测试模型与RSpec使用设计 [英] Testing models with RSpec using devise

问题描述

我在rails应用程序中使用devise进行身份验证，我无法使用RSpec测试任何型号。控制器规格工作正常，但我无法使模型规格正常工作。

我收到此错误：

 失败：
 
 1）组应该创建新组
 
失败/错误：无法从backtrace找到匹配行
 NoMethodError：

我已经包括
  config.include Devise ::我的spec_helper.rb中的TestHelpers 
  
 
这是我的模型测试文件
  require'spec_helper'
 
 describe Group do 
 
 before：each do 
 @group = Factory.build（：group）
 end 
 
它应该创建新组do 
 Group.create！（@ group）
 end 
 end 
  
这是我的factory.rb文件
  Factory.define：group do | group | 
 group.name示例组
 group.description示例描述
 end 
  
如何解决这个问题？
解决方案
 
  config.include设计： ：TestHelpers，：type => ：控制器
  
 
I am using devise for authentication in my rails app and I'm unable to test any model with RSpec. Controller specs work fine, but I'm unable to make model specs work.

I am getting this error:
Failures:

1) Group should create new group

I have included 
  config.include Devise::TestHelpers
in my spec_helper.rb. 
Here is my model test file
require 'spec_helper'

describe Group do

  before :each do 
    @group = Factory.build(:group)
  end 

  it "should create new group" do
    Group.create!(@group)
  end
end
This is my factories.rb file
Factory.define :group do |group|
  group.name "Example group"
  group.description "Example description"
end
How to fix this?
解决方案
config.include Devise::TestHelpers, :type => :controller
