Junit test not rolling back after transaction - spring

Question

I'm trying to unit test some persistence code and I run into the problem that the database hangs on to the rows creating in previous tests. I am also using Hibernate Search although this is not reflected in the code I'm sharing here.
I'm using Spring 3.1.x, Hibernate 4.x and HSQLDB 2.3.2

Answer 1

Try adding #Transactional annotation on test class. http://docs.spring.io/spring/docs/2.0.x/api/org/springframework/transaction/annotation/Transactional.html

Answer 2

Try adding transaction interceptor:
<beans xmlns:tx="http://www.springframework.org/schema/tx"
xsi:schemaLocation="
...
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx-3.0.xsd">
<tx:annotation-driven transaction-manager="transactionManager"/>
</beans>

Answer 3

Extend AbstractTransactionalJunit4SpringContextTests or add #TestExecutionListeners(TransactionalTestExecutionListener.class).

Answer 4

So, I finally got this working by specifying defaultAutoCommit=false on the BoneCPDatasource. AFAIK this is way too low level for this configuration, and therefore possibly wrong. But at least it's working.
