### Question:
KunderaPersistenceProviderUtil implements ProviderUtil { @Override public LoadState isLoaded(Object paramObject) { return PersistenceUtilHelper.isLoaded(paramObject); } KunderaPersistenceProviderUtil(KunderaPersistence provider); @Override LoadState isLoadedWithoutReference(Object paramObject, String paramString); @Override LoadState isLoadedWithReference(Object paramObject, String paramString); @Override LoadState isLoaded(Object paramObject);  }### Answer:
@Test public void testIsLoaded() { KunderaPersistenceProviderUtil providerUtil = new KunderaPersistenceProviderUtil(persistence); LoadState state = providerUtil.isLoaded(null); Assert.assertNotNull(state); Assert.assertEquals(LoadState.NOT_LOADED, state); }
