如果没有Spring事务测试支持，如何编写Junit4测试？

Question

I would like to test transaction rollbacks in my application service. As a result i do not want to use spring's AbstractTransactionalJUnit4SpringContextTests with the @Transactional annotation as that wraps my test method in a transaction.

I know spring also offers AbstractJUnit4SpringContextTests for tests without transactions. However i need to have some transactions to save data into my database and also query data for assertions after running the service under test.

How can i write a Junit 4 spring transactional test without the default transaction test management?

Answer 1

Here is the answer to your question ;

@ContextConfiguration(value = "/applicationContext.xml")
public class JPASpringTest extends AbstractJUnit4SpringContextTests {
 @PersistenceContext(unitName="jpadenemelocal")
 EntityManager entityManager;

 @Autowired
 protected PlatformTransactionManager transactionManager;

 @Test
 public void testInsertRolManyToMany() {
 TransactionStatus status =  transactionManager.getTransaction(null);
 // your code   

 transactionManager.commit(status);
 }

}

Answer 2

The spring docs should cover this in their testing chapter

What you might want is to configure your test without the default TransactionalTestExecutionListener like this

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration
@TestExecutionListeners({DependencyInjectionTestExecutionListener.class,DirtiesContextTestExecutionListener.class})
public class SimpleTest {

    @Test
    public void testMethod() {
        // execute test logic...
   }
}
