ruby-on-rails – 如何在Rails 3插件中测试路由？

奇怪的是,如果我在创建路线后重新加载路线(或者我认为),测试失败,但如果我让测试通过一次(例如使用自动测试),那么路线会在后续尝试中被识别.

这是代码：

describe "named route report_with_last_name_smith_path" do
  before :all do
    Reports::Application.routes.draw do
        match "/report_some_report_for_us" => "report#report_some_report_for_us",:as => :report_some_report_for_us
    end
    Rails.application.reload_routes! # If I leave this out,then the test
                                     # passes the second time that autotest/autospec
                                     # go through.
  end
  it "route for every record" do
    {:get => '/report_some_report_for_us'}.should route_to(:controller => 'report',:action => 'report_some_report_for_us')
  end
end

知道如何让它一直通过吗？
