### Question:
BBInputSetupMapperLayer { protected org.onap.so.bpmn.servicedecomposition.bbobjects.InstanceGroup mapAAIInstanceGroupIntoInstanceGroup( org.onap.aai.domain.yang.InstanceGroup aaiInstanceGroup) { return modelMapper.map(aaiInstanceGroup, org.onap.so.bpmn.servicedecomposition.bbobjects.InstanceGroup.class); }  Customer mapAAICustomer(org.onap.aai.domain.yang.Customer customerAAI); ServiceSubscription mapAAIServiceSubscription(
            org.onap.aai.domain.yang.ServiceSubscription serviceSubscriptionAAI); NetworkPolicy mapAAINetworkPolicy(org.onap.aai.domain.yang.NetworkPolicy aaiNetworkPolicy); ModelInfoServiceInstance mapCatalogServiceIntoServiceInstance(Service service); ServiceInstance mapAAIServiceInstanceIntoServiceInstance(
            org.onap.aai.domain.yang.ServiceInstance aaiServiceInstance); OrchestrationStatus mapOrchestrationStatusFromAAI(String orchestrationStatus); RequestContext mapRequestContext(RequestDetails requestDetails); RouteTableReference mapAAIRouteTableReferenceIntoRouteTableReference(
            org.onap.aai.domain.yang.RouteTableReference aaiRouteTableReference); Configuration mapAAIConfiguration(org.onap.aai.domain.yang.Configuration configurationAAI); NetworkResourceCustomization mapCollectionNetworkResourceCustToNetworkResourceCust(
            CollectionNetworkResourceCustomization collectionNetworkResourceCust); Vnfc mapAAIVnfc(org.onap.aai.domain.yang.Vnfc vnfcAAI); VpnBinding mapAAIVpnBinding(org.onap.aai.domain.yang.VpnBinding aaiVpnBinding); RouteTarget mapAAIRouteTarget(org.onap.aai.domain.yang.RouteTarget aaiRouteTarget);  }### Answer:
@Test public void testMapAAIInstanceGroupIntoInstanceGroup() throws JsonParseException, JsonMappingException, IOException { org.onap.aai.domain.yang.InstanceGroup aaiInstanceGroup = mapper.readValue( new File(RESOURCE_PATH + "InstanceGroupInput.json"), org.onap.aai.domain.yang.InstanceGroup.class); org.onap.so.bpmn.servicedecomposition.bbobjects.InstanceGroup expectedInstanceGroup = mapper.readValue(new File(RESOURCE_PATH + "InstanceGroupExpected.json"), org.onap.so.bpmn.servicedecomposition.bbobjects.InstanceGroup.class); org.onap.so.bpmn.servicedecomposition.bbobjects.InstanceGroup actualInstanceGroup = bbInputSetupMapperLayer.mapAAIInstanceGroupIntoInstanceGroup(aaiInstanceGroup); assertThat(actualInstanceGroup, sameBeanAs(expectedInstanceGroup)); }
