@Stefan Lecho: I have good experiences doing unit testing with a JPA provider that is configured by Spring to connect to an in-memory HSQLDB database.

Which best practices exist for testing JPA classes without a container, more specifically how can the “@PersistenceContext” work correctly without a container ?

“(Ever tried to refactor 50+ insert statements?).”

Yes. No big deal.
You can write this thing called a “program” to regenerate your insert statements.

Hi Vincent,

Luckily I have just finished a blog with some TDD tips . I think one of the main aspects is that in most applications it does not really matter what storage technology you use. As long as you define your tests in a high level language you can easily change from in-memory to Oracle for instance. The good thing is that whenever you change you have tests that proof your code is still working.

Another tip specifically for inserting test data in the database: Don’t use SQL insert scripts and stay away from tools like DBUnit where you need to define your testdata in XML. Why? Because this really gets in your way when needing to refactor the database. (Ever tried to refactor 50+ insert statements?).
What I recommend is to setup your test data in java objects using Builder and ObjectMothers, then use your dao’s to insert those into the database.
