How to get, mockable, currently logged in username for asp .net membership?

Question

Currently I am using Membership.GetUser() to get the currently logged in username. However this is a static method which is not Mockable. Is there any other way to get the currently logged in username that is mock friendly?

FYI: I am using Moq framework and NUnit.

Answer 1

Generally, in cases like this, you can create a wrapper interface which you can use to stub the GetUser() method.

public interface IMembersipService {
    MembershipUser GetUser();
}

public class MembersipService : IMembersipService
{
    public MembershipUser GetUser() {
        return Membership.GetUser();
    }
}

IMembersipService.GetUser() can be stub/mock based on your need.

Additional note: there are other routines in the Membership class, which you may required to access. You can use the same interface to access wrap those methods. Having a wrapped interface like this around static members provide the testability.

Answer 2

In ASP.NET MVC, HttpContextBase is designed to be mockable, so you can use its User property to get the current logged in user.

Answer 3

This will get you the logged in Username :

string userName = User.Identity.Name;
