### Question:
MapTilePersisterModel extends FeatureAbstract implements MapTilePersister { @Override public void prepare(FeatureProvider provider) { super.prepare(provider); map = provider.getFeature(MapTileSurface.class); } MapTilePersisterModel(); @Override void prepare(FeatureProvider provider); @Override void addListener(MapTilePersisterListener listener); @Override void removeListener(MapTilePersisterListener listener); @Override void save(FileWriting output); @Override void load(FileReading input);  }### Answer:
@Test void testConstructor() { final MapTile map = new MapTileGame(); final MapTilePersister mapPersister = new MapTilePersisterModel(); assertNotNull(mapPersister); mapPersister.prepare(map); }
