Testing controller Action that uses User.Identity.Name

Question

I have an action that relies on User.Identity.Name to get the username of the current user to get a list of his orders:

public ActionResult XLineas()
    {
          


        

Answer 1

A better way of doing this would be to pass a string argument userName (or an IPrincipal argument user, if you need more information than just the name) to the ActionMethod, which you "inject" in a normal request using an ActionFilterAttribute. When you test it, you just supply your own mock object, as the action filter's code will not run (in most cases - there are ways to, if you specifically want to...)

Kazi Manzur Rashid describes this in detail under point 7 in an excellent blog post.

Answer 2

You can use this code

public SomeController CreateControllerForUser(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 mocking framework, but sure you can use anything you like.
