title: Grails: Mocking of hibernate domain actions - beforeInsert
body: <p>given a domain constellation like this: </p>
  
  <pre><code>abstract class A { 
      def myService 
      def beforeInsert() { 
          myService.doIt() 
      } 
  } 
  
  class B extends A { 
      def beforeInsert() { 
          super.beforeInsert() 
      } 
  }
  </code></pre>
  
  <p>Is it possible to mock the following methods:
  - beforeInsert() in B?
  - beforeInsert() in A?</p>
