No need of any additional implementation to remove DB objects persisted by Unit test methods

If you have configured your setup with following configurations, no need to remove the DB objects which were persisted by unit test methods.

"In the TestContext framework, transactions are managed by the TransactionalTestExecutionListener which is configured by default, even if you do not explicitly declare @TestExecutionListeners on your test class. To enable support for transactions, however, you must configure a PlatformTransactionManager bean in the ApplicationContext that is loaded via @ContextConfiguration semantics (further details are provided below). In addition, you must declare Spring’s @Transactional annotation either at the class or method level for your tests."
