ATM does not work in Rails 2.3 Edge
add to test/spec_helper to make it work again…
#spec_helper / test_helper include ActionController::TestProcess

Moved in Rails 3
In Rails 3, this has moved to ActionDispatch::TestProcess
(Which means, if you want to use it in a test, you need to add the following to test_helper.rb:)
include ActionDispatch::TestProcess

require it
require ‘action_dispatch/testing/test_process’
