### Question:
BBInputSetupMapperLayer { protected L3Network mapAAIL3Network(org.onap.aai.domain.yang.L3Network aaiL3Network) { L3Network network = modelMapper.map(aaiL3Network, L3Network.class); mapAllSubnetsIntoL3Network(aaiL3Network, network); mapAllCtagAssignmentsIntoL3Network(aaiL3Network, network); mapAllSegmentationAssignmentsIntoL3Network(aaiL3Network, network); mapAllAggregateRoutesIntoL3Network(aaiL3Network, network); network.setOrchestrationStatus(this.mapOrchestrationStatusFromAAI(aaiL3Network.getOrchestrationStatus())); return network; }  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(

            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 testMapAAIL3NetworkIntoL3Network() throws IOException { L3Network expected = mapper.readValue(new File(RESOURCE_PATH + "l3NetworkExpectedWithSubnet.json"), L3Network.class); org.onap.aai.domain.yang.L3Network aaiL3Network = mapper.readValue(new File(RESOURCE_PATH + "aaiL3NetworkInputWithSubnets.json"), org.onap.aai.domain.yang.L3Network.class); L3Network actual = bbInputSetupMapperLayer.mapAAIL3Network(aaiL3Network); assertThat(actual, sameBeanAs(expected)); }
