How-to test action filters in ASP.NET MVC?

Solution
1) Mocking Request.Url in ActionExecutedContext:
var request = new Mock<HttpRequestBase>();
request.SetupGet(r => r.HttpMethod).Returns("GET");
request.SetupGet(r => r.Url).Returns(new Uri("http://somesite/action"));
var httpContext = new Mock<HttpContextBase>();
httpContext.SetupGet(c => c.Request).Returns(request.Object);
var actionExecutedContext = new Mock<ActionExecutedContext>();
actionExecutedContext.SetupGet(c => c.HttpContext).Returns(httpContext.Object);
2) Suppose you are injecting session wrapper in your RememberUrlAttribute's public constructor.
var rememberUrl = new RememberUrlAttribute(yourSessionWrapper);
rememberUrl.OnActionExecuted(actionExecutedContext.Object);
// Then check what is in your SessionWrapper
Problem
Need some pointers for this. Found this and this, but I'm still kind a confused. I just want to mock ActionExecutedContext, pass it, let filter to work a bit and check result. Any help? Source of filter you can find here (it's changed a bit, but that's not a point at the moment). So - i want unit test, that RememberUrl filter is smart enough to save current URL in session.
