Here’s my test: @RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration(locations = { classpath:repositoryContextTest.xml }) @Transactional @TransactionConfiguration(defaultRollback = true) public

Here’s my test:

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "classpath:repositoryContextTest.xml" })
@Transactional
@TransactionConfiguration(defaultRollback = true)
public class SeasonITest {
@Autowired
private SeasonDao seasonDao;

@Test
public void createSeason() throws Exception {
    Season season = new Season();
    season.setName("2012");
    seasonDao.createSeason(season);
}

and the dataSource in my bean configuration file

<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"
    destroy-method="close">
    <property name="driverClassName" value="com.mysql.jdbc.Driver" />
    <property name="url" value="jdbc:mysql://localhost/tournament_system" />
    <property name="username" value="root" />
    <property name="password" value="root" />
    <property name="defaultAutoCommit" value="false"/>
    <property name="poolPreparedStatements" value="false"/>
    <property name="maxOpenPreparedStatements" value="0"/>
 </bean>

<bean id="transactionManager"
    class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
    <property name="dataSource" ref="dataSource" />
</bean>
<tx:annotation-driven transaction-manager="transactionManager" />

When I run this test there a new record is created in my database.

How can I rollback this transaction?

This is the log output I see:

2012-06-15 15:00:02,173 [main] INFO  - ionalTestExecutionListener - 
 Rolled back transaction after test execution for test context 
 [[TestContext@76db09 testClass = SeasonITest, 
   locations = array<String>['classpath:repositoryContextTest.xml'], 
   testInstance = org.toursys.repository.dao.SeasonITest@1265109, 
   testMethod = createSeason@SeasonITest, testException = [null]]]

UPDATE:

all answers below want to change logic or database engine what I dont want. So I am offering reputation point to the right answer:

Why when I have this: @TransactionConfiguration(defaultRollback = true) in transaction configuration tests are not rolled back and how I can fix it ?

    If you are using MySQL with MyISAM engine try switching to InnoDB.

    For more complicated test you will probably need a mocking framework or DB recreation.

    EDIT1:
    According to the documentation InnoDB is transactional with full ACID support while MyISAM has support for atomic operations. More reading: Transaction and Atomic Operation Differences

    EDIT2:
    In @TransactionConfiguration the default value for defaultRollback is true, so instead of commenting the line you should add @TransactionConfiguration(defaultRollback=false)
