### Question:
BattleDataLoader4Bitmap { public static BattleBitSetBullet getBattleBulletByName(String bulletName) { BattleBitSetBullet bullet = battleBullets.get(bulletName); if ( bullet != null ) { if ( BattleManager.getInstance().isUseDistributed() ) { return bullet; } else { return bullet.clone(); } } else { return null; } }  static boolean loadBattleMaps(); static ArrayList<BattleBitSetMap> getBattleMapList(); static BattleBitSetMap getRandomBattleMap(Battle battle); static BattleBitSetMap getBattleMapById(String mapId); static boolean loadBattleBullet(); static BattleBitSetBullet getBattleBulletByName(String bulletName); static Collection<BattleBitSetBullet> getBattleBullets(); static void main(String... args );  }### Answer:
@Test public void testGetBattleBulletByName() { GlobalConfig.getInstance().overrideProperty(GlobalConfigKey.deploy_data_dir, "../deploy/data"); boolean success = BattleDataLoader4Bitmap.loadBattleBullet(); assertTrue(success); BattleBitSetBullet bullet = BattleDataLoader4Bitmap.getBattleBulletByName("bullet_black"); System.out.println(bullet); assertNotNull(bullet); }
