验证用户是否通过操作身份验证

我正在使用device,并希望检查我的规范中是否包含某些控制器操作 authenticate_user!

我看过了设计文档,我觉得有一些非常简单和明显的东西,我不了解设计的工作方式。

基于 this SO post 我建立了一个规范来检查这个,但它似乎不起作用。

运行规范时,我得到:

 Failure/Error: expect(controller).to receive(:authenticate_user!)

   (#<LibrariesController:0x000001035639f8>).authenticate_user!(*(any args))
       expected: 1 time with any arguments
       received: 0 times with any arguments

库控制器规范.rb

require 'rails_helper'

RSpec.describe LibrariesController, type: :controller do

  let(:valid_attributes) {
    skip("Add a hash of attributes valid for your model")
  }

  let(:invalid_attributes) {
    skip("Add a hash of attributes invalid for your model")
  }

  let(:valid_session) { {} }

  describe "GET #index" do
    it "should be authenticated" do
      get :index, {}
      expect(controller).to receive(:authenticate_user!)
    end
  end
end

控制器本身:

库_控制器.rb

class LibrariesController < ApplicationController
  before_action :set_library, only: [:show, :edit, :update, :destroy]
  before_action :authenticate_user!

  # GET /libraries
  # GET /libraries.json
  def index
    @libraries = Library.all
  end

  private
    # Use callbacks to share common setup or constraints between actions.
    def set_library
      @library = Library.find(params[:id])
    end
end
