I'm currently in the process of getting started with unit testing and mocking for good and I stumbled over the following method that I can't seem to fabricate a working mock implementation for:

function GetInstance(const AIID: TGUID; 
                       out AInstance; 
                     const AArgs: array of const; 
                     const AContextID: TImplContextID = CID_DEFAULT): Boolean;

(TImplContextID is just an alias for Integer)

I thought it would have to look something like this:

function TImplementationProviderMock.GetInstance(
  const AIID: TGUID;
    out AInstance;
  const AArgs: array of const;
  const AContextID: TImplContextID): Boolean;
begin
  Result := AddCall('GetInstance')
           .WithParams([@AIID, AContextID])
           .ReturnsOutParams([AInstance])
           .ReturnValue;
end;

But the compiler complains about the .ReturnsOutParams([AInstance]) saying "Bad argument type in variable type array constructor.". Also I haven't found a way to specify the open array parameter AArgs at all.

Also, is using the @-notation for the TGUID-typed parameter the right way to go?

Is it possible to mock this method with the current version of PascalMock at all?
