Testing a rest plugin

Hello, I have a plugin that interacts with nearly all parts of rails
(Controller / ActiveRecord / Routing / Views / Views’ Helpers) I’m in
the need of some sort of integration testing.

My idea is to step on the test directory of the plugin and type “rails
app” to make some very simple app to test it.

I would like to know if i’m shooting in my foot somehow by doing this, i
believe that is the way the
http://groups.google.com/group/make_resourceful tests work, but i’m not
quite sure.

An interesting fact is that my plugin “automatically” interacts with
will_paginate plugin and ferret gem, so i need those present when
testing my plugin.

Any sugestions?
