### Question:
AAICreateTasks { public void connectVnfToTenant(BuildingBlockExecution execution) { try { GenericVnf vnf = extractPojosForBB.extractByKey(execution, ResourceKey.GENERIC_VNF_ID); aaiVnfResources.connectVnfToTenant(vnf, execution.getGeneralBuildingBlock().getCloudRegion()); } catch (Exception ex) { exceptionUtil.buildAndThrowWorkflowException(execution, 7000, ex); } }  void createServiceInstance(BuildingBlockExecution execution); void createServiceSubscription(BuildingBlockExecution execution); void createProject(BuildingBlockExecution execution); void createOwningEntity(BuildingBlockExecution execution); void createVnf(BuildingBlockExecution execution); void createPnf(BuildingBlockExecution execution); void createPlatformForNetwork(BuildingBlockExecution execution); void createPlatform(BuildingBlockExecution execution); List<String> splitCDL(String str); void createLineOfBusiness(BuildingBlockExecution execution); void createLineOfBusinessForNetwork(BuildingBlockExecution execution); void createVolumeGroup(BuildingBlockExecution execution); void createVfModule(BuildingBlockExecution execution); void connectVfModuleToVolumeGroup(BuildingBlockExecution execution); void createNetwork(BuildingBlockExecution execution); void createCustomer(BuildingBlockExecution execution); void createNetworkCollection(BuildingBlockExecution execution); void createNetworkCollectionInstanceGroup(BuildingBlockExecution execution); void connectNetworkToTenant(BuildingBlockExecution execution); void connectNetworkToCloudRegion(BuildingBlockExecution execution); void connectVnfToCloudRegion(BuildingBlockExecution execution); void connectVnfToTenant(BuildingBlockExecution execution); void connectNetworkToNetworkCollectionServiceInstance(BuildingBlockExecution execution); void connectNetworkToNetworkCollectionInstanceGroup(BuildingBlockExecution execution); void createConfiguration(BuildingBlockExecution execution); void createInstanceGroupVnf(BuildingBlockExecution execution); void createNetworkPolicies(BuildingBlockExecution execution);  }### Answer:
@Test public void connectVnfTenantTest() throws Exception { gBBInput = execution.getGeneralBuildingBlock(); doNothing().when(aaiVnfResources).connectVnfToTenant(genericVnf, gBBInput.getCloudRegion()); aaiCreateTasks.connectVnfToTenant(execution); verify(aaiVnfResources, times(1)).connectVnfToTenant(genericVnf, gBBInput.getCloudRegion()); }
