I was testing the newest version of JBOSS 7.1.0. This version is full JEE 6 compatible.
Arquillian is a really nice testing framework! It's all plumbing related to the container life-cycle, archive deployment, framework initialization. It's handle context dependency injection of resources, business component like EJB. This kind of framework allow us to focus real integration testing.
