Rspec 配置

RSpec.configure do |config|
  config.include Devise::TestHelpers, :type => :controller
  ...

先上路由

devise_for :users, controllers: { passwords: "users/passwords", sessions: "users/sessions", registrations: "users/registrations"}

先说 SessionsController，做了本地化

class Users::SessionsController < Devise::SessionsController    
end

测试代码

require 'spec_helper'

describe Users::SessionsController do

  controller do
    def after_sign_in_path_for(resource)
      super resource
    end
  end

  describe "After user sigin-in" do
    before(:each) do
      @user = FactoryGirl.create(:user)     
    end

    it "change current_user" do
      sign_in @user
      expect( subject.current_user ).to eq(@user)
    end

    it "redirects to the user_root_path" do
      user = FactoryGirl.create(:user)
      controller.after_sign_in_path_for(@user).should == root_path
    end
  end

这个测试没有问题顺利通过！ 然后我依葫芦画瓢来做注册测试，也就是 RegistrationsController 的测试，同样的做了本地化，然后测试代码如下

require 'spec_helper'

describe Users::RegistrationsController do

  # before(:each) do
  #   @request.env["devise.mapping"] = Devise.mappings[:user]
  # end

  controller do
    def after_sign_up_path_for(resource)
      super resource
    end
  end

  describe "User sign_up" do  

    it "change current_user" do
      post :create, user: FactoryGirl.attributes_for(:register_user)
      expect( subject.current_user ).not_to be nil
    end

但是这个测试就没法通过，报错如下

1) Users::RegistrationsController User sign_up change current_user
     Failure/Error: post :create, user: FactoryGirl.attributes_for(:register_user)
     AbstractController::ActionNotFound:
       The action 'create' could not be found for AnonymousController
     # ./spec/controllers/registrations_controller_spec.rb:18:in `block (3 levels) in <top (required)>'

各位有什么建议？
