### Question:
BBInputSetupMapperLayer { protected RequestParameters mapRequestParameters( org.onap.so.serviceinstancebeans.RequestParameters requestParameters) { RequestParameters requestParams = new RequestParameters(); requestParams.setaLaCarte(requestParameters.getALaCarte()); requestParams.setUsePreload(requestParameters.getUsePreload()); requestParams.setSubscriptionServiceType(requestParameters.getSubscriptionServiceType()); requestParams.setUserParams(requestParameters.getUserParams()); requestParams.setPayload(requestParameters.getPayload()); return requestParams; }  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(

            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 testMapRequestParameters() throws IOException { RequestDetails requestDetails = mapper .readValue(new File(RESOURCE_PATH + "RequestDetailsInput_mapReqContext.json"), RequestDetails.class); RequestParameters actual = bbInputSetupMapperLayer.mapRequestParameters(requestDetails.getRequestParameters()); assertEquals(actual.getUsePreload(), requestDetails.getRequestParameters().getUsePreload()); assertEquals(actual.getSubscriptionServiceType(), requestDetails.getRequestParameters().getSubscriptionServiceType()); assertEquals(actual.getPayload(), requestDetails.getRequestParameters().getPayload()); }
