Hello,

I have a project that uses Thorntail, and Arquillian for testing.

I have configured JaCoCo 0.8.5 to measure my code coverage but it does not detect the lines on which it has passed. Therefore, it returns a report with 0% coverage while the test function is passed.

The report that is generated is located under target\site\jacoco.

To reproduce the problem, I run the command mvn clean verify.

It may not be a bug but more of a configuration issue.

Can you help me please?

I can send you the code that isolates the problem and allows me to reproduce it systematically.

Below you will find part of the files.

Dear Evgeny,

Thanks for your help and sorry to answer you so late.

I carried out a first test which you will find here : https://drive.google.com/file/d/13PM0KIV35FxEmn9KnccPsT1wTGibvehA/view?usp=sharing

In this one, JaCoCo is configured with the default mode. But, there is no hyperlink in the session page.
So I worked on a second test that you will find here : https://drive.google.com/file/d/1Yi2TsCYF7uA735SXqfbgAqWtR0WDB6yh/view?usp=sharing
In this one, JaCoCo is configured in offline mode. However, I do not have a session in the session page.

Best Regards,

Rémi Ollagnier

As stated on page https://www.jacoco.org/jacoco/trunk/doc/prepare-agent-mojo.html

Prepares a property pointing to the JaCoCo runtime agent that can be passed as a VM argument to the application under test.

Your tests start Wildfly in a separate JVM, so please make sure that this JVM receives the above argument.

Seems that you use Arquillian to start Wildfly, so please refer to Arquillian documentation about how to pass arguments.

For example after modification in attached javaVmArguments.patch

following report is generated

Dear Evgeny,

Thank you so much, I managed to get the code coverage with your corrections.

But, it's not work on Windows 10. I run the command on my RHEL 7.6 with the same code and always fine.

Is there a specific configuration for Windows?

Best regards,

Rémi Ollagnier

Usage of JaCoCo is the same on Windows as on other platforms:

JaCoCo agent should be passed to JVM using "-javaagent" argument
JVM should be terminated gracefully so that JVM shutdown hook registered by JaCoCo can write data on disk, note that to avoid JVM bugs such as https://bugs.openjdk.java.net/browse/JDK-8154017 you should use the latest updates of JVM

And as was already said in my previous email:

How to do this properly for JVM with Wildfly started by Arquillian - is the question for Arquillian/Wildfly experts/developers.

As well as the questions of different behavior of Arquillian/Wildfly on different platforms.

Rémi Ollagnier
