Rspec控制器错误期望“<" index>>但是使用<> [英] Rspec controller error expecting <"index"> but rendering with <"">

问题描述

以下控制器测试会抛出错误：

  expecting<index>但是使用< 
  

我在我的一个控制器规格中有以下内容：

  require'spec_helper'
 
描述NasController do 
 
 render_views 
 login_user 
 
描述GET #nasdo 
它填充一组设备do 
 @location = FactoryGirl.create（：location）
 @ location.users<<< @current_user 
 @nas = FactoryGirl.create（：nas，location_id：@ location.id）
 get：index 
 assigns（：nas）.should eq（[@ nas]）
 end 
 
它渲染：索引视图do 
 response.should render_template（：index）
 end 
 end 
  

在我的控制器宏中，我有：

  def login_user 
 before（：each）do 
 @ request.env [devise.mapping] = Devise.mappings [：user] 
 @current_user = FactoryGirl.create ：user）
 @ current_user.roles<<< Role.first 
 sign_in @current_user 
 User.current_user = @current_user 
 @user = @current_user 
 @ability = Ability.new（@current_user）
 end 
 end 
  

我正在使用设计和cancan，并遵循他们的指南。测试。我相信我的用户已经登录，并且有能力查看索引操作。

我可以做些什么来让测试通过？

控制器代码：

  class NasController< ApplicationController 
 before_filter：authenticate_user！ 
 load_and_authorize_resource 
 
 respond_to：js 
 
 def index 
 
如果params [：location_id] 
 ... 
 else 
 @nas = Nas.accessible_by（current_ability）.page（params [：page]）。order（sort_column +''+ sort_direction）
 
 respond_to do | format | 
 format.html＃show.html.erb 
 end 
 end 
 end 
  

解决方案

我想如果你改变了

  ：index viewdo 
 response.should render_template（：index）
 end 
  

到

 它呈现：索引视图do 
 get：index 
 response.should render_template （：index）
 end 
  

它应该工作。

更新：尝试这个

 它渲染：索引视图do 
 @location = FactoryGirl.create（：location）
 @ location.users<<< @current_user 
 @nas = FactoryGirl.create（：nas，location_id：@ location.id）
 get：index 
 response.should render_template（：index）
 end 
  

New to testing, I'm struggling to get some controller tests to pass.

The following controller test throws the error:

   expecting <"index"> but rendering with <"">

I have the following in one of my controller specs:

  require 'spec_helper'

  describe NasController do

  render_views
  login_user

  describe "GET #nas" do
      it "populates an array of devices" do
        @location = FactoryGirl.create(:location)
        @location.users << @current_user
        @nas = FactoryGirl.create(:nas, location_id: @location.id )      
        get :index
        assigns(:nas).should eq([@nas])
      end

      it "renders the :index view" do
        response.should render_template(:index)
      end
    end

In my controller macros, I have this:

  def login_user
    before(:each) do
      @request.env["devise.mapping"] = Devise.mappings[:user]
      @current_user = FactoryGirl.create(:user)
      @current_user.roles << Role.first
      sign_in @current_user
      User.current_user = @current_user
      @user = @current_user
      @ability = Ability.new(@current_user)
    end
  end

I'm using devise and cancan and have followed their guides re. testing. I believe my users are signed in before and have the ability to view the index action.

What can I do to get the tests to pass?

-- UPDATE 1 --

Controller code:

class NasController < ApplicationController
   before_filter :authenticate_user!
   load_and_authorize_resource

   respond_to :js

   def index

     if params[:location_id]
       ...
     else
     @nas = Nas.accessible_by(current_ability).page(params[:page]).order(sort_column + ' ' + sort_direction)

     respond_to do |format|
      format.html # show.html.erb
     end    
    end
  end

解决方案

I think if you change

it "renders the :index view" do
  response.should render_template(:index)
end

to

it "renders the :index view" do
  get :index
  response.should render_template(:index)
end

it should work.

update: try this

it "renders the :index view" do
  @location = FactoryGirl.create(:location)
  @location.users << @current_user
  @nas = FactoryGirl.create(:nas, location_id: @location.id ) 
  get :index
  response.should render_template(:index)
end
