Understood. What led me to contimplating those thoughts was the fact that some tests use hostport, and config, and a custom path, but just don't set A::TR::module. If it weren't for that, those test could be slimmed as well.
That's when they use the default port. But that doesn't sound right, since they shouldn't need hostport/config and stuff. Where do you see such a test?
Now I have to go searching again. :-)
modperl/t/hooks/trans.t - does module2path, config, then hostport. No module, but does custom urls towards the end.
I know there's a couple more lurkers in there, but maybe I'll stumble across those during another round of module2path-ing.
