/**
 * @author sturner AbstractIntegrationTestBase
 *
 * Based on the old BaseTransactionalIntegrationTest class: refactored to move
 * away from deprecated Spring classes and to the newer Spring TestContext
 * Framework.
 *
 * NOTE - this is now an abstract class. This does not change the usage, as the
 * old version of the class was only ever used as a base class for JUnit
 * classes.
 *
 * The list of context config locations can be overriden by coding
 * @ContextConfiguration in a base class.
 *
 * The class is marked as @Transactional, which means test methods in derived
 * classes will be run in a transaction and will be automatically rolled back on
 * completion. If you do not want transactional behavior in a test method,
 * annotate the method with @NotTransactional. If you do not want the automatic
 * rollback, annotate the method with @Rollback(false). BUT - normally our
 * "integration" tests should use a transaction and do rollback, so the defaults
 * should always be what you want.
