Ruby on rails Rspec测试中的designe认证

我很难让我的Rspec测试在designe试图在before_过滤器中验证用户的项目上正确运行

我遵循了Desive Git wiki中的示例：

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（直接来自发电机，添加前置过滤器除外：

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

class ProjectsController

为什么在包含

subject.current\u user.should\u not nil

的情况下测试通过了，但在未包含的情况下测试失败了？

我在下面的过程中遇到了同样的问题。解决方法是从每个请求中删除对

有效会话的调用，因为它会覆盖
签名设置的会话值呃

它实际上是在同一个操作指南的代码块中记录的，我也错过了：（
伙计，你应该赢得一枚奖牌！Wiki链接现在是：
