在Rspec测试中使用Devise认证 [英] Authentication with Devise in Rspec tests

问题描述

我按照这个例子，从...中获取我的Rspec测试，以便正确运行Devise试图在before_filter中验证用户的项目。 Devise Git wiki：如何：使用Rails 3（和rspec）进行控制器和视图测试

spec / spec_helper.rb：

 ＃此文件复制到spec /当您运行'rails generate rspec：install'
 ENV [RAILS_ENV] || =' test'
 require File.expand_path（../../ config / environment，__FILE__）
 require'rspec / rails'
 require'rspec / autorun'
 
 Dir [Rails.root.join（spec / support / ** / *。rb）]。each {| f | require f} 
 
 RSpec.configure do | config | 
 config.include Devise :: TestHelpers，：type => ：controller 
 config.extend ControllerMacros，：type => ：controller 
 config.fixture_path =＃{Rails.root} / spec / fixtures
 config.use_transactional_fixtures = true 
 config.infer_base_class_for_anonymous_controllers = false 
 end 
  

spec / support / controller_macros.rb：

  module ControllerMacros 
 def login_user 
 before（：each）do 
 @ request.env [devise.mapping] = Devise.mappings [：user] 
 user = FactoryGirl.create（：user）
 sign_in user 
 end 
 end 
 end 
  

spec / controllers / test.rb：

  require'spec_helper'
描述ProjectsController do 
 def valid_attributes 
 {
：name => '项目'，
：description => '描述'
} 
 end 
 
 def valid_session 
 {} 
 end 
 
描述Testdo 
 
 login_user 
 
它将所有项目分配为@projectsdo 
＃test如果以下行在这里，则通过，否则失败
 subject.current_user.should_not be_nil 
 
 project = Project.create！ valid_attributes 
 get：index，{}，valid_session 
 assigns（：projects）.should eq（[project]）
 end 
 end 
 end 
  

app / controllers / projects_controller.rb（直接从生成器除了添加以前的过滤器之外：

 类ProjectsController< ApplicationController 
 
 before_filter：authenticate_user！
 
＃GET / projects 
 ＃GET /projects.json 
 def index 
 @projects = Project.all 
 
 respond_to do | format |

 end 
 end 
 
＃GET / projects / 1 
＃GET /projects/1.json

 @project = Project.find（params [：id]）
 
 respond_to do | format |

 end

 @project = Project.new 
 
 respond_to do | format |

 end 
 end 
 
＃GET / projects / 1 / edit 
 def edit 
 @project = Project.find（params [：id]）
 end 
 
＃POST / projects 
＃POST / project.json 
 def create 
 @project = Project.new（params [：project]）
 
 respond_to do | format | 
 if @ project.save 
 format.html {redirect_to @project，notice：'Project was successfully created。'
 format.json {render json：@project，status：：created，位置：@project} 
 else 
 format.html {render action：new} 
 format.json {render json：@ project.errors，status：：unprocessable_entity} 
 end 
 end 
 end 
 
＃PUT / projects / 1 
＃PUT /projects/1.json 
 def update 
 @project = Project.find（params [：id]）
 
 respond_to do | format | 
 if @ project.update_attributes（params [：project]）
 format.html {redirect_to @project，notice：'Project was successfully updated。'} 
 format.json {head：ok} 
 else 
 format.html {render action：edit} 
 format.json {render json：@ project.errors，status：：unprocessable_entity} 
 end 
 end 
 end 
 
＃DELETE / projects / 1 
＃DELETE /projects/1.json 
 def destroy 
 @project = Project.find（params [：id]）
 @ project.destroy 
 
 respond_to do | format | 
 format.html {redirect_to projects_url} 
 format.json {head：ok} 
 end 
 end 
 end

为什么测试通过包含 subject.current_user.should_not be_nil 但是失败，当它是不包括？
解决方案
在以下您如何提及。解决方案是从每个请求中删除对 valid_session 的调用，因为它会覆盖由 sign_in 设置的会话值，帮助者。
 
 
 
实际上，在一个代码块中记录了相同的方法，我也错过了：（
 
I'm having trouble getting my Rspec tests to run correctly on items where Devise is trying to authenticate a user in a before_filter.

I followed the example from the Devise Git wiki: How To: Controllers and Views tests with Rails 3 (and rspec)

spec/spec_helper.rb:
# This file is copied to spec/ when you run 'rails generate rspec:install'
ENV["RAILS_ENV"] ||= 'test'
require File.expand_path("../../config/environment", __FILE__)
require 'rspec/rails'
require 'rspec/autorun'

Dir[Rails.root.join("spec/support/**/*.rb")].each {|f| require f}

RSpec.configure do |config|
   config.include Devise::TestHelpers, :type => :controller
   config.extend ControllerMacros, :type => :controller
   config.fixture_path = "#{::Rails.root}/spec/fixtures"
   config.use_transactional_fixtures = true
   config.infer_base_class_for_anonymous_controllers = false
end
spec/support/controller_macros.rb:
 module ControllerMacros
   def login_user
     before(:each) do
       @request.env["devise.mapping"] = Devise.mappings[:user]
       user = FactoryGirl.create(:user)
       sign_in user
     end
   end
 end
spec/controllers/test.rb:
require 'spec_helper'
describe ProjectsController do
  def valid_attributes
    {
    :name         => 'Project',
    :description  => 'Description'
    }
  end

  def valid_session
    {}
  end

  describe "Test" do

    login_user

    it "assigns all projects as @projects" do
      # test passes if the following line is here, otherwise fails
      subject.current_user.should_not be_nil

      project = Project.create! valid_attributes
      get :index, {}, valid_session
      assigns(:projects).should eq([project])
    end
  end
end
app/controllers/projects_controller.rb (straight from generator except for addition of a before filter:
class ProjectsController < ApplicationController

  before_filter :authenticate_user!

  # GET /projects
  # GET /projects.json
  def index
    @projects = Project.all

    respond_to do |format|
      format.html # index.html.erb
      format.json { render json: @projects }
    end
  end

  # GET /projects/1
  # GET /projects/1.json
  def show
    @project = Project.find(params[:id])

    respond_to do |format|
      format.html # show.html.erb
      format.json { render json: @project }
    end
  end

  # GET /projects/new
  # GET /projects/new.json
  def new
    @project = Project.new

    respond_to do |format|
      format.html # new.html.erb
      format.json { render json: @project }
    end
  end

  # GET /projects/1/edit
  def edit
    @project = Project.find(params[:id])
  end

  # POST /projects
  # POST /projects.json
  def create
    @project = Project.new(params[:project])

    respond_to do |format|
      if @project.save
        format.html { redirect_to @project, notice: 'Project was successfully created.' }
        format.json { render json: @project, status: :created, location: @project }
      else
        format.html { render action: "new" }
        format.json { render json: @project.errors, status: :unprocessable_entity }
      end
    end
  end

  # PUT /projects/1
  # PUT /projects/1.json
  def update
    @project = Project.find(params[:id])

    respond_to do |format|
      if @project.update_attributes(params[:project])
        format.html { redirect_to @project, notice: 'Project was successfully updated.' }
        format.json { head :ok }
      else
        format.html { render action: "edit" }
        format.json { render json: @project.errors, status: :unprocessable_entity }
      end
    end
  end

  # DELETE /projects/1
  # DELETE /projects/1.json
  def destroy
    @project = Project.find(params[:id])
    @project.destroy

    respond_to do |format|
      format.html { redirect_to projects_url }
      format.json { head :ok }
    end
  end
end
Why does the test pass with the inclusion of subject.current_user.should_not be_nil but fails when it is not included?
解决方案
I ran into the same problem when following the how-to you mention. The solution is to remove calls to valid_session from each of the requests, since it overrides the session values set by the sign_in helper.

It's actually documented in a code-block in the very same how-to, I missed it too :(
