    <p>I have no problem testing my DAO and services, but when I test <code>INSERT</code>s or <code>UPDATE</code>s I want to rollback the transaction and not effect my database.</p> <p>I'm using <code>@Transactional</code> inside my services to manage transactions. I want to know, is it possible to know if a transaction will be fine, but rollback it to prevent altering database?</p> <p>This is my Test:</p> <pre><code>@RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration(locations = "classpath:/META-INF/spring.cfg.xml") @TransactionConfiguration(defaultRollback=true) public class MyServiceTest extends AbstractJUnit38SpringContextTests { @Autowired private MyService myService; @BeforeClass public static void setUpClass() throws Exception { } @AfterClass public static void tearDownClass() throws Exception { } @Test public void testInsert(){ long id = myService.addPerson( "JUNIT" ); assertNotNull( id ); if( id &lt; 1 ){ fail(); } } } </code></pre> <p>The problem is that this test will fail because transaction was rollbacked, but the insert is OK! If I remove <code>@TransactionConfiguration(defaultRollback=true)</code> then the test pass but a new record will be inserted into database.</p> <pre><code>@Test @Transactional @Rollback(true) public void testInsert(){ long id = myService.addPerson( "JUNIT" ); assertNotNull(id); if( id &lt; 1 ){ fail(); } } </code></pre> <p>Now can test pass correctly, but rollback is ignored and the record is inserted into the database. I have annotated the method <code>addPerson()</code> inside myService with <code>@Transactional</code>, obviously. Why is the rollback being ignored?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
