c# - How to mock(rhino.mocks) response object from base.SendAsync() in MVC4.5 Web API handler SendAsync() method -

i have write unit test on asp.net mvc web api controller rhino.mock have handler named ahandler.cs inherts system.net.http.httpclienthandler class. singnature sendasync method of ahandler.cs followings :

protected override task<httpresponsemessage> sendasync(httprequestmessage request, cancellationtoken cancellationtoken) { .....  var response = base.sendasync(request, cancellationtoken).result;   if (response.issuccessstatuscode)  {    .....  } } 

the base keyword above means httpclienthandler , sendasync() method "protected"!!! try mock object "base.sendasync(request, cancellationtoken).result" , got hand-made response result wanted. seems rhino mocks can't see "base" keyword when wrote followings code :

var mockbase = mockrepository.generatemock<ahandler>; mockbase.stub(x => x.base <=== can't see base keyword                  ^^^^^ 

so change way , try mock httpclienthandler class

var mockbase = mockrepository.generatemockhttpclienthandler>; mockbase.stub(x => x.  <== can't see sendasync() method, becase protected !! 

now suffer in !! can give me advice how made custom response in mvc handler ?! !!

why want mock handler in first place ? can inject specific dummy implementation tests. handler return new httpresponse message expected tests.

public class mydummyhttphandler : delegatinghandler {   httpresponsemessage response;    public mydummyhttphandler(httpresponsemessage response)   {     this.response = response;   }    protected override task<httpresponsemessage> sendasync(httprequestmessage request,    cancellationtoken cancellationtoken)   {     .....     taskcompletionsource<httpresponsemessage> tsc = new taskcompletionsource<httpresponsemessage>();     tsc.setresult(this.response);      return tsc.task;   } }
