The assertDatabaseSchema() method first calls Configuration.generateSchema-
UpdateScript() to generate the script. It then finds any significant differences by
ignoring DDL commands to add constraints. It fails if it encounters any DDL com-
mands that add tables or columns.
HibernatePersistenceTests
In addition to HibernateMappingTests and HibernateSchemaTests , ORMU nit
defines the HibernatePersistenceTests class, which extends JU nit TestCase and
makes it easier to write tests for persistent objects. It defines setUp() and tear-
Down() methods that implement the boilerplate code of a Hibernate persistence
test and provides methods for manipulating persistent data and managing trans-
actions, including:
doInTransaction() : Executes the callback method within a Hibernate trans-
action and ensures that the same Session is used throughout. It does this
using a Spring TransactionTemplate that is configured to use a Hibernate-
TransactionManager .
save() : Saves an object by calling HibernateTemplate.save() .
load() : Loads a persistent object by calling HibernateTemplate.load() .
delete() : Deletes a persistent object by calling HibernateTemplate.delete() .
See this topic's online source code for the details of the class. Let's now look at
some tests that use ORMU nit.
