Still about Hibernate, I have several JPA Entities grouped in a Persistence Unit that I need to test. So here is another quick and dirty howto titled “Unit test JPA Entities with in-memory database”.
Here I assume you already have written your entities java classes with correct annotations.
As I’m working with embedded Derby for a year, I first tried with it but procton (thank you procton) pointed me to another lightweight RDBMS.
So, in this how-to we will set up a unit-tests dedicated persistence unit and use HSQLDB as in-memory database for unit tests.
UPDATE: now that Apache Derby provide an in memory backend, I implemented the very same thing with it in a new post : Unit test JPA Entities with in-memory Derby/JavaDB
