The arquillian-jbossas-managed works for me, haven't played around that much with the other alternatives...
Thanks Nicklas! I thought I had tried arquillian-jbossas-managed, but maybe I hadn't. Or at least didn't have the config right. I am having other problems now (trying to inject a dao class in the CDI bean under test), but at least I am feeling much more on the right path now. Will post again if I have any problems that I can't get through after research. Thanks again!
