Thank you !

I think I understand what you mean. But then I slightly disagree : if we want to use such a useful program to randomize tests and a free software doing that does not exist, it is not a reason for a “policy maker” to buy a proprietary software, but a reason to pay a developer to write free code.

But if all you mean is “if you HAVE to buy proprietary software, at least do it for something more useful (like randomizing tests)”, yes of course I agree with that !
