今天我們看看怎么測(cè)試我們的helper方法:

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

class HelperTest < Test::Unit::TestCase
  include ActionView::Helpers::UrlHelper
  include ActionView::Helpers::TextHelper
  include ActionView::Helpers::TagHelper
  include ApplicationHelper
  # include whatever helpers you want to test here, sometimes you'll need
  # to include some of the Rails helpers, as I've done above.

  def test_some_helper
  end
end

通過(guò)include ApplicationHelper，則該類里面定義的所有方法都可以作為本地方法得到
如果想測(cè)試其它類里面的helper方法，我們只需要將該類include即可
