### Question:
VnfAdapterVolumeGroupResources { public CreateVolumeGroupRequest createVolumeGroupRequest(RequestContext requestContext, CloudRegion cloudRegion, OrchestrationContext orchestrationContext, ServiceInstance serviceInstance, GenericVnf genericVnf, VolumeGroup volumeGroup, String sdncVfModuleQueryResponse) throws IOException { return vnfAdapterObjectMapper.createVolumeGroupRequestMapper(requestContext, cloudRegion, orchestrationContext, serviceInstance, genericVnf, volumeGroup, sdncVfModuleQueryResponse); }  CreateVolumeGroupRequest createVolumeGroupRequest(RequestContext requestContext, CloudRegion cloudRegion,
            OrchestrationContext orchestrationContext, ServiceInstance serviceInstance, GenericVnf genericVnf,
            VolumeGroup volumeGroup, String sdncVfModuleQueryResponse); DeleteVolumeGroupRequest deleteVolumeGroupRequest(RequestContext requestContext, CloudRegion cloudRegion,
            ServiceInstance serviceInstance, VolumeGroup volumeGroup);  }### Answer:
@Test public void test_createVolumeGroup() throws Exception { volumeGroup.setOrchestrationStatus(OrchestrationStatus.ASSIGNED); CreateVolumeGroupRequest createVolumeGroupRequest = new CreateVolumeGroupRequest(); createVolumeGroupRequest.setCloudSiteId("cloudSiteId"); CreateVolumeGroupResponse expectedCreateVolumeGroupResponse = new CreateVolumeGroupResponse(); expectedCreateVolumeGroupResponse.setVolumeGroupStackId("volumeGroupStackId"); expectedCreateVolumeGroupResponse.setVolumeGroupCreated(true); String sdncVfModuleQueryResponse = "sdncVfModuleQueryResponse"; doReturn(createVolumeGroupRequest).when(MOCK_vnfAdapterObjectMapper).createVolumeGroupRequestMapper( requestContext, cloudRegion, orchestrationContext, serviceInstance, genericVnf, volumeGroup, sdncVfModuleQueryResponse); CreateVolumeGroupRequest actualCreateVolumeGroupResponse = vnfAdapterVolumeGroupResources.createVolumeGroupRequest(requestContext, cloudRegion, orchestrationContext, serviceInstance, genericVnf, volumeGroup, sdncVfModuleQueryResponse); verify(MOCK_vnfAdapterObjectMapper, times(1)).createVolumeGroupRequestMapper(requestContext, cloudRegion, orchestrationContext, serviceInstance, genericVnf, volumeGroup, sdncVfModuleQueryResponse); assertThat(createVolumeGroupRequest, Matchers.sameBeanAs(actualCreateVolumeGroupResponse)); }
