Hibernate for unit tests is configured to drop and create database to ensure its correctness. If you want to run it against real data base is not good idea to do it from unit test. I would recommend you to deploy them and then use console to execute them.
If you really want to run them from unit test then you must remove/change following property in hibernate config file:
<property name="hibernate.hbm2ddl.auto">create-drop</property>
please take a look at already prepared configuration file in distribution package/install/src/cfg/hibernate/jdbc
BTW, please use parent forum for this type of questions
