### Question:
BBInputSetupMapperLayer { public NetworkPolicy mapAAINetworkPolicy(org.onap.aai.domain.yang.NetworkPolicy aaiNetworkPolicy) { return modelMapper.map(aaiNetworkPolicy, NetworkPolicy.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 testMapAAINetworkPolicy() throws JsonParseException, JsonMappingException, IOException { NetworkPolicy expectedNetworkPolicy = mapper.readValue(new File(RESOURCE_PATH + "NetworkPolicy.json"), NetworkPolicy.class); org.onap.aai.domain.yang.NetworkPolicy aaiNetworkPolicy = new org.onap.aai.domain.yang.NetworkPolicy(); aaiNetworkPolicy.setNetworkPolicyId("networkPolicyId"); aaiNetworkPolicy.setNetworkPolicyFqdn("networkPolicyFqdn"); aaiNetworkPolicy.setHeatStackId("heatStackId"); aaiNetworkPolicy.setResourceVersion("resourceVersion"); NetworkPolicy actualNetworkPolicy = bbInputSetupMapperLayer.mapAAINetworkPolicy(aaiNetworkPolicy); assertThat(actualNetworkPolicy, sameBeanAs(expectedNetworkPolicy)); }
