Question

我正在使用MVC5来创建一个基于文化的项目。我正在使用MOQ为我的应用程序创建一些测试用例，但我无法在此找到我的路由。我正在使用一个名为MockHttpContext的类来获取我的httpcontext，如下所示。

public static HttpContextBase MockHttpContext()
{                    
   var context = new Mock<HttpContextBase>();
   var request = new Mock<HttpRequestBase>();
   var response = new Mock<HttpResponseBase>();
   var session = new Mock<HttpSessionStateBase>();
   var server = new Mock<HttpServerUtilityBase>();
   var user = new Mock<IPrincipal>();
   var identity = new Mock<IIdentity>();
   var urlHelper = new Mock<UrlHelper>();

   var routes = new RouteCollection();
   RouteTable.Routes.Clear();
   var areaRegistration = new AdminAreaRegistration();
   var areaRegistrationContext = new AreaRegistrationContext(
   areaRegistration.AreaName, RouteTable.Routes);
   areaRegistration.RegisterArea(areaRegistrationContext);           

   RouteConfig.RegisterRoutes(RouteTable.Routes);
   var requestContext = new Mock<RequestContext>();
   requestContext.Setup(x => x.HttpContext).Returns(context.Object);
   context.Setup(ctx => ctx.Request).Returns(request.Object);
   context.Setup(ctx => ctx.Response).Returns(response.Object);
   context.Setup(ctx => ctx.Session).Returns(session.Object);
   context.Setup(ctx => ctx.Server).Returns(server.Object);
   context.Setup(ctx => ctx.User).Returns(user.Object);
   user.Setup(ctx => ctx.Identity).Returns(identity.Object);
   identity.Setup(id => id.IsAuthenticated).Returns(true);
   identity.Setup(id => id.Name).Returns("test");
   request.Setup(req => req.Url).Returns(new Uri("http://localhost/"));
   request.Setup(req => req.RequestContext).Returns(requestContext.Object);
   requestContext.Setup(x => x.RouteData).Returns(new RouteData());
   request.SetupGet(req => req.Headers).Returns(new NameValueCollection());
   return context.Object;
 }

   //this method is being called in my test class like..

[TestMethod]
public void Index()
{
   try
   {
      var controller = new HomeController();
      var httpContext = MvcMockHelpers.MockHttpContext();
      var routeData = RouteTable.Routes.GetRouteData(httpContext);
      controller.SetMockControllerContext(
      httpContext, routeData, RouteTable.Routes);
      ViewResult result = controller.Index() as ViewResult;

      Assert.AreEqual(result, ErrorResources.Error);

    }
    catch(Exception ex)
    {
      throw ex;
    }
  }

但问题是这样的：每当我试图在我的实用程序中获取我的上下文时使用下面的线来获得文化。

var context = new HttpContextWrapper(System.Web.HttpContext.Current);
var routeData = RouteTable.Routes.GetRouteData(context);           
var code = routeData.Values[Constants.CULTURE];

我得到的上下文返回空路由，意味着Route和RouteHandler为null，键/值也为0，所以我试着检查这一行。

 requestContext.Setup(x => x.RouteData).Returns(new RouteData());

在这一行中，new RouteData()为空，即使我之前已经注册过它。那么在这种情况下如何才能获得RouteData()？

问题是微不足道的，因为你没有使用模拟的HttpContextBase。用以下内容替换第二个代码块。

var context = MockHttpContext();
var routeData = RouteTable.Routes.GetRouteData(context);           
var code = routeData.Values[Constants.CULTURE];

无法在MVC项目中检索RouteData
