### Question:
SDNCVfModuleResources { public GenericResourceApiVfModuleOperationInformation deactivateVfModule(VfModule vfModule, GenericVnf vnf, ServiceInstance serviceInstance, Customer customer, CloudRegion cloudRegion, RequestContext requestContext, URI callbackURI) throws MapperException { return sdncRM.reqMapper(SDNCSvcOperation.VF_MODULE_TOPOLOGY_OPERATION, SDNCSvcAction.DEACTIVATE, vfModule, null, vnf, serviceInstance, customer, cloudRegion, requestContext, null, callbackURI); }  GenericResourceApiVfModuleOperationInformation assignVfModule(VfModule vfModule, VolumeGroup volumeGroup,
            GenericVnf vnf, ServiceInstance serviceInstance, Customer customer, CloudRegion cloudRegion,
            RequestContext requestContext, URI callbackURI); GenericResourceApiVfModuleOperationInformation unassignVfModule(VfModule vfModule, GenericVnf vnf,
            ServiceInstance serviceInstance, RequestContext requestContext, URI callbackURI); GenericResourceApiVfModuleOperationInformation deactivateVfModule(VfModule vfModule, GenericVnf vnf,
            ServiceInstance serviceInstance, Customer customer, CloudRegion cloudRegion, RequestContext requestContext,
            URI callbackURI); String queryVfModule(VfModule vfModule); GenericResourceApiVfModuleOperationInformation activateVfModule(VfModule vfModule, GenericVnf vnf,
            ServiceInstance serviceInstance, Customer customer, CloudRegion cloudRegion, RequestContext requestContext,
            URI callbackURI); GenericResourceApiVfModuleOperationInformation changeAssignVfModule(VfModule vfModule, GenericVnf vnf,
            ServiceInstance serviceInstance, Customer customer, CloudRegion cloudRegion, RequestContext requestContext,
            URI callbackURI);  }### Answer:
@Test public void deactivateVfModuleTest() throws MapperException { doReturn(sdncReq).when(vfModuleTopologyMapper).reqMapper(SDNCSvcOperation.VF_MODULE_TOPOLOGY_OPERATION, SDNCSvcAction.DEACTIVATE, vfModule, null, vnf, serviceInstance, customer, cloudRegion, requestContext, null, testURI); sdncVfModuleResources.deactivateVfModule(vfModule, vnf, serviceInstance, customer, cloudRegion, requestContext, testURI); verify(vfModuleTopologyMapper, times(1)).reqMapper(SDNCSvcOperation.VF_MODULE_TOPOLOGY_OPERATION, SDNCSvcAction.DEACTIVATE, vfModule, null, vnf, serviceInstance, customer, cloudRegion, requestContext, null, testURI); }
