deviseを使用したRSpecによるテストモデル

Question

私はrailsアプリケーションでの認証にdeviseを使用しており、RSpecでモデルをテストすることはできません。コントローラ仕様はうまくいきますが、モデル仕様を動作させることができません。私は私のspec_helper.rbで

config.include Devise::TestHelpers 

が含まれている

私はこのエラーを取得しています。 は、ここに私のモデルテストファイル

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 

これは私のfactories.rbファイルが

Factory.define :group do |group| 
    group.name "Example group" 
    group.description "Example description" 
end 

どのようにこの問題を解決するためにされているのですか？
