Would be great to go through the new book. Will there be a comparison of Spring ORM and Hibernate? Does it show how to use unit tests to test spring persistence with hibernate? does it go into detail on how to get reference data setup?
Testing and testing strategies is a significant component of our book. We discuss techniques for building unit and integration tests for your persistence layer, and cover approaches related to mocking, reference data seeding, automatic rollback at the end of a test, and more. The authors are all big fans of testing, and I think this is an area where Spring really shines, as it helps to decouple your layers and dependencies, encourages interface design, and makes testing more attainable.
Thanks for your question, and I look forward to speaking with you soon.
