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

Question

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 Attri

Answer 1

Add this conversion function to DUnitX.Utils and put it into the Conversions matrix for tkUString to tkSet (due to limitations of StringToSet and TValue this only works for sets up to 32 elements, for larger sets of up to 256 elements there is more code required though):

function ConvStr2Set(const ASource: TValue; ATarget: PTypeInfo; out AResult: TValue): Boolean;
begin
  TValue.Make(StringToSet(ATarget, ASource.AsString), ATarget, AResult);
  Result := True;
end;

Also you need to use a different separator char for the parameters or it will split them wrong:

[TestCase('Demo1','InputA;[resWarn,resError]', ';')]
