Hi, I pushed the PR that enables us to easily switch from one DB to another during testing. I summarized the whole process here <https://developer.jboss.org/wiki/HowToRundebugTestsWithoutUsingTheHiberna... . Because of a bug in Wiki platform (when I edit I see an old version and not the current one), I'll add an extra option which I found the simplest of all. Considering I want to run a unit test on the hibernate-core and the current hibernate.properties was generated for H2. 1. I usually delete it: hibernate-orm\hibernate-core\target\resources\test\hibernate.properties 2. Then I run gradle processTestResources -Pdb=pgsql 3. Afterwards, I can simply run the test on my IDE and it will use PostgreSQL Let me know what you think. Vlad
