It would be helpful to me... so I'm presuming others... to have a version of the commit() method similar to the following using the EntityTransaction interface as a model:

/**
* Commit the current resource transaction, writing any
* unflushed changes to the database. This version of the
* commit() method returns the number of SQL modification-
* related statements executed.
*
* @throws IllegalStateException if <code>isActive()</code> is false
* @throws RollbackException if the commit fails
*/
public int commits();

Perhaps obviously, this method would have immediate benefit in a (JUnit style) testing context - where it is difficult to assert if an "update" actually was persisted to the database.

For our own testing we generally accomplish this by setting a custom logger into the Session that monitors SQL logging.

The class is org.eclipse.persistence.testing.framework.QuerySQLTracker, available from our Git repository under testing.

Can you include a copy of the "assert" method you are using to ensure updates actually were persisted during unit testing?
