Can I pass a set to a test case in DUnitX?

I'm trying to check the state of an object after running a test. This state is contained in a set. Is it possible to pass the expected state to the test case using DUnitX Attributes, so that I can use the same test for all different inputs?

I tried to pass the set as a constant or as a set, but in my Test routine it always arrives as an empty set.

• Is this possible at all using attributes?
• How would you test if sets are identical?

Example code:

type
  TResult = (resOK,resWarn,resError);
  TResultSet = set of TResult;

const
  cErrWarn : TResultSet = [resWarn];

type
  [TestFixture]
  TMyTest = class(TBaseTest)
    [Test]
    [TestCase('Demo1','InputA,[resWarn]')] // <-- tried as a set
    [TestCase('Demo2','InputB,cErrWarn')]  // <-- tried as a constant

    procedure Test(Input:string; ExpectedResult: TResultSet);
  end;

procedure TMyTest.Test(Input:string; ExpectedResult: TResultSet);
begin
  // ExpectedResult is always the empty set []
  RunTests(MyObject(Input));
  Assert.AreEqual(ExpectedResult, MyObject.ResultSet);
end;

Help is greatly appreciated. :)
