我关注此post关于在我的Rails 4应用程序的路由中设置身份验证。
这是我的routes.rb文件：
Rails.application.routes.draw do
devise_for :employees, :controllers => { registrations: 'employees/registrations' }
devise_for :clients
authenticate :employee do
resources :quotation_requests, only: [:show, :edit,:index, :update, :destroy]
end
resources :quotation_requests, only: [:new, :create]
get '/dashboard' => 'dashboard#show', as: 'show_dashboard'
root to: 'home#index'
end
这是我的quotation_requests_controller_spec.rb文件：
require 'rails_helper'
RSpec.describe QuotationRequestsController, type: :controller do
describe "GET index" do
it "renders :index template" do
get :index
expect(response).to render_template(:index)
end

quotation_requests = FactoryGirl.create_list(:quotation_request, 3)
get :index
expect(assigns(:quotation_requests)).to match_array(quotation_requests)
end
end

let(:quotation_request) { FactoryGirl.create(:quotation_request)}

end

end
it "assigns requested quotation_request to @quotation_request" do

end
end
end

expect(response).to render_template(:new)
end
it "doesn't creates new quotation_request in database" do

end
end
describe "DELETE destroy" do

end
it "delets the quotation request from the database" do

expect(QuotationRequest.exists?(quotation_request.id)).to be_falsy
end
end
end
我的quotation_requests_controller.rb
class QuotationRequestsController < ApplicationController
# before_action :authenticate_employee!, :only => [:show]
def index
@quotation_requests = QuotationRequest.all
end
def new
@quotation_request = QuotationRequest.new
@quotation_request.build_client
end
def edit
@quotation_request = QuotationRequest.find(params[:id])
end
def create
client = Client.find_or_create(quotation_request_params[:client_attributes])
@quotation_request = QuotationRequest.new(quotation_request_params.except(:client_attributes).merge(client: client))
if @quotation_request.save
ClientMailer.quotation_request_created(client.email, @quotation_request.id).deliver_now
redirect_to @quotation_request, notice: 'Thank you.'
else
render :new
end
end
def show
@quotation_request = QuotationRequest.find(params[:id])
end
def update
@quotation_request = QuotationRequest.find(params[:id])
if @quotation_request.update(quotation_request_params)
redirect_to @quotation_request
else
render :edit
end
end
def destroy
QuotationRequest.destroy(params[:id])
redirect_to quotation_requests_path
end
private
def quotation_request_params
params.require(:quotation_request).permit(:number_of_words, :return_date, :sample_text, :client_attributes => [:first_name, :last_name, :email])
end
end
我知道路由验证有效，因为如果我在浏览器中测试它，我会被重定向到sign_in页面。但是，测试不会通过Rspec。
如果我将此代码放在quotation_requests_controller.rb中：
before_action :authenticate_employee!, :only => [:show]
rspec测试通过。因此，由于某种原因，Rspec没有注册路由的身份验证。
以下是使用经过身份验证的路径运行的测试的Rspec输出：

为什么我写的路线在Rspec测试中不起作用？
答案 0 :(得分：2)
我认为你在rails应用中使用rspec-rails。 Rspec-rails为你设置了很多方便的方法，但它也引入了一些黑魔法，这可能导致一些意想不到的结果 - 就像这样。
As you can see here在控制器规范的注释中对此进行了解释：
# Supports a simple DSL for specifying behavior of ApplicationController.
# Creates an anonymous subclass of ApplicationController and evals the
# `body` in that context. Also sets up implicit routes for this
# controller, that are separate from those defined in "config/routes.rb".
我想这里的逻辑是，控制器功能与路由不同，应该单独测试（事实上rspec-rails提供了一个路由测试组），所以我们不需要控制器规范的路由，这意味着你应该是能够在不设置路线的情况下测试控制器。
在我的观点中，测试未经身份验证的用户的重定向更多是集成测试，因为它需要应用程序的多个部分协同工作，因此不应在控制器上下文中进行测试，而应在某些部分中进行测试黑盒测试。
您可以通过将集成测试放在其中一个目录spec/requests, spec/api, and spec/integration中或通过明确声明其类型来编写集成测试
RSpec.describe "Something", type: :request do
或将其放在spec/features中或将类型声明为
RSpec.describe "Something", type: :feature do
取决于您要测试重定向的级别（意味着：仅测试请求 - 响应周期，或在模拟的浏览器中运行）。 有关详细信息，请参阅rspec-rails github page上的集成测试文档。
