Test helper classes

Chapter 4 Generating Hibernate Persistent Objects and JSF Pages

Test helper classes provide some utility functions for unit test classes.

A test helper class contains:

a method to create new instance.
a method to modify the instance to be used in update test.
an instance save method. Instances of some classes should be saved first to fulfill foreign key constraints.
an instance delete method. If cascade type properties on both sides of the association are all set to save-update, instances reference should be removed from the class of the other side before deleting them by Hibernate.
a get instance by primary key method.
