On a technical note, the best solution is to explain you an example. As for
every layer in an application, unit tests are welcome. This is too true for
the entities mapped via JPA. So if you want to test an entity, you will
create an unit test class (for example with JUnit). In this class, you will
add some tests. For example, you will write a test that create an instance
of the entity, set values, persist the entity, retrieve the entity, and
check if the retrieved object is exactly the same as the persisted entity.
It allows you to control that your annotations are matching the definition
of the real table in the database. You can do extra tests: check the
nullable attribute, the length attribute, the unique constraints, and so
on... But if you want to test every aspect of your entity, you will write a
big piece of code for each entity! If you have a model with 10, 20 or more
entities, you see directly the quantity of work. JEUT is designed to
automate for you the testing of an entity. You have just to create a test
class that extends a specific JEUT test class and all the work is done for
you. The framework uses the annotations discovered via reflection API or the
XML files (orm.xml).

Do you understand the goal of JEUT?
