Prevent data from being deleted after test run with Hibernate / Spring / Maven / MySQL

I am using Hibernate / Spring / Maven / MySQL and unit tests with JUnit. Up to yesterday, my testdata persisted in the database even after the test run was completed. I configured the hell out of this day and all of the sudden all data are being deleted after every test run. Quite sure, this is no bug, but a config issue. Nevertheless, I am lost.

Thanks for suggestions.

Using @Rollback(value = false) annotation on your test case that creates the test data makes sure that the data doesnt get deleted.

Could you be running your tests inside a transaction and rollbacking it?
