### Question:
AAICreateTasks { public void connectVfModuleToVolumeGroup(BuildingBlockExecution execution) { try { GenericVnf vnf = extractPojosForBB.extractByKey(execution, ResourceKey.GENERIC_VNF_ID); VfModule vfModule = extractPojosForBB.extractByKey(execution, ResourceKey.VF_MODULE_ID); VolumeGroup volumeGroup = null; try { volumeGroup = extractPojosForBB.extractByKey(execution, ResourceKey.VOLUME_GROUP_ID); } catch (BBObjectNotFoundException e) { logger.info("VolumeGroup not found. Skipping Connect between VfModule and VolumeGroup"); } if (volumeGroup != null) { logger.debug("Connecting VfModule to VolumGroup"); aaiVfModuleResources.connectVfModuleToVolumeGroup(vnf, vfModule, volumeGroup, 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 connectVfModuleToVolumeGroupTest() throws Exception { doNothing().when(aaiVfModuleResources).connectVfModuleToVolumeGroup(genericVnf, vfModule, volumeGroup, cloudRegion); aaiCreateTasks.connectVfModuleToVolumeGroup(execution); verify(aaiVfModuleResources, times(1)).connectVfModuleToVolumeGroup(genericVnf, vfModule, volumeGroup, cloudRegion); }
