检查Rails 4中不存在路由(Check a route does not exists in Rails 4)

 我停用了用户注册（宝石设计），我想做一个测试，以确保路由/users/sign_up不存在。 
 
 为此，我在spec/features/user_spec.rb创建了一个测试 
 
require 'spec_helper'
require 'capybara/rspec'

feature "Users" do
  scenario "could not register " do
    expect(:get => "/users/sign_up").not_to be_routable
  end
end
 
 当我运行此测试时，我有这个错误： 
 
1) Users could not register
   Failure/Error: expect(:get => "/users/sign_up").not_to be_routable
   NoMethodError:
     undefined method `routable?' for {:get=>"/users/sign_up"}:Hash
   # ./spec/features/user_spec.rb:8:in `block (2 levels) in <top (required)>'

I deactivated the user registration (Gem Devise) and I want to make a test to be sure the route /users/sign_up does not exists.
 
To do this I created a test in spec/features/user_spec.rb
 
require 'spec_helper'
require 'capybara/rspec'

feature "Users" do
  scenario "could not register " do
    expect(:get => "/users/sign_up").not_to be_routable
  end
end
 
When I run this test, I have this error :
 
1) Users could not register
   Failure/Error: expect(:get => "/users/sign_up").not_to be_routable
   NoMethodError:
     undefined method `routable?' for {:get=>"/users/sign_up"}:Hash
   # ./spec/features/user_spec.rb:8:in `block (2 levels) in <top (required)>'
