### Question:
AAIServiceInstanceResources { public void createProject(Project project) { AAIResourceUri projectURI = AAIUriFactory.createResourceUri(AAIFluentTypeBuilder.business().project(project.getProjectName())); org.onap.aai.domain.yang.Project aaiProject = aaiObjectMapper.mapProject(project); injectionHelper.getAaiClient().createIfNotExists(projectURI, Optional.of(aaiProject)); }  boolean existsServiceInstance(ServiceInstance serviceInstance); void createServiceInstance(ServiceInstance serviceInstance, Customer customer); void createServiceSubscription(Customer customer); void deleteServiceInstance(ServiceInstance serviceInstance); void createProject(Project project); void createProjectandConnectServiceInstance(Project project, ServiceInstance serviceInstance); void createOwningEntity(OwningEntity owningEntity); boolean existsOwningEntity(OwningEntity owningEntity); boolean existsOwningEntityName(String owningEntityName); org.onap.aai.domain.yang.OwningEntity getOwningEntityByName(String owningEntityName); void connectOwningEntityandServiceInstance(OwningEntity owningEntity, ServiceInstance serviceInstance); void createOwningEntityandConnectServiceInstance(OwningEntity owningEntity,
            ServiceInstance serviceInstance); void updateOrchestrationStatusServiceInstance(ServiceInstance serviceInstance,
            OrchestrationStatus orchestrationStatus); void updateServiceInstance(ServiceInstance serviceInstance); boolean checkInstanceServiceNameInUse(ServiceInstance serviceInstance);  }### Answer:
@Test public void createProjectTest() { doReturn(new org.onap.aai.domain.yang.Project()).when(MOCK_aaiObjectMapper).mapProject(project); aaiServiceInstanceResources.createProject(project); verify(MOCK_aaiResourcesClient, times(1)).createIfNotExists(any(AAIResourceUri.class), any(Optional.class)); }
