This post is an addition to the post Unit Test Your DB Schema and Named Queries. It shows how to use the TestNG Annotations in order to simulate a lightweight EJB container enabling you to test your persistence layer (DAO, entity classes and similar). If you are using JBoss 6 you may use the embedded EB container. EJB3Unit supports testing Enterprise Beans, too. But I couldn’t get the latter to run smoothly and I do not use the former, yet. So if you are still tied to the old Java EE 5 world you might benefit form this solution.

Unit Testing of DB Schema and Named Queries

Therefore, tests being run during the build process can help to detect problems before your software is applied in a productive environment. In a EJB 3.0 application you may validate your DB-Schema and your named queries in a unit test, by starting up the EntityManagerFactory. It is one of the fine new features of JPA 1.0 (related to CMP in EJB 2.x) that you are able to use it without a container in a normal Java application. For your test you need a jndi.properties in your classpath:
