Let's say we have a code like the following (I got the code frome here):

@Transactional
private def unitaryOperationUpdate {

    Integer roleId = params.roleSelector.toInteger()
    def roleInstance = Role.findById(roleId)
    UserRol.removeAll userInstance
    UserRol.create userInstance, roleInstance
}

If some error happened between removeAll and create, how could we check ourselves if the rollback is working properly?

You can look at your data before and after. If rollback happens all changes should be reverted. – Alidad Aug 31 '13 at 12:20
So how to produce an error between `removeAll` and `create` manually @Alidad? – chelder Aug 31 '13 at 13:08

You can throw exception. Not the best approach but you can test it. – Alidad Aug 31 '13 at 13:10
