Hints and Tips
If using JDO/DataNucleus
When running integration tests through the IDE, and if using the JDO/DataNucleus ORM, then make sure the module(s) with entities have been enhanced first.
If using IntelliJ, we recommend creating a run Maven configuration that runs
datanucleus:enhance, and then pinning the configuration once run as a tab in the "Debug" window for easy access.
