Yes.  Daniel and I discussed this and he thought listing all test
cases, even the slow ones, would not be an issue, since QA should
be running the default set not the full list
(and for that matter, shouldn't QA know what they are doing too? :P).

Shouldn't 100% useless and superfluous tests be excised completely?

Which is the default behaviour, AFAICT.

Thanks for the suggestion.  Will modify the code accordingly.
That change does indeed simplify things quite a bit!

Kind regards, David
