Pax Exam runs test twice - osgi

Question

This is my trivial Pax Exam test:
package ru.focusmedia.odp.server.datastore.itests;
import static org.ops4j.pax.exam.CoreOptions.felix;
import static org.ops4j.pax.exam.CoreOptions.options;
import javax.inject.Inject;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.ops4j.pax.exam.Option;
import org.ops4j.pax.exam.junit.Configuration;
import org.ops4j.pax.exam.junit.JUnit4TestRunner;
import org.osgi.framework.Bundle;
import org.osgi.framework.BundleContext;
/**
* #author Toni Menzel (tonit)
* #since Mar 3, 2009
*/
#RunWith(JUnit4TestRunner.class)
public class SampleTest {
#Inject
BundleContext bundleContext = null;
/**
* You will get a list of bundles installed by default plus your testcase,
* wrapped into a bundle called pax-exam-probe
*/
#Test
public void listBundles() {
for (Bundle b : bundleContext.getBundles()) {
System.out.println("Bundle " + b.getBundleId() + " : "
+ b.getSymbolicName());
}
}
#Configuration
public Option[] config() {
return options(felix());
}
}

I expect the test to be run once, but this is the actual result:

Why is the test being run on org.eclipse.osgi as well?

Answer 1

check transient dependency of equinox bundle for test scope and exclude it explicitly.
options(felix()); - is only for PaxRunner container. It's ignored by Native Container.
Native container uses OSGi frameworks from classpath.
Pax-Exam options

Answer 2

I had the same issue, one of my colleagues had me remove the #Configuration annotation from the method that returns Option[], and that fixed the issue.
