integration testing with karaf

Hi,

I've been reading and trying to write some integration testing using karaf,
looking at
http://karaf.apache.org/manual/latest/developers-guide/writing-tests.html
seems rather straightforward.  

However, I am getting java.lang.NoClassDefFoundError:
org/ops4j/pax/exam/options/extra/FeaturesScannerProvisionOption which isn't
in pax-exam 3.4.0

But if i use 2.6.0, it'll satisfy the requirement but it will raise
java.lang.NoClassDefFoundError:
org/ops4j/pax/exam/ExamConfigurationException

Has anyone created integration test using gradle successfully?

Thanks,

Ken

Can you try with the example from the pax exam site?

Ken, I'm doing exactly that in my tests to make sure a certain feature is 
ready to use (all bundles active). Did you have a look?

No

it's the opposite: org.apache.karaf.tooling.exam.container is 
deprecated, you should use pax-exam-container-karaf >= 3.4.0.

It's what Karaf uses for its own itests.

erf,

no the pax-exam is the one to use, the Karaf one is the old one that is
deprecated :)

Here's the stack trace when the test fails.

It's maybe due to DeadLock issue:
https://ops4j1.jira.com/browse/PAXEXAM-609

Do you have something in log/messages when container doesn't come up ?

I managed to figure the useDeployFolder flag and it is now working.

However, it seems as though the deeper I dig into the pax-exam, the more
problems I find.  Sometimes I get a RuntimeException saying "container never
came up".  Somehow, it is not starting in a timely fashion and I am only
starting 2 bundles from my features repo.  Are there any tricks to speed it
up?

Thanks

Maybe you let pax exam do the bundle install using the deploy folder of 
karaf.
Then it is possible that your test code runs before the bundle is installed.

Try this:
|.useDeployFolder(||false||)|
Then a feature file will be used and pax exam will make sure the bundle 
is started before your test runs.

In most pax exam tests you simply inject a service into the test. 
Besides providing the service for your test class this makes sure the bundle
containing the service is up and running.

jbonofre,

so org.ops4j.pax.exam:pax-exam-container-karaf:3.4.0 is deprecated and I
should be using
'org.apache.karaf.tooling.exam:org.apache.karaf.tooling.exam.container:3.0.0.RC1'
?

Also, issue arises :(  I am still playing around with pax-exam and trying to
install a bundle and see if it exist.  This is so I get the hang of things
before writing real integration tests.


and my check is as simple as

it doesn't seem to be able to find the bundle.

any suggestions as to what i am doing wrong?

Thanks,

Ken

Hi Ken,

pax-exam-container-karaf is now deprecated: it has been donated directly 
in pax-exam (you need at least pax-exam 3.4.0).

Christian, Oliver,

Thanks for the tips and I got the integration test to work.  

One last question - what is the difference between
org.apache.karaf.tooling.exam.container and pax-exam-container-karaf?

I am using pax-exam-container-karaf like Christian suggested and it works.

Thanks,

Ken

I had similar issues and got around by setting headers for Import- and Export-
Package in a test bundle:

integration-
