rails 4 - test_helper

we have file: lib/auth_helper.rb which includes some functions. We need to include this lib to our tests.

Rails 3

test/test_helper.rb

class ActiveSupport::TestCase
  include AuthHelper
end

In Rails 4 it doesn't work.

Rails 4

test/test_helper.rb

autoload :AuthHelper, 'auth_helper'

class ActiveSupport::TestCase
  include AuthHelper
end
