Hi Toni,

If i see right there is some kind of snapshot repro for OPS4j maybe that 
would be an Option? I'm not very familar with this I just have seen that 
when realeasing pax-wicket.
If thats not an option we might provide some kind of preview1 ... x

Re: [pax-exam] How to simulate beforeClass / afterClass hook *outside* of the OSGi container

2017-08-08 Thread Nicolas Brasey 
The server mode is not enough for me, as I would like to be able to write
tests against the OSGi services directly, I don't want to use the external
REST api.

Out of curiosity, and not knowing how exactly pax-exam works in details,
what is the reason the BeforeClass and AfterClass are not implemented ?

For me, the "simplest" would be to introduce certain hooks, for example:

a) BeforeClass (called once before the tests are executed, outside of the
container)
b) Probe bundle Activate (called once before the tests are executed, inside
of the container)
c) Probe bundle Deactivate (called once after the tests, inside the
container)
d) AfterClass (called once after the tests are executed, outside of the
container)

Maybe the same for the before and after hooks. One hook called from
outside, one from inside.

My 2 cents...

Nicolas

 Hi,

 just one question came to my mind, regarding your scenario.
 For your Integration tests you don't seem to rely on testing the
 internals of the OSGi container, right?
 In that case how about starting the Pax Exam tests as server tests,
 that way you only need to call externally available interfaces and can make
 sure you have neo4j started prior to that.

This is the very simple server mode (i did that back then). If it is enough
for you, sure. No big deal. You don't get any lifecycle integration with
your test framework and you need to do the configuration for accessing your

 Hi Christoph,

 Yes, that is exactly what I tried already, to bundle neo4j and all the
 dependencies with the maven shade plugin (like the ones in service mix
 bundles). I realized that this is not really ideal for the following
 reasons:

 1) The build time exploded, to create this huge jar takes more than
 1minutes and 30 secs
 2) The pom.xml is far from being straight forward to write, you need
 to have a good understanding of the internal structure of neo4j in order to
 maintain it. Also, I'm afraid this is time consuming on the long term and
 will requires tricky changes for each major release of neo4j.
 3) It was not even working! I had issues with neo4j internal way of
 loading modules with the java 6 ServiceLoader mechanism, which did not find
 http services for reasons I still ignore...

 Anyway, I finally gave up fighting with it ;-)

Re: [pax-exam] How to simulate beforeClass / afterClass hook *outside* of the OSGi container

2017-08-08 Thread Toni Menzel 
@Nicolas, I think your use case is a prime example out-of-container tests
that will become more accessible with Exam 5. (Acceptance Test API).
Here's the status:

   - There is a way to bootstrap a Test Container using the typical Exam
   Option DSL (done)
   - There is a very simple Rest Client API based on Rest Assured. That is
   really minimal and I am not sure if we just let Rest Assured do the job or
   keep being it an implementation detail.
  - Why keep it as an implementation detail? Rest Assured is such a
  broad API, confusing at times, many ways to do the same thing.
For example,
  there is a java object mapper but also groovy expression language. Two
  approaches, to do the same thing: evaluate HTTP responses.
  - Why expose Rest Assured? It's already a broad DSL that some people
  may already be familiar with. And building abstractions over abstractions
  is an anti-pattern. Pax Exam should not fall into this trap.
   - There another client that makes OSGi Services available to Acceptance
   Tests via Tunneling the request to the container. The tunneling part is
   important because I want any OSGi service to be accessible, not just the
   ones designed for serialization. (not safe in all cases but better than no
   access at all) (in progress)

Once this is done, we will look forward to a Pax Exam 5.0 Milestone 1
release. (Christoph, there is still a lot to be done, even breaking
changes.But I'd like to see early feedback on the many areas Exam 5 brings.
WDYT?)

Hi Achim,

No, I'm not so much interested to test the OSGi mechanics, I want to have
high level business tests on our business layer which is a set of OSGi
services. This requires the database and the messaging system to run as
well.

In fact, our app provides only rest api's from outside, and we have already
a set of mocha integration tests. Mocha is fine for testing rest message
structure and non-regression at the level but a little cumbersome and hard
to maintain when it comes to test more complicated business scenarios. That
is why I'm looking for a Java API in order to implement those tests,
pax-exam is ideal for me in that context.

Cheers,
Nicolas

 Hi,

 needs to have a database (neo4j) that is not OSGi friendly running before

 Also, neo4j provides a embedded server that works extremely well
 outside of an OSGi container, but I can't find a way to start this embedded
 server with pax-exam outside of the container before the pax-exam machinery
 is starting.

 The idea is to start the database in the non-OSGi context when the
 pax-runner is starting, something like the beforeClass, and stop the
 database after all the tests are finished ala afterClass.

 Does anyone has an idea how to do this ?

Re: [pax-exam] How to simulate beforeClass / afterClass hook *outside* of the OSGi container

2017-08-07 Thread Nicolas Brasey 
Hi Christoph,

Yes, that is exactly what I tried already, to bundle neo4j and all the
dependencies with the maven shade plugin (like the ones in service mix
bundles). I realized that this is not really ideal for the following
reasons:

1) The build time exploded, to create this huge jar takes more than
1minutes and 30 secs
2) The pom.xml is far from being straight forward to write, you need to
have a good understanding of the internal structure of neo4j in order to
maintain it. Also, I'm afraid this is time consuming on the long term and
will requires tricky changes for each major release of neo4j.
3) It was not even working! I had issues with neo4j internal way of loading
modules with the java 6 ServiceLoader mechanism, which did not find http
services for reasons I still ignore...

Anyway, I finally gave up fighting with it ;-)

Re: [pax-exam] How to simulate beforeClass / afterClass hook *outside* of the OSGi container

2017-08-05 Thread Niclas Hedhman 
I thought I should chip in and point out that Junit 5 ahs received the
entire extension mechanism, and both Rules and RunWith constructs are
deprecated, and implemented using the new extension system.

Perhaps it would make more sense for new functionality in Pax Exam to look
forward to JUnit 5.

Just my 2 sen.

2017-08-05 Thread 'Christoph Läubrich' via OPS4J 
Even though neo4j is not "osgi-friendly" (what ever that means ;-) you 
can create abundle that embedds all that neo4j requires, add an 
Activator that starts up your db and provide a custom service to trigger 
"after-test-checks" in whatever way you need. In your test you can the 
collect the service to


a) make sure the db is up and running
b) fire your checks whenever needed

So, about the imports: yes, well there used to be an option to let you mark
all generated imports to be optional for the probe. Have to look at this.

About the Acceptance Driver: yes it will work with any Pax Exam Test
Container. Stay tuned.

About the pre/post hooks: can you try implementing a Junit Rule?
https://github.com/junit-team/junit4/wiki/Rules (see
ExternalResourcesRule). This will give you the right amount of control.
But, I guess you will still get superfluous (and unresolvable) imports for

2017-08-04 Thread Nicolas Brasey 
Hi Tony,

Thanks a lot for your answer.

I think what you are working on is absolutely great, and I think it would
also perfectly fit for our needs. Starting the OSGi container from a junit
rule makes the tests cleaner. I guess this would also work with Karaf,
right ? But, just for the curiosity, how do you plan to access the OSGi
service from outside the container ? And when do you plan to push your
local branch ? :-)

2) Yes I tried booting neo4j from the @Configuration method, but there 2
issues IMHO:
a) It provides only a way to start neo4j, obviously no hook to run some
post tests code
b) since the configure code is also deployed as an OSGi bundle, it forces
you to make sure the  does not include the neo4j packages,
which cannot be resolved. It is feasible, but this is hard work and I'm not
sure about the maintainability of this over the time

3) Not sure I understood your proposal with the RunWith. Do you mean
implementing my own Junit runner that wraps the PaxExam runner, and run my
tests with it ?


Cheers,
Nicolas

Currently, only the rest client is available (using RestAssured), but I a
new one making internal services available to the test automatically is
already on my local branch.

In any way, we also could think of making out-of-container setup code
available in regular "@RunWith(PaxExam.class)" tests. Did you try booting
Neo4j inside the @Configuration method? that is executed before the OSGi
container is launched, so it does run in plain java.

Another try: did you try using a Junit Rule with "@RunWith()"? this should
work, too.
