My question was poorly made. There is an abundance of test programs and I am interested in the broad group of TAP emitting Perl testing programs. While I think most of the significant/popular modules follow Test::More's behaviour, I have no sound basis to support the thought. That thought is what I'd like to confirm or debunk before starting a project.
(Update: "No sound basis"--like I don't even know which see much use.)
I enjoyed your book with Langworth. I didn't care for the antiquing but you two delivered the high quality it was meant to suggest.
