asp.net-mvc-3 - httpcontext.current.server.mappath と単体テスト

Question

dbfirst モデルで asp.net mvc3/razor を使用しています。登録後にxml形式の確認メールを送信します。単体テスト中にこの xml ファイルを読み取る必要があります。

アカウント管理者:

  Fds.ReadXml(HttpContext.Current.Server.MapPath("~/Files/ForgotPassword.xml"));

単体テスト:

 public void Saveuser()
         {
             RegisterModel model = new RegisterModel();
             FormCollection f = new FormCollection();
             List<MailModel> m = new List<MailModel>();
             HttpContext.Current = FakeHttpContext();
             m = user.GetMail().ToList();
             MailModel mmodel = new MailModel();
             mmodel = m[0];
           model.Name = "testuse11r9788";
          model.UserName = "test1user9878";
          model.Password = "1234567";
          model.ConfirmPassword = "1234567";
          model.Email = "testus11979@gmail.com";
          var controller = new AccountController(user,mail);
          var saveuser = controller.Register(model,f) as ViewResult;
          var saveActUser = (RegisterModel)saveuser.ViewData.Model;
          var saveExpUser = model;
           areuserEqual(saveExpUser, saveActUser);
         }

public static HttpContext FakeHttpContext()
        {

// httprequest に何を入力すればよいか教えてください????

  var httpRequest = new HttpRequest("", "http://localhost:mmmm/", "");
                 var stringWriter = new StringWriter();
                 var httpResponce = new HttpResponse(stringWriter);
                var httpContext = new HttpContext(httpRequest, httpResponce);

            var sessionContainer = new HttpSessionStateContainer("id", new SessionStateItemCollection(),
                                                    new HttpStaticObjectsCollection(), 10, true,
                                                    HttpCookieMode.AutoDetect,
                                                    SessionStateMode.InProc, false);

            httpContext.Items["AspSession"] = typeof(HttpSessionState).GetConstructor(
                                        BindingFlags.NonPublic | BindingFlags.Instance,
                                        null, CallingConventions.Standard,
                                        new[] { typeof(HttpSessionStateContainer) },
                                        null)
                                .Invoke(new object[] { sessionContainer });

            return httpContext;
        }
