arquillian-jacoco extension working?

[nickarls]

Anyone got it to work on a remote connector?

I have

I see the agent launched, the test is executed on the remote container, the reports are generate but coverage shows 0%

pointers?

[nickarls]

Umm. When exporting the test archive, I don't see any jacoco-stuff included. How can it instrument stuff on the remote JVM?

[nickarls]

In https://github.com/arquillian/arquillian-extension-jacoco/issues/21 bmajsak mentioned a forthcoming howto, any news on that?

[nickarls]

Any help would be... helpful

I got it working with the following configuration both on remote and managed container on wildfly 13.

Since it I have a multimodule project in each child pom with tests I have this in pom

I hope it will help you

[nickarls]

Thanks, I'll try to distill that down to a bare minimum

[nickarls]

It would be interesting to know how the arquillian jacoco extension is supposed to work in a docker environment. I assume the bytecode enhanchement is done to the test archive in the normal way but what happens next?

Since the actual test executions happens in a different JVM/container, does that WildFly have to be started with some agent? And aren't the execution statistics generated in the container? How is it supposed to be fetched into the JVM that started the build?

[nickarls]

The arquillian-jacoco docs say that

When using the Arquillian Jacoco Extension with Sonar you only need to depend on the Arquillian Jacoco Extension. Sonar will handle the setup of Jacoco for you.

apparently you still need the sonar-jacoco-listeners hooked up(?)

I my jenkins console output I see

[INFO] Analysing /var/jenkins_home/workspace/Concept7/target/jacoco.exec

[INFO] No information about coverage per test.

the jacoco.exec has other content, though so it looks like jacoco is not picking up the executions happening in the remote server. Does it have to be started with some agent parameters?
