtist))){
                fail("Song Doesnt Contain the artist" + actualArtist + "... Contains ->" + loopsongs.getArtist());
            }
        }
   }
}

and every time one of these gets called the musicDAO is regenerated. How can I stop the setup method from being called

Answer 1

You don’t. The design of JUnit is that setUp() and tearDown() are done once per test. If you want it done per class, do it in the constructor. Just make sure that you don’t alter anything inside the classes. The reason for doing it once per test is to make sure all tests start with the same data.
