in reply to using Test::* modules for generic testing of non perl stuff?

I've used Test::Cmdline to test a C program. Apache::Test is excellent to test pretty much any Apache usage. Test::More + LWP will test anything you can talk to over the internet.

Is that what you're asking about?

Being right, does not endow the right to be rude; politeness costs nothing.
Being unknowing, is not the same as being stupid.
Expressing a contrary opinion, whether to the individual or the group, is more often a sign of deeper thought than of cantankerous belligerence.
Do not mistake your goals as the only goals; your opinion as the only opinion; your confidence as correctness. Saying you know better is not the same as explaining you know better.
