Upgrading application to Ruby 1.8.7, Rails 3 and getting undefined method `config_accessor' for SiteSweeper:Class

Question

I'm struggling through upgrading an app to Rails 3 (Ruby 1.8.7), and my current roadblock is when running 'rake test --trace' i get the following:

** Invoke test (first_time)
** Execute test
** Invoke test:units (first_time)
** Invoke test:prepare (first_time)
** Invoke db:test:prepare (first_time)
** Invoke db:abort_if_pending_migrations (first_time)
** Invoke environment (first_time)
** Execute environment
** Execute db:abort_if_pending_migrations
** Invoke test:functionals (first_time)
** Invoke test:prepare
** Execute test:functionals

The error here points to code that is actually inside the Rails 3.0.11 gem (action_controller/caching/pages.rb:47) and i can't figure out why that would cause problems or why i can't find any others having this problem. I'm also looking for the docs for ActionController::Caching to see if 'config_accessor' would have gone away..?

Any assistance is much appreciated.

I'm not sure that this is a complete answer, but for the applications i'm upgrading the 'test/mocks' directory had nothing in it. Removing the directory removed the deprecation messages.
