[Newbies] How do I test and share code?

Folks,

I've written a couple of classes that add web-based user management to Pier. The classes let you add new users, remove users, set user's passwords, bless users as superusers, etc.

First, I'd like to write some tests for the classes. Ideally, I'd like to similar HTTP requests on Pier (much like I can do when I write Rails tests) such that I'm testing the functionality of the method in the context of living inside Pier/Seaside.

Second, how do I publish the code? Is it as simple as following the Montecello example video (I added 1 method to a Pier class and put it in the category *pier-security-manager)? Or is there more magic I have to do?

Thanks,

David
