OSGi Code Coverage during Integration Testing - maven

Question

I am running integration tests on OSGi bundles using SOAPUI. So far I have integrated SOAPUI with Maven which runs integration tests on OSGi bundles*(running in Apache Karaf)*. I am trying to find out how can I further enhance my pom.xml to calculate code coverage during runtime for the bundles?
Can anyone plz suggest some points?
I have the following pom.xml:

Answer 1

Answer:
I suggest that you should try Jacoco. Jacoco can be configured as a java agent, so it can work with any Java application. In this case, you should configure Jacoco on the Karaf server where you deploy the bundles.
You can configure it as a TCP server so you can check the coverage reports live from Eclipse (it has an Eclipse plugin as well to connect).
Extra:
We use Jacoco with our maven plugin that starts an OSGi container and runs tests on them within the integration-test phase of the build. In case felix or equinox is enough, you can use it as well.
It supports creating custom dist packages so if you bundle your Karaf server as a dist package, it could also be used. Sadly, there still not much documentation about creating custom server types.
