### Question:
BBInputSetupMapperLayer { public RequestContext mapRequestContext(RequestDetails requestDetails) { RequestContext context = new RequestContext(); if (null != requestDetails.getRequestInfo()) { modelMapper.map(requestDetails.getRequestInfo(), context); } org.onap.so.serviceinstancebeans.RequestParameters requestParameters = requestDetails.getRequestParameters(); if (null != requestParameters) { context.setSubscriptionServiceType(requestParameters.getSubscriptionServiceType()); context.setRequestParameters(this.mapRequestParameters(requestDetails.getRequestParameters())); context.setUserParams(this.mapNameValueUserParams(requestDetails.getRequestParameters())); } if (requestDetails.getConfigurationParameters() != null) { context.setConfigurationParameters(requestDetails.getConfigurationParameters()); } return context; }  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(

@Test public void testMapRequestContext() throws IOException { RequestContext expected = mapper.readValue(new File(RESOURCE_PATH + "RequestContextExpected.json"), RequestContext.class); RequestDetails requestDetails = mapper .readValue(new File(RESOURCE_PATH + "RequestDetailsInput_mapReqContext.json"), RequestDetails.class); RequestContext actual = bbInputSetupMapperLayer.mapRequestContext(requestDetails); assertThat(actual, sameBeanAs(expected)); }
