+ * This class is the entry point for JPA tests. Test code should construct a JpaTester in the
+ * @Before
method and call {@link #start()} on it in that method. Also, test code should
+ * call {@link #stop()} on it in the @After
method.
+ *
+ * This class is constructed with a description of the persistence unit to be tested. The principle is that
+ * an existing persistence.xml
can be tested without change in unit test code.
+ *
+ * It then takes care of the following:
+ *
JpaTester
+ *
+ * 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.
