rspec测试我的控制器返回nil（+工厂女孩） [英] rspec test of my controller returns nil (+factory girl)

问题描述

我的用户控制器看起来像这样：

我使用Rspec和工厂女孩在Rails学习测试，我不能设法使它们工作。 >

  class UsersController< ApplicationController 
 def index 
 @users = User.all.order（：first_name）
 end 
 end 
  

和测试：

  require'spec_helper'
 
 describe UsersController do 
 
 before（：each）do 
 @ user1 = FactoryGirl.create（：user，first_name：B，last_name：B，uid：b ）
 @ user2 = FactoryGirl.create（：user，first_name：A，last_name：A，uid：a）
 end 
 
 describeGET index do 
 it设置按名字排序的用户列表do 
 get：index 
 assigns（：users）.should == [@ user2，@ user1] 
 end 
 end 
 end 
  

但测试会返回以下结果：

UsersController GET索引设置按名字排序的用户列表
失败/错误：assigns（：users）.should == [@ user2，@ user1]
expected：[＃< User id：nil，email：nil，first_name：A，last_name：A，uid：a，active：true，admin： false，created_at：nil，updated_at：nil，reset_date：nil>，＃< User id：nil，email：nil，first_name：B，last_name：B，uid：b，active：true，admin ：false，created_at：nil，updated_at：nil，reset_date：nil>]
got：nil（using ==）
＃./spec/controllers/users_controller_spec.rb:13:in` level）in< top（required）>'


你有什么想法错误？

干杯！

这里是'rake routes'：

 前缀动词URI模式控制器＃动作
 root GET / meetings＃index 
 meeting GET /meetings(.:format）meetings＃index 
 login GET /login(.:format）sessions＃new 
 logout GET /logout(.format）sessions＃destroy 
 POST /auth/:provider/callback(.:format）sessions＃ create 
 auth_failure GET /auth/failure(.:format）sessions＃failure 
 users GET /users(.:format）users＃index 
 POST /users(.:format）users＃create 
 new_user GET /users/new(.:format）users＃new 
 edit_user GET /users/:id/edit(.:format）users＃edit 
 user GET / users /：id （。：format）users＃show 
 PATCH /users/:id(.:format）users＃update 
 PUT /users/:id(.:format）users＃update 
 DELETE / users /：id（。：format）users＃destroy 
  

解决方案

正如Jvnill上面说的，使用create。另一个选项是在声明它们之后使用@ user1.save。

同样对于路由，在路由文件中检查你的资源。

I am learning tests with rspec and factory girl on Rails and I can't manage to make them work.

My User controller looks like this :

class UsersController < ApplicationController
  def index
    @users = User.all.order(:first_name)
  end
end

and the tests :

require 'spec_helper'

describe UsersController do

before(:each) do
    @user1 = FactoryGirl.create(:user, first_name: "B", last_name: "B", uid: "b")
    @user2 = FactoryGirl.create(:user, first_name: "A", last_name: "A", uid: "a")
end

describe "GET index" do     
    it "sets a list of users sorted by first name" do
        get :index
        assigns(:users).should == [@user2, @user1]
    end
end
end

But the tests returns the following :

UsersController GET index sets a list of users sorted by first name
Failure/Error: assigns(:users).should == [@user2, @user1]
expected: [#<User id: nil, email: nil, first_name: "A", last_name: "A", uid: "a", active: true, admin: false, created_at: nil, updated_at: nil, reset_date: nil>, #<User id: nil, email: nil, first_name: "B", last_name: "B", uid: "b", active: true, admin: false, created_at: nil, updated_at: nil, reset_date: nil>]
got: nil (using ==)
# ./spec/controllers/users_controller_spec.rb:13:in `block (3 levels) in <top (required)>'

Do you have any idea what I am doing wrong ?

Cheers!

Here is the 'rake routes' :

      Prefix Verb   URI Pattern                        Controller#Action
        root GET    /                                  meetings#index
    meetings GET    /meetings(.:format)                meetings#index
       login GET    /login(.:format)                   sessions#new
      logout GET    /logout(.:format)                  sessions#destroy
             POST   /auth/:provider/callback(.:format) sessions#create
auth_failure GET    /auth/failure(.:format)            sessions#failure
       users GET    /users(.:format)                   users#index
             POST   /users(.:format)                   users#create
    new_user GET    /users/new(.:format)               users#new
   edit_user GET    /users/:id/edit(.:format)          users#edit
        user GET    /users/:id(.:format)               users#show
             PATCH  /users/:id(.:format)               users#update
             PUT    /users/:id(.:format)               users#update
             DELETE /users/:id(.:format)               users#destroy

解决方案

As Jvnill said above, use create. The other option is to use @user1.save after declaring them.

Also as far as routes go, check your resources in the routes file.
