in reply to How to apply patches to PM code

Excellent documentation. What I'd really like to see is
"How to test patches (a guide for pmdevils)"

The only patches I've submitted are tiny one or two line changes, since I don't feel comfortable slinging more code than that around w/o a reasonable way to test it. Is there any way to test a patch other than installing a local copy of Everything2, or is the patching process mostly like coding in the dark?

who should probably know better by now....
