Rails 5 路由规范需要：路径值

Question

将 Rails 4.2.8 升级到 5.0 后，我的所有路由规范都失败并显示相同的错误消息：

1) UsersController routing routes to SHOW
     Failure/Error: expect(get: '/users/joe-smith').to route_to('users#show', id: 'joe-smith')

       The recognized options <{"path"=>"users/joe-smith", "controller"=>"users", "action"=>"show", "id"=>"joe-smith"}> did not match <{"id"=>"joe-smith", "controller"=>"users", "action"=>"show"}>, difference:.

Finished in 0.05154 seconds (files took 6.86 seconds to load)
1 example, 1 failure

Failed examples:

rspec ./spec/routing/users_controller_routing_spec.rb:9 # UsersController routing routes to SHOW

规格：

it 'routes to SHOW' do
  expect(get: '/users/joe-smith').to route_to('users#show', id: 'joe-smith')
end

有人知道为什么会这样吗？我没有在 Rails 5 CHANGELOG 中看到任何内容。

更好的解决方法是开始转向更多future proof method 的测试，以提供更多价值：

require 'rails_helper'
RSpec.describe "Users", type: :request do
  let(:user) { create(:user) }

  describe "GET /users/:id" do
    it "takes a username as the id param" do
       get user_path(user.user_name)
       expect(response).to be_successful
    end
  end
end
