test transaction propagation with service and DAO

I have a service method of the service class, which is a Spring bean, that looks like

@Transactional
public void doThis() {
    dao.d1();
    dao.d2();
}

and in my DAO class, which extends Spring's NamedParameterJdbcDaoSupport. I have it set up as

@Transactional(propagation = Propagation.MANDATORY)
public void d1(){...}

@Transactional(propagation = Propagation.MANDATORY)
public void d2(){...}

and the configuration looks like

<tx:annotation-driven proxy-target-class="true" transaction-manager="transactionManager" />

Now my question is, how can I integration test it in Spring context? I have tested my DAO with AbstractTransactionalJUnit4SpringContextTests and an embedded database. how will I test the chain of service and DAO now so if dao throws a RuntimeException, I can see the whole transaction is rolled back?

Hope I explain it well. Any hints/suggestions are welcome
