[PROPOSAL] Convert OSGi integration test to pax-exam-karaf
Hi guys,
I'd like to propose to convert our osgi integration tests from pax-exam 1.x
to pax-exam-karaf (which uses pax-exam 2.x).
*The problem*
Our test are currently based on pax-exam 1.x. We build our test by creating
a pseudo karaf instance over pax-exam by installing all the bundles we need.
That is really cluttered and is really hard to maintain, since for every
change in karafs dependencies we have to go all over the bundle list and
see which artifacts were renamed, splitted or got new dependencies.
That's a problem we have nearly every time we upgrade the karaf version
inside the nmr.
*The side effect*
I think that this problem prevents us from adding more integration tests,
since maintenance will become unbearable.
But I do think that adding more tests is really needed. For example, we
don't have a test that can tell us that our container even starts (not to
say that bundle are started, or services are available).
*The proposed solution*
I propose to rewrite the integration tests based on
https://github.com/openengsb/labs-paxexam-karaf.
I have used this on several projects so far and it did really make a
difference for me. I would say its the "selenium tests" for karaf.
The value it brings to the table is that it allows you to run your tests
directly inside your custom distribution (in our case directly in
servicemix-nmr or servicemix distribution) and it save us the trouble of
building it bundle by bundle.
The tests run inside the real distribution with all its features available
(from deployers and managed service factories to admin features).
wdyt?

Me too, but the "apache" version of pax-exam-karaf is currently bound to
Karaf 3.0.0 and it complicates things as you already mentioned.

I would prefer to use the "Apache" version of the pax-exam-karaf ;)

Currently we don't have to refer to karaf trunk at all. We can just use
pax-exam-karaf (as is on github and released to maven central).

Yes yes, agree that Karaf PaxExam is compatible with Karaf 2.2.x.
I'm just talking about the dependencies in the POM.
As I said, it's not a big deal ;)

If you do this yes. BTW, there wouldn't be any problem here. "Karaf
PaxExam" is also backward compatible to 2.2.x. Still, I think
labs-paxexam-karaf is the better option till 3.0 is released (since you do
not have to rely on snapshots). As said, the switch is pretty simple
afterwards.

Andreas

Hi Andreas,
maybe I missed something, but AFAIR, "Karaf PaxExam" has been committed
only on Karaf trunk.
It means that in the SMX pom, I will have:
- karaf 2.2.x version (currently) for the SMX assemblies and unit tests
- karaf 3.0-SNAPSHOT only for the "Karaf PaxExam"
Am I wrong ?

Basically +1; The only real difference between pax-exam-karaf on github and
the code on karaf trunk are the namespaces. Therefore I think a start with
the github version is OK, since a switch to the one in karaf 3 (once it is
released) is extremly straight forward.
@JB I don't understand what you mean by double? for the smx distribution
basing on karaf 2.x simply use pax-exam-karaf and for those basing on
karaf-3 the karaf trunk version.
WDYT?
Kind regards,
Andreas

Agree,
but it means that we have a "double" dependency:
- karaf 2.2.4 for itests + assembly
- karaf 3.0-SNAPSHOT for PaxExam
It's not a big deal.

To be honest I don't see what is the benefit of waiting for Karaf 3.0.0
really is.
pax-exam-karaf is also released independently and that allows us to use it
straight ahead.

Hi Ioannis,
Agree with the proposed solution, but I will wait the update to Karaf 3.0.
The Karaf PaxExam is now part of the Karaf trunk (in tooling).
So we can switch to "Karaf PaxExam" when upgrading to Karaf 3.0.
Regards
JB
