that's indeed missing in the current implementation. Would you be so kind and open feature request in JIRA jira.jboss.org/jira/browse/ARQ (so you can track the progress )? [and assign it to the Persistence Extension component?]
I will take care of the rest
I've created the feature Request ARQ-1029 for this issue (https://issues.jboss.org/browse/ARQ-1029).
Until this feature is available, I'm going on to use DBUnit directly with Arquillian...
Thanks a lot for taking care of this
