Problems with initializing a pax-exam-based JUnit test

[prossman]

Hi,

following the instructions given on http://fusesource.com/docs/esb/4.2/deploy_osgi/BestPractices-PaxExam.html, I implemented a simple JUnit test (see attachment).

However, when I run it, I get an IllegalArgumentException ("URI is not hierarchical") originating from the call to Helper.getDefaultOptions(). In particular, the method MavenUtils.getFileFromClasspath() throws this exception when creating a new file from a URL ("return new File( fileURL.toURI() );"). The URL in question is:

file:/D:/Dev/.m2/repository/org/apache/servicemix/servicemix-shared/2010.01.0-fuse-02-00/servicemix-shared-2010.01.0-fuse-02-00.jar!/META-INF/maven/dependencies.properties

I've been looking for unit tests using pax-exam in the sources but couldn't find any. Any ideas what I might be doing wrong?

I'm using Fuse 4.2.0-fuse-02-00, Pax-Exam 1.2.1 and JDK 1.5.0_12. POMs for parent and actual project are attached.

Any help would be highly appreciated,

Ciao, Philipp

... forgot to attach the surefire output.

In the meanwhile, I reduced the configuration method to...

@Configuration

     public static Option[] configuration() throws Exception {

          return combine(

          // Default karaf environment

                    Helper.getDefaultOptions(),

                    // Test on both equinox and felix

                    equinox(), felix());

     }

... but to no avail; I still get the same error message.

I should mention that the files are where they should be.

I also checked the Felix Karaf mailing list archive. There is one other  entry  regarding Helper.getDefaultOptions(), but it seems to be unrelated.

FYI: the Fuse documentation about using Pax Exam is lacking an important part.

If you're using Helper.getDefaultOptions(), the method will look for a file META-INF/maven/dependencies.properties on the classpath. If it finds this file inside a JAR file, the code will fail as described before.

If you include...

... in the POM, the file will be generated in the target/classes folder. I found out about this after examining the Apache Felix Karaf integration tests.

Hi,

Thanks so much for this feedback.

Hi again,

Back in the day, I did some follow-up on this in order to get the tests up and running. However, I didn't manage, and as it seemed Pax-Exam related, I posted to their mailing list (http://permalink.gmane.org/gmane.comp.java.ops4j.general/10703) - but didn't get an answer so far.

As testing is getting into focus again, I was wondering if any of you Fuse guys has an idea of how to resolve the issue? (Please find attached the unit test in question)

Thanks,

Ciao, Philipp

Have you tried looking into the source code of Karaf? They must use that by themselves to test karaf.

At Apache Camel we got some osgi tests here

https://svn.apache.org/repos/asf/camel/trunk/tests/camel-itest-osgi/

Hi,

thanks for the hint. I've been looking at some tests that I found in the Felix Karaf sources, but haven't been investigating the Camel tests yet.

In the meanwhile, I found out that adding...

CoreOptions.systemProperty("org.osgi.framework.executionenvironment").value("J2SE-1.5,J2SE-1.4")

... solves the J2SE-1.4 issue described in the other thread.

Ciao, Philipp
