[Test]
public void ValidRegistrationDataSuccessfullyCreatesAndRegistersUser()
{
    var context = new Mock<HttpContextBase>() {DefaultValue = DefaultValue.Mock};
    context.SetupAllProperties();
    var provider = new Mock<MembershipProvider>(new object[] {context.Object});
    var controller = new AccountController(context.Object,provider.Object);
    // This just sets up a local FormCollection object with valid user data 
    // in it to use to attempt the registration
    InitializeValidFormData();
    ActionResult result = controller.Register(_registrationData);
    Assert.IsInstanceOfType(typeof(ViewResult),result);
    // Here is where I'd like to attempt to do Assertions against properties 
    // of the HttpContext,like ensuring that a Session object called "User" 
    // exists,and new auth cookie exists on the Response.Cookies collection. 
    // So far I've been unable to successfully check the values of those properties.
    // I've been unsuccessful in getting those properties setup correctly on my 
    // mock object so that my ControllerAction can actually *set* their values,// and that I can make assertions on them afterwards. The above code actually
    // generates a StackOverflowException (which I've reported) on the
    // context.SetupAllProperties() call. What am I doing wrong,or what do I need 
    // to do to be able to set and assert on those context properties?
}

不知道我在做错了什么，但是如果有人能指出正确的方向，我会很喜欢它，并告诉我如何设置这个模拟HttpContextBase对象，使得我的控制器实际上可以在其属性上设置值，我可以断言这些属性，以确保我的ControllerAction正在做我需要的。

我接近这个错误的方式吗？我知道MVC控制器有一个ControllerContext，可以用来为Session等设置值，但是我无法确定如何在没有注入的情况下嘲笑它。有办法吗？ (我也需要能够将上下文传递给我的MembershipProvider)这会是一个更好的方法吗？

谢谢。
