title: How to mock and stub active record before_create callback with factory_girl
body: <p>I have an ActiveRecord Model, PricePackage. That has a before_create call back. This call back uses a 3rd party API to make a remote connection. I am using factory girl and would like to stub out this api so that when new factories are built during testing the remote calls are not made. </p>
  
  <p>I am using Rspec for mocks and stubs. The problem i'm having is that the Rspec methods are not available within my factories.rb</p>
  
  <p>model:</p>
  
  <pre><code>class PricePackage &lt; ActiveRecord::Base
      has_many :users
      before_create :register_with_3rdparty
  
      attr_accessible :price, :price_in_dollars, :price_in_cents, :title
  
  
      def register_with_3rdparty
        return true if self.price.nil?
  
          begin
            3rdPartyClass::Plan.create(
              :amount =&gt; self.price_in_cents,
              :interval =&gt; 'month',
              :name =&gt; "#{::Rails.env} Item #{self.title}",
              :currency =&gt; 'usd',
              :id =&gt; self.title)
          rescue Exception =&gt; ex
            puts "stripe exception #{self.title} #{ex}, using existing price"
            plan = 3rdPartyClass::Plan.retrieve(self.title)
            self.price_in_cents = plan.amount
            return true
          end
      end
  </code></pre>
  
  <p>factory:</p>
  
  <pre><code>#PricePackage
  Factory.define :price_package do |f|
    f.title "test_package"
    f.price_in_cents "500"
    f.max_domains "20"
    f.max_users "4"
    f.max_apps "10"
    f.after_build do |pp|
      #
      #heres where would like to mock out the 3rd party response
      #
      3rd_party = mock()
      3rd_party.stub!(:amount).price_in_cents
      3rdPartyClass::Plan.stub!(:create).and_return(3rd_party)
    end
  end
  </code></pre>
  
  <p>I'm not sure how to get the rspec mock and stub helpers loaded into my factories.rb and this might not be the best way to handle this.</p>
