Filing this issue in response to the reference forum thread and this work:
https://github.com/panga/arquillian-extension-switchyard

Some interesting possibilities here:

• Unify our test behavior/support across test frameworks (SY TestRunner and Arquillian) through a shared set of classes/interfaces.
• Allow for Invoker injection into Arquillian test cases.
• Provide embedded container support for SY running within Arquillian (no EAP/WF involved).
• Lots more I haven't thought of!
