My comments here should be taken with a fairly healthy grain of salt, since I am more of a beginning tester than a power tester, and since my experience is mostly limited to Test::More. I definitely don't know all of what is out there.

That said, a module like Test::Cases (Test::Casefiles seems a little clearer to me) would have been useful for me (or might still be) when I was doing a lot of html filtering and parsing. Mainly as a turnkey setup for dealing with all those files. Putting input and output in the same file seems like a pretty clear approach. This might have been the kind of module that I would have been glad to stumble on while wandering CPAN.

So there are my 2cts.

sub jf { print substr($_[0], -1);
               jf( substr($_[0], 0, length($_[0])-1))
                    if length $_[0] > 1; }
jf('gro.alubaf@yehaf');
