Im getting the errors below despite following the documentation.

In test_helper.rb

ENV["RAILS_ENV"] = "test"
require File.expand_path(File.dirname(__FILE__) + "/../config/environment")
require "authlogic/test_case"
require 'test_help'
require 'shoulda'
require File.dirname(__FILE__) + "/factories"

In my functional test require 'test_helper'

class SentencesControllerTest < ActionController::TestCase
  setup do
    :activate_authlogic
  end

  context "logged in" do
    setup do
      @user = Factory(:user)
      UserSession.create(@user.id)
    end

    context "on GET to :new" do
      setup do
        get :new
      end

      should "present form with text field" do
        assert_select('form#new_sentence') do
          assert_select('textarea#sentence_text')
        end
      end
    end
  end #context logged in.
end

in environments.rb

  config.gem "authlogic"

Im not sure why it isnt working. Can anyone help out on this?
