If you have lots of Controllers to Test then I Would Suggest to create a base class and in the constructor create a GenericIdentity & GenericPrincipal and set Thread.CurrentPrincipal

GenericPrincipal principal = new GenericPrincipal(new 
    GenericIdentity("UserName"),null); Thread.CurrentPrincipal = principal; 

Then Inherit that class .. So that way every Unit Test class will have Principle Object Set

[TestClass]
public class BaseUnitTest
{
    public BaseUnitTest()
    {
      GenericPrincipal principal = new GenericPrincipal(new GenericIdentity("UserName"),null);   
      Thread.CurrentPrincipal = principal;
    }
}


[TestClass]
public class AdminUnitTest : BaseUnitTest
{
   [TestMethod]
   public void Admin_Application_GetAppliction()
   {
   }
}
