I want to test integration of dao-layer with my service-layer in a unit-test. So I need to setup some data in my database (hsql). For this setup I need an own transaction at the begining of my testcase to ensure that all my setup is really commited to database before starting my testcase.
So here's what I want to achieve:
// NotTranactional
public void doTest {
// transaction begins
setup database
// commit transaction
service.doStuff() // doStuff is annotated @Transactional(propagation=Propagation.REQUIRED)
}
Here is my not working code:
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations={"/asynchUnit.xml"})
@DirtiesContext(classMode=ClassMode.AFTER_EACH_TEST_METHOD)
public class ReceiptServiceTest implements ApplicationContextAware {
@Autowired(required=true)
private UserHome userHome;
private ApplicationContext context;
@Before
@Transactional(propagation=Propagation.REQUIRED)
public void init() throws Exception {
User user = InitialCreator.createUser();
userHome.persist(user);
}
@Test
public void testDoSomething() {
...
}
}
Leading to this exception:
org.hibernate.HibernateException: No Hibernate Session bound to thread, and configuration does not allow creation of non-transactional one here

I dont know whats the right way to get the transaction around setup database.
What I tried:
@Before
@Transactional(propagation=Propagation.REQUIRED)
public void setup() {
setup database
}
- Spring seems not to start transaction in @Before-annotated methods. Beyond that, thats not what I really want, cause there are a lot merhods in my testclass which needs a slightly differnt setup, so I need several of that init-methods.
@Transactional(propagation=Propagation.REQUIRED)
public void setup() {
setup database
}
public void doTest {
init();
service.doStuff() // doStuff is annotated @Transactional(propagation=Propagation.REQUIRED)
}
-- init seems not to get started in transaction
What I dont want to do:
public void doTest {
// doing my own transaction-handling
setup database
// doing my own transaction-handling
service.doStuff() // doStuff is annotated @Transactional(propagation=Propagation.REQUIRED)
}
-- start mixing springs transaction-handling and my own seems to get pain in the ass.
@Transactional(propagation=Propagation.REQUIRED)
public void doTest {
setup database
service.doStuff()
}
-- I want to test as real as possible situation, so my service should start with a clean session and no transaction opened
So whats the right way to setup database for my testcase?
