How to mock WebOperationContext for unit testing?

I am trying to get the unit test (more integration test) written GetAwesomeResultsAsXml()for the next WCF boot service.
How do I feel about the WebOperationContextmocking aspect?
What would be a better approach?

public class AwesomeRestService : AwesomeRestServiceBase, IAwesomeRestService
    {
        public AwesomeSearchResults<AwesomeProductBase> GetAwesomeResultsAsXml()
        {
            return GetResults();
        }

        private static AwesomeSearchResults<AwesomeProductBase> GetResults()
        {
            var searchContext = AwesomeSearchContext
                               .Parse(WebOperationContext.Current);
            ..............
            ..............
            ..............
        }


    }

[ServiceContract]
    public interface IAwesomeRestService
    {
        [OperationContract]
        [WebInvoke(Method = "GET", ResponseFormat = WebMessageFormat.Xml,
        BodyStyle =  WebMessageBodyStyle.Bare,
            UriTemplate = "/search/xml")]
        AwesomeQueryResults<AwesomeProductBase> GetAwesomeResultsAsXml();


    }







public class AwesomeSearchContext
        {
            ................
            ................
            ................
             public static AwesomeSearchContext Parse 
                                           (WebOperationContext operationContext)
            {
                return WebOperationContext.Current != null ? new     
 AwesomeSearchContext(operationContext.IncomingRequest.UriTemplateMatch.QueryParameters) : null;
            }
        }

I met the same problem. I want the unit test WCF service function (for the IOauth2 interface, as shown below) without IIS. This is a piece of code to prepare.

// Prepare WebOperationContext
var factory = new ChannelFactory<IOauth2>(
    new WebHttpBinding(),
    new EndpointAddress("http://localhost:80"));

OperationContext.Current = new OperationContext(factory.CreateChannel() as IContextChannel);
Debug.Assert(WebOperationContext.Current != null);

I followed Sanjay and tried the fake MS framework,

First of all, you should open "Solution Explorer > your test project > Reference"=> right-click the "System.ServiceModel.Web"=>press "add Fakes Assembly"

Reference:

using Microsoft.QualityTools.Testing.Fakes;
using System.ServiceModel.Web.Fakes;

Example:

using (ShimsContext.Create())
{
    var response = new ShimOutgoingWebResponseContext();
    var request = new ShimIncomingWebRequestContext();

    var ctx_hd = new WebHeaderCollection();
    ctx_hd.Add("myCustomHeader", "XXXX");
    request.HeadersGet = () => ctx_hd;

    var ctx = new ShimWebOperationContext
    {
        OutgoingResponseGet = () => response,
        IncomingRequestGet = () => request
    };
    ShimWebOperationContext.CurrentGet = () => ctx;

    //Test your code here...
}

WebOperationContext.Current.IncomingRequest.Headers [ "myCustomHeader" ] WCF.

, MS Fakes, .

using (ShimsContext.Create())
        {

            var response = new ShimOutgoingWebResponseContext();
            var ctx = new ShimWebOperationContext
            {
                OutgoingResponseGet = () => response
            };

            ShimWebOperationContext.CurrentGet = () => ctx;

            try
            {
                ParameterInspector.BeforeCall("operationName", new string[]{"some_argument"} );
            }
            catch (Exception e)
            {
                Assert.IsNull(e);
            }
        }
