### Question:
ModelNominalLabelResourceFacadeImp extends CoreDBServiceFacadeImp<ModelNominalLabel, Long> implements ModelNominalLabelResourceFacade { @Override public Boolean isModelNominalLabelExists(Long nominalLabelID) throws PropertyNotSetException { return (getModelNominalLabelByID(nominalLabelID) != null) ? true : false; } protected  ModelNominalLabelResourceFacadeImp(); @Override List<ModelNominalLabelDTO> getAllModelNominalLabels(); @Override List<ModelNominalLabelDTO> getAllModelNominalLabelsByModelID(Long modelID, String crisisCode); @Override void saveModelNominalLabel(ModelNominalLabelDTO modelNominalLabel); @Override ModelNominalLabelDTO addModelNominalLabel(ModelNominalLabelDTO modelNominalLabel); @Override ModelNominalLabelDTO editModelNominalLabel(ModelNominalLabelDTO modelNominalLabel); @Override Integer deleteModelNominalLabel(ModelNominalLabelDTO modelNominalLabel); @Override ModelNominalLabelDTO getModelNominalLabelByID(Long nominalLabelID); @Override Boolean isModelNominalLabelExists(Long nominalLabelID); @Override void deleteModelNominalLabelByModelID(Long modelID);  }### Answer:
@Test public void testIsModelNominalLabelExists() { try { boolean exists = modelNominalLabelResourceFacadeImp.isModelNominalLabelExists(nominalLabelDTO.getNominalLabelId()); assertTrue("testIsModelNominalLabelExists", exists); } catch (PropertyNotSetException e) { logger.error("PropertyNotSetException while executing testIsModelNominalLabelExists "+e.getMessage()); } }
