hi all,
i am attempting to unit test my JPA code in a Spring unit test.
i read all the doco about gae unit tests.
i have this working in normal hibernate JPA with a specific tx
manager.
I cant see how the txManager is wired up.
however i get the following error
javax.persistence.TransactionRequiredException: This operation
requires a transaction yet it is not active

the test is simple enuff
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "classpath:WEB-INF/entitymanager-
context.xml", "classpath:WEB-INF/applicationContext.xml" })
@TestExecutionListeners( { DependencyInjectionTestExecutionListener.class })
@TransactionConfiguration( defaultRollback=false,
transactionManager="transactionManager")
@Transactional
public abstract class MyTestCase {
private final LocalServiceTestHelper helper =
new LocalServiceTestHelper(new
LocalDatastoreServiceTestConfig());
@PersistenceContext
protected
EntityManager em;
@Test
public void findFriendsSimple() {
PositionUser user1 = new PositionUser();
user1.setFirstName("john");
user1.setLastName("smith");
user1.setGeohash(Geohash.encode(lat+=0.0001, lon));
em.persist(user1);
em.flush(); <----- throws here
PositionUser find = em.find(PositionUser.class,
user1.getKey());
assertEquals( "john", find.getFirstName());
assertEquals( 2, find.getFriends().size() );
System.out.println("----------running query now");
Query query = em.createNamedQuery(PositionUser.FIND_FRIENDS);
query.setParameter("userKey", user1.getKey());
List resultList = query.getResultList();
assertEquals( 2, resultList.size() );
}
