hi all, i have been attempting to convert my existing JPA code over to GAE.
All is working so far except for the unit tests. i read code.google.com/appengine/docs/java/tools/localunittesting.html but it doesnt describe how to get an entityManager involved in usefull unit tests. so this is my test. please advise how to achieve the functionality in this test. @Test public void findFriendsSimple() { PositionUser user1 = new PositionUser(); user1.setFirstName("john"); user1.setLastName("smith"); PositionUser user2 = new PositionUser(); user2.setFirstName("mary"); user2.setLastName("smith"); PositionUser user3 = new PositionUser(); user3.setFirstName("barney"); user3.setLastName("smith"); em.persist(user2); em.persist(user3); //em.flush(); <--- can use flush for non transaction test user1.getFriends().add(user2.getKey()); user1.getFriends().add(user3.getKey()); em.persist(user1); //em.flush(); <--- can use flush for non transaction test Query query = em.createNamedQuery(PositionUser.FIND_FRIENDS); query.setParameter("userKey", user1.getKey()); List resultList = query.getResultList(); assertEquals( 2, resultList.size() ); } the assert is triggered java.lang.AssertionError: expected:<2> but was:<0> this is because the entitymanager wont detect the persisted entities that arent in a transaction. ok no problem, i will add transactions. But when i do it complains that i am adding multiple groups in a single transaction. So besides the simple gae sample unit test, how are others writting useful unit tests in gae? any help is most appreciated -lp -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.
