在进行单元测试时，Cookie在类库中不可用

Question

我正在为我的mvc应用程序进行单元测试。它包括许多类库。我已经使用NSubstitute模拟了单元测试项目中的http上下文并创建了cookie。但是在调试源代码时，它在类库中不可用。我们如何在类库中获取cookie？

单元测试

        [Test]
        [TestModule(ModuleAttribute.ModuleName)]
        public void MethodName()
        {
            var httpContext = MockHttphelpers.MockHttpContextBaseWithUrlReferrer("~/pagename", "https://test.abc.com");

            var checkSecureConn = httpContext.Request.IsSecureConnection;
            var userCookie = new HttpCookie("TrackReferrer");
            userCookie.Value = "http://www.google.com,http://test.abc.com";
            userCookie.Secure = true;
            userCookie.HttpOnly = true;
            httpContext.Request.Cookies.Add(userCookie);
            this.TrackingInfo.GetCustomerOriginReferral();

            Assert.AreEqual(httpContext.Session["sessionname"].ToString(), "www.google.com"); 
        }

课程库

public void GetReferral()
        {
            string urlReferrer = HttpContext.Current.Request.UrlReferrer == null ? string.Empty : HttpContext.Current.Request.UrlReferrer.ToString().ToLower();
            if (!string.IsNullOrEmpty(urlReferrer) && new Uri(urlReferrer).Host != HttpContext.Current.Request.Url.Host && HttpContext.Current.Request.Cookies["TrackReferrer"] != null && !string.IsNullOrEmpty(HttpContext.Current.Request.Cookies["TrackReferrer"].Value))
            {
                //Code
            }
        }

HttpContext Mock

public static HttpContextBase MockHttpContextBase()
        {
            var httpContextBase = Substitute.For<HttpContextBase>();

            var httpRequestBase = Substitute.For<HttpRequestBase>();
            var httpResponseBase = Substitute.For<HttpResponseBase>();
            var httpSessionStateBase = Substitute.For<HttpSessionStateBase>();
            var httpServerUtilityBase = Substitute.For<HttpServerUtilityBase>();

            httpRequestBase.Cookies.Returns(new HttpCookieCollection());
            httpResponseBase.Cookies.Returns(new HttpCookieCollection());
            httpRequestBase.ServerVariables.Returns(MockRequestObjects.ServerVariables);
            httpContextBase.Request.Returns(httpRequestBase);
            httpContextBase.Response.Returns(httpResponseBase);
            httpContextBase.Session.Returns(httpSessionStateBase);
            httpContextBase.Server.Returns(httpServerUtilityBase);

            // Initializing HttpContext.Current
            HttpContext.Current = MockHttpContext(); 
            HttpContext.Current.Request.Browser = new HttpBrowserCapabilities() { Capabilities = new Dictionary<string, string> { { "supportsEmptyStringInCookieValue", "false" } } };

            // Initializing Session in HttpContextBase in ControllerContext
            httpContextBase.Session.Returns(MockHttpContextControllerContextSession());

            // Initializing ApplicationInstance in HttpContextBase in ControllerContext
            httpContextBase.ApplicationInstance = new HttpApplication();

            // Initializing ApplicationInstance in HttpContext.Current
            HttpContext.Current.ApplicationInstance = new HttpApplication();
            httpContextBase.Request.ServerVariables.Returns(MockRequestObjects.ServerVariables);

            // Initializing FormCollection in HttpContextBase in ControllerContext
            httpContextBase.Request.Form.Returns(new FormCollection());

            return httpContextBase;
        }
