If I use spock to implement my unit tests and my arquillian tests, it is not possible to run spock (unit) tests w/o Arquillian any more. Afaik this is possible if JUnit is used. Annotate them with @Arquillian -> running as Arquillian test; Don't annotate them -> running as "normal" unit tests.

I would like to have this behaviour with spock as well.
