The project shows how to create integration tests for a JPA-based DAO using a real database and scheme managed by by Liquibase.
Typical approach to JPA tests in the JavaEE environment is based on in-memory databases and automatic creation of the database schema based on annonations. That's fine, except that's not how application actually works when deployed in production.
Native SQL is magic wand in JPA, but it also dramatically increases the value of integration tests executed against production database.
