Grails Unit Test "CreateAlias" doesn´t work

I am trying to make a unit test over a namedquery method and it´s not working as I am using the method grails.orm.HibernateCriteriaBuilder.createAlias which doesn´t seem to be found by Grails: " No signature of method: grails.gorm.CriteriaBuilder.createAlias()"

I guess the problem is that when making a unit test and mocking the class, it´s trying to find the method around "grails.gorm.CriteriaBuilder" class and not grails.orm.HibernateCriteriaBuilder class, why ?? any ideas to solve it?

class Book{
  static namedQueries = {     
      testMethod()
      {
         createAlias('name', 'james')
      }
   }
}



@Mock([Book])
class BookTests{
  @Test
  void myTest() {
      Book.testMethod();
   }
}

Error : No signature of method: grails.gorm.CriteriaBuilder.createAlias()
