我就简单的写了个 Request specs 测试 ---widgets_controller.rb

describe "Widget other  management" do
    it "create a Widget an redirects to the Widget's page " do
      get "widgets/"
      expect(response).to render_template(:index)

      get "widgets/1/edit"
      expect(response).to render_template(:edit)

      get "widgets/1"
      expect(response).to render_template(:update)

      post "widgets/1", widget: {:name => "My Widget"}
      follow_redirect!

      expect(response).to render_template(:show)
      expect(response.body).to include("Widget was successfully updated.")

    end
  end

get "widgets/"肯定是没有问题的

但是我想测试 edit,update，destory ,我该怎么写？get "widgets/1/edit"提示没有 id=1，其实我想写成 get"widgets/id/edit"

======================= 怎么没人回答了，这个是不属于功能测试，应该用 capybara？
