Using MbUnit with Delphi Prism

Question

I have created below simple testcase in Delphi Prism. When I run the testcase using Gallio Icarus, it returns a This test is not supported by any available test framework.

I can think of only two reasons why this might be happening

• I am missing something (really) obvious. A setting, a missing initialization somewhere, ...
• It is not possible to use the MbUnit - Gallio combination with Delphi Prism.

I do hope it is because I am missing something obvious. In case it isn't, what do other people use as testframework using Delphi Prism?

namespace MailExtensionTests;

interface

uses
  MbUnit.Framework;

type
  Class1 = public class
  public
    [Test]
    procedure TestSomething;
  end;

implementation

procedure Class1.TestSomething;
begin
  Assert.IsTrue(True);
end;

end.
