Binarylogic Authlogic

Here's the top of my test_helper.rb:

ENV["RAILS_ENV"] = "test"
require File.expand_path(File.dirname(__FILE__) + "/../config/environment")
require "authlogic/test_case" # include at the top of test_helper.rb
require 'test_help'

class ActiveSupport::TestCase
  include Authlogic::TestCase
  setup :activate_authlogic # run before tests are executed
  ...
end

And an exemplar test that's failing:

require 'test_helper'

class CheckoutControllerTest < ActionController::TestCase
  setup :set_cart
  
  test "index redirects to gather info" do
    get :index
    assert_redirected_to checkout_info_path
  end

  protected
        
    def set_cart
      session[:cart_id] = carts(:checkout).id
    end
  
end

And I get:

 6) Error:
test_submit_on_review_page_submits_order(CheckoutControllerTest):
NoMethodError: undefined method `controller_path' for Authlogic::TestCase::MockController:Class
    /test/functional/checkout_controller_test.rb:53:in `test_submit_on_review_page_submits_order'

With a fuller backtrace being:

I feel like I'm doing something wrong, but as far as I can tell I match the documentation.

Any suggestions are welcome.
