How do I test helpers in Rails?

Question

I\'m trying to build some unit tests for testing my Rails helpers, but I can never remember how to access them. Annoying. Suggestions?

Stolen from here: http://joakimandersson.se/archives/2006/10/05/test-your-rails-helpers/

require File.dirname(__FILE__) + ‘/../test_helper’
require ‘user_helper’

class UserHelperTest < Test::Unit::TestCase

include UserHelper

def test_a_user_helper_method_here
end

end

[Stolen from Matt Darby, who also wrote in this thread.] You can do the same in RSpec as:

require File.dirname(__FILE__) + '/../spec_helper'

describe FoosHelper do

  it "should do something" do
    helper.some_helper_method.should == @something
  end

end
