### Question:
DocumentNominalLabelResourceFacadeImp extends CoreDBServiceFacadeImp<DocumentNominalLabel, Long> implements DocumentNominalLabelResourceFacade { @Override public List<DocumentNominalLabelDTO> getAllDocuments() throws PropertyNotSetException { logger.info("Received request for fetching all Documents!!!"); List<DocumentNominalLabelDTO> dtoList = new ArrayList<DocumentNominalLabelDTO>(); List<DocumentNominalLabel> list = getAll(); if (list != null && !list.isEmpty()) { for (DocumentNominalLabel doc : list) { DocumentNominalLabelDTO dto = new DocumentNominalLabelDTO(doc); dtoList.add(dto); } } logger.info("Done creating DTO list, size = " + dtoList.size()); return dtoList; } protected  DocumentNominalLabelResourceFacadeImp(); @Override void saveDocumentNominalLabel(DocumentNominalLabelDTO documentNominalLabel); @Override boolean foundDuplicate(DocumentNominalLabelDTO documentNominalLabel); @Override DocumentNominalLabelDTO addDocument(DocumentNominalLabelDTO doc); @Override DocumentNominalLabelDTO editDocument(DocumentNominalLabelDTO doc); @Override Integer deleteDocument(DocumentNominalLabelDTO doc); @Override List<DocumentNominalLabelDTO> findByCriteria(String columnName, Object value); @Override DocumentNominalLabelDTO findDocumentByPrimaryKey(DocumentNominalLabelIdDTO id); @Override boolean isDocumentExists(DocumentNominalLabelIdDTO id); @Override boolean isDocumentExists(Long id); @Override List<DocumentNominalLabelDTO> getAllDocuments(); @Override DocumentNominalLabelDTO findLabeledDocumentByID(Long id); @Override List<DocumentNominalLabelDTO> findLabeledDocumentListByID(Long id); @Override List<DocumentNominalLabelDTO> getLabeledDocumentCollectionForNominalLabel(Integer nominalLabelID); @Override void deleteDocumentNominalLabelByNominalLabel(Long nominalLabelID);  }### Answer:
@Test public void testGetAllDocuments() { try { List<DocumentNominalLabelDTO> result = documentNominalLabelResourceFacadeImp .getAllDocuments(); assertNotNull(result); assertTrue(result.size() >= 1); } catch (PropertyNotSetException ex) { logger.error("PropertyNotSetException while fetching all document nominal label "+ex.getMessage()); fail("getAllDocuments failed"); } }
