I prefer to move the karaf testing framework to pax. I think it makes
sense to keep it near the base test framework.
That said I am willing to help improve the pax karaf features and
convert the current karaf 3 tests to the new framework.

All@Karaf,
at OPS4J, there is an ongoing discussion about Karaf support in Pax
Exam, and in my role of Pax Exam Project Lead, I would like to bring
up this subject to the Karaf team, hoping to set up a roadmap for
making Karaf work with Pax Exam 3.x.
Some background:
- The Karaf Test Container, originally started by Andreas Pieber as a
separate project, is now part of the Karaf code base.
- On Karaf trunk, this container is based on Pax Exam 2.6.0.
- The container and existing tests use some Pax Exam APIs that were
deprecated in Pax Exam 2.4.0 and have been removed in Pax Exam 3.0.0,
along with the deprecrated Pax Runner Test Container.
- For this reason, people using Pax Exam to test Karaf-based
applications can't simply upgrade to Pax Exam 3.0.0. (Unfortunately,
nobody noticed or complained about that in the pre-3.0.0 release phase
of Pax Exam.)
- New Pax Exam options for provisioning Karaf features have been
contributed by Christoph Läubrich to Pax Exam master (targeting 3.1.0
or later), currently not backed by any integration tests.
Summing up the discussion [1] at OPS4J so far, we would like to
achieve the following goals:
- Tests based on the Karaf Exam Container (including but not limited
to integration tests of the Karaf project) can be upgraded to Pax Exam
3.x with little or no code changes.
- If any future refactorings either in Exam or in Karaf break the
Karaf Exam container, there is a bunch of failing regression tests in
at least one of the two projects.
- The Karaf Exam Container and all Karaf-specific Exam options are
centralized either in Apache Karaf or in OPS4J Pax Exam, to avoid
tangled responsibilities between two communities.
Those of you who've watched the progress of Pax Exam towards 3.0.0
will know that Pax Exam now offers a whole lot of test containers for
third-party runtimes like GlassFish, JBoss AS, Tomcat etc., backed by
a fairly extensive regression test matrix. So a Karaf test container
would be just another member of the family.
On the other hand, it might make sense to move the recent
Karaf-related additions from Pax Exam to the Karaf project.
To be sure, nobody at OPS4J wants to rip out a chunk of the Karaf
codebase just to make Pax Exam bigger ;-)
The basic question is, what is the best way to make things work
smoothly for all Karaf-cum-Exam users - I'm offering my support, and
I'm open to all options.
So much for now - I'm looking forward to hearing your opinions.
