How do you stub out User.Identity.Name in ASP.NET MVC?

Question

I'm trying to unit test a page in my ASP.NET MVC application that, when posted to, will delete a user's item. I want to restrict this page so that it can only be posted to by the owner of said item. Originally, I wanted to just stick a quick check in the controller that checked if the HttpContext.Current.User.Identity.Name is equal to the owner of the item, but I quickly realized that unit testing this would be difficult.

Should I create an interface that provides a way to access the current logged-in user's name?

You can use this code

Controller CreateControllerAs(string userName) {

  var mock = new Mock<ControllerContext>();
  mock.SetupGet(p => p.HttpContext.User.Identity.Name).Returns(userName);
  mock.SetupGet(p => p.HttpContext.Request.IsAuthenticated).Returns(true);

  var controller = new SomeController();
  controller.ControllerContext = mock.Object;

  return controller;
}

It uses moq lib
