-/**
- * This class is the entry point for JPA tests. Test code should construct a
- * JpaTester in the <code>@Before</code> method and call {@link #start()} on it
- * in that method. Also, test code should call {@link #stop()} on it in the
- * <code>@After</code> method.
- *
- * This class is constructed with a description of the persistence unit to be
- * tested. The principle is that an existing <code>persistence.xml</code> can be
- * tested without change in unit test code.
- *
- * It then takes care of the following:
- * <ul>
- * <li>Creating an inmemory database for testing (default) or connecting to an
- * external database. See {@link DatabaseBuilder} for more information on how a
- * databse is obtained.</li>
- * <li>Drop all database tables that are related to the persistence unit under
- * test, including JPA provider specific tables.</li>
- * <li>Creating a datasource for the database and make the datasource available
- * through JNDI.</li>
- * <li>Creating the entity manager factory for JPA and configuring it in such a
- * way that schema creation happens. (Typically, schema creation will be
- * disabled in the persistence.xml but this utility enables it for unit test).</li>
- * <li>Creating a DBUnit database tester which is appropriately configured for
- * the persistence unit under test.</li>
- * </ul>
- *
- * The main entry point for all this functionality is the
- * {@link PersistenceUnitDescription} which describes the persistence unit and
- * must be provided at construction of the <code>JpaTester</code>
- *
- * NOTE: Persistence XML files should be explicitly configured with the classes
- * that are part of the persistence unit since scanning of classes does not work
- * correctly in a unit test environment. This is currently the only limitation.
