### Question:
ModelNominalLabelResourceFacadeImp extends CoreDBServiceFacadeImp<ModelNominalLabel, Long> implements ModelNominalLabelResourceFacade { @Override public List<ModelNominalLabelDTO> getAllModelNominalLabels() { List<ModelNominalLabelDTO> dtoList = new ArrayList<ModelNominalLabelDTO>(); try { List<ModelNominalLabel> list = this.getAll(); if (list != null && !list.isEmpty()) { logger.info("Fetched list size: " + list.size()); for (ModelNominalLabel m : list) { dtoList.add(new ModelNominalLabelDTO(m)); } } return dtoList; } catch (Exception e) { logger.error("Error in getAllModelNominalLabels."); return null; } } 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 testGetAllModelNominalLabels() { List<ModelNominalLabelDTO> modelNominalLabelDTOs = modelNominalLabelResourceFacadeImp.getAllModelNominalLabels(); assertNotNull(modelNominalLabelDTOs); assertTrue(modelNominalLabelDTOs.size() >= 1); }
