Rails - Oct 2006 - Tests for plugins - "require"d files

Hi,

I''m having trouble writing tests for a plugin I''m working on.
In my plugin directory, I have /lib/my_plugin.rb :
 ===== require ''extensions'' # in [plugin]/lib
 
 class NewClass < ActiveForm # ActiveForm defined in a different plugin
 end
 =====
My [plugin]/test/my_test.rb has the following
 ===== require ''test/unit''
 require File.dirname(__FILE__) + ''/../lib/my_plugin''
 =====
However, I get 
 ===== "in `gem_original_require'': no such file to load --
extensions (LoadError)"
 =====
and, if I remove the call to require ''extensions''

 ===== uninitialized constant ActiveForm (NameError)
 =====
How can I write my tests/structure my plugin to avoid these errors?

As an aside, is there any documentation on what the load path is at any given
time? I mean something saying "[these] directories are available when
[...]"
rather than me having to try ''puts''ing a variable at different
points in my
application to learn through trial and error

Thanks,
Gareth

This is the situation:

[plugin]/lib/my_module.rb
=====require ''validations''

module MyModule
  module Transaction
    class Request
# All of these give a NameError
#      include Validations
#      include parent.Validations
#      include MyModule::Transaction::Validations
      [...]
    end
  end
end
=====
[plugin]/lib/validations.rb
=====require ''validations''

module MyModule
  module Transaction
    module Validations
      [...]
    end
  end
end
=====
[plugin]/init.rb
=====require ''validations''
require ''my_module''

# Also gives the same NameError:
#
# VSPDirect::Transaction::Request.module_eval do
#   include Validations
# end
=====
The question is, what is the best way of doing what I''m trying to do? I
hope
it''s obvious, but if it''s not then ask for clarification
