MSTEST PrincipalPermission

Question

How do you unit test code decorated with the PrincipalPermission attribute?

For example, this works:

class Program
{
    static void Main(string[]          


        

Answer 1

How about creating a GenericIdentity and attaching that to the Thread.CurrentPrincipal in your test like so:

[TestMethod]
public void TestMethod1() 
{ 
    var identity = new GenericIdentity("tester");
    var roles = new[] { @"BUILTIN\Users" };
    var principal = new GenericPrincipal(identity, roles);
    Thread.CurrentPrincipal = principal;

    var c = new MyClass();
}

For a fail test, you could:

[TestMethod]
[ExpectedException(typeof(SecurityException))] // Or whatever it's called in MsTest
public void TestMethod1() 
{ 
    var identity = new GenericIdentity("tester");
    var roles = new[] { @"BUILTIN\NotUsers" };
    var principal = new GenericPrincipal(identity, roles);
    Thread.CurrentPrincipal = principal;

    var c = new MyClass();
}
