 *  <b>Purpose:</b>An instance of TestAdapter used for running any test
 *  in a three-tier architecture.
 *  <p>
 *  On wrapped tests each call to getSession().acquireUnitOfWork() will
 *  create units of work on separate ClientSessions, each with their own
 *  exclusive connection.
 *  @author  Stephen McRitchie
 *  @since   10 used for testing pessimistic locking where competing UnitOfWorks
 *  share a global cache, each have an exclusive connection, and can block each
 *  other.
