Question

过去几天我一直在进行我的测试，并且通过帮助测试遇到了麻烦。我收到以下错误：

ActionController::UrlGenerationError: No route matches {:action=>"index", :direction=>"asc", :sort=>"publish_date"}
    app/helpers/main_pages_helper.rb:14:in `sortable'
    test/helpers/main_pages_helper_test.rb:24:in `block in <class:MainPagesHelperTest>'

帮助程序基于#228 railscast，主要是main_pages_helper.rb代码：

module MainPagesHelper

  def sortable(column, title = nil)
        direction = (column == params[:sort] && params[:direction] == "asc") ? 
            "desc" : "asc"

            # check if sort parameter is being used
            if params[:sort] == column
                title += direction == "asc" ? " ▾" : " ▴"
            end

            link_to title, :sort => column, :direction => direction
  end

        # Not yet tested
        def categorizable(category)

            category_select = params[:cat_sort] == category ? 
            params[:cat_sort] = nil : category

            link_to category, :cat_sort => category_select, 
            :sort => params[:sort], :direction => params[:direction]
        end
end

这是main_pages_helper_test.rb代码：

require 'test_helper'

class MainPagesHelperTest < ActionView::TestCase
include MainPagesHelper

    test "should sort time descending" do
      assert_equal(sortable("publish_date", "proj_list"), 
                  (link_to "proj_list", :sort => "publish_date",
                   :direction => "desc"))
    end 

end

我不应该使用assert_equal作为测试方法吗？我是否应该使用ActionView :: TestCase来测试助手？

在rails helper方法中测试link_to输出
