Great, could I request a Jira account to that end for "aj...@apache.org"? 
Thanks!

 I ended up building a dynamic bundle using TinyBundle containing my test 
 resources just the way I want them arranged, and injecting it like any 
 other bundle. I use a symbolic name to pick it back up inside the 
 container and use the resources.
 
 One note: I did need to put TinyBundle and BNDlib into the container to 
 support my test resource bundle, but that wasn't a big deal. I will pack 
 that part into a new Option or even pack the whole kit and kaboodle into a 
 some kind of "TestResourceOption". Would this be a useful PR, or would 
 folks rather have (as Christoph Läubrich mentions) the ability to directly 
 include resources into the test probe (which does seem a bit simpler)?

First step would be to open an Jira ticket so you (or any other team

Re: [pax-exam] Data for tests?

I think an option to include a resource into the test-probe is the most 
generic, simple and natural way. For special and/or advanced usage 
szenarios the tinybundle option can still be used.
Maybe it would even be possible to have (as an extra) some sort of 
includeMavenResources() option that builds on top of this feature and 
fetches all resources from scr/test/resources/ and includes them since 
that is what one would exspect when working with maven.

Re: [pax-exam] Data for tests?

['Christoph Läubrich' via OPS4J]

The problem is that resources are not packed inside the bundle probe.

Instead af working with classpathentries etc. directly in your 
test-probe, you can create a "test-resource-bundle" that includes all 
resources needed for the test, and include this in your test-setup, 
beside the resources, your bundle should include a class or interface in 
a package you export. You can the use 
MyTestResources.class.getClassloader().getResource() to fetch 
resources from there, or even create helper methods to prepare those 
resources (e.g. return a properties or parsed XML file or whatever). 
This is the most generic aproach.


You can even build a bundle on-the-fly with tinyBundles() if you do not 
want to create a new maven module.


Beside this, it might be a good idea to have a pax exam option to 
include resources in the test-probe.

Re: [pax-exam] Data for tests?

['Achim Nierbeck' via OPS4J]

Hi,

this is a rather interesting problem you need to solve.
As your tests do run within the OSGi environment you'll need to use some
OSGi ways of requesting the file.
Best is to include it in your classpath, as you'll never know what the
actual location on the system path is.
Right now I'd consider the Bundle.getEntry approach as being the best to
match.

regards, Achim

[pax-exam] Data for tests?

[sorok...@gmail.com]

Hi, OPS4J folks,

I'm building up some tests using Pax Exam with Apache Camel in Apache Karaf. 
The basic form of each test is just "Make an HTTP request to a given URI with a 
Camel route behind it, then compare the response with a known-good answer."

I'd like to include my known-good answers as data files (they are RDF and have 
well-known serializations) instead of inline strings, but I'm not totally sure 
about the best way to do that. I've been tinkering with adding them to the 
source tree and using Bundle.getEntry() and so forth, but this seems rather 
fragile.

Is there an accepted pattern for this use case, i.e. bringing data files along 
with the code for a test probe?

I hope this is a reasonable question to ask this forum. Thanks for the 
excellent product that is Pax Exam. It's definitely the best way to do testing 
with Karaf!
