Spring JUnit JPA Transaction not rolling back - spring

Question

I am trying to test my DAO that uses JPA EntityManager to fetch and update entities. I have marked my unit test as Transactional and set the defaultRollback property to false. However, I don't see my transactions rolling back at the end of the test when throwing a rune time exception. The data is getting persisted in the DB. Here is my unit test code along with spring configuration. I am clearly missing something but havent been able to identify what.
Btw, the transaction is RESOURCE_LOCAL in the persistence.xml
#RunWith(SpringJUnit4ClassRunner.class)
#ContextConfiguration(locations={"classpath:spring/test-jpa.xml"})
#TestExecutionListeners(
{ DependencyInjectionTestExecutionListener.class,
TransactionalTestExecutionListener.class,
DbUnitTestExecutionListener.class
})
#TransactionConfiguration(defaultRollback=false)
#Transactional
public class JpaTests {
#PersistenceContext
EntityManage em;
#Test
public void testTransactionQueueManager() {
Object entity = em.find(1);
//code to update entity omitted.
entity = em.merge(entity);
em.flush();
throw new RuntimeException
}
}
Spring Configuration
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"
destroy-method="close">
<property name="driverClassName" value="${jpa.driverclassname}" />
<property name="url" value="${jpa.url}" />

<property name="password" value="${jpa.password}" />
</bean>
<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">

Answer 1

Your configuration seems fine.
There could be different reasons for the unexpected commit, maybe a datasource with autocommit mode or a non transaction compliant database (mysql with MyISAM ?)
Did you check this thread Why are transactions not rolling back when using SpringJUnit4ClassRunner/MySQL/Spring/Hibernate ?

Answer 2

#TransactionConfiguration(defaultRollback=false)
might be the culprit. Try defaultRollback=true, that should rollback the transaction.

Answer 3

Adding rollbackFor may help, it's a common pitfall.
#Transactional(rollbackFor=Exception.class)
