OwnedEntityService { public EOwnedEntity create(final EOwnedEntity e) throws GmsGeneralException { if (configService.isMultiEntity()) { return entityRepository.save(e); } throw GmsGeneralException.builder() .messageI18N("entity.add.not_allowed") .finishedOK(true).httpStatus(HttpStatus.CONFLICT) .build(); }  EOwnedEntity createDefaultEntity(); EOwnedEntity create(final EOwnedEntity e);  }### Answer:
@Test public void create() { boolean initialIsM = configService.isMultiEntity(); if (!initialIsM) { configService.setIsMultiEntity(true); } try { final EOwnedEntity e = service.create(EntityUtil.getSampleEntity()); assertNotNull(e); Optional<EOwnedEntity> er = repository.findById(e.getId()); assertTrue(er.isPresent()); assertEquals(e, er.get()); } catch (GmsGeneralException e) { LOGGER.error(e.getLocalizedMessage()); fail("Entity could not be created"); } if (!initialIsM) { configService.setIsMultiEntity(false); } }
