I am trying to come up with a way to build a framework that will let developers code and unit test their yet-to-be-written modules to extend the web application without having to use the actual API code (except for integration testing) and without apache/mod_perl.

That sounds like you want mocks/fakes/stubs here. Take a look at some of the Test Double patterns.

I'm having a hard time trying to figure out is at a high level, how to structure this test framework in such a way that there's not a bunch of code duplication.

Can you give examples of the kind of duplication that you're getting? What's stopping you factoring it out?
