Rails 3 and AuthLogic NameError: undefined local variable or method `activate_authlogic’ for

This post is a reminder to myself mostly. If you’re getting the following error when using Ruby on Rails 3 with AuthLogic:

NameError: undefined local variable or method `activate_authlogic' for

Then you need to edit your test_helper.rb to include AuthLogic:

require 'authlogic/test_case'
class ActiveSupport::TestCase
  # ...
  include Authlogic::TestCase
  # ...
end
