How do I make jacoco take into account the coverage of what is run by tests as Runtime.exec(...) or ProcessBuilder(...).start()?

[Nicos109]

Hello,

I'd like the jacoco report to take into consideraton the parts of the code covered by other jvms started with a Runtime.exec("java", "Main"). Is there a way to do this ?

Thanks

Nicolas

Hi Nicolas,

if you start a new Java process and want to collect coverage for it make sure to also configure the JaCoCo agent for it. See documentation:

https://www.jacoco.org/jacoco/trunk/doc/agent.html

Hi,

Thanks for your reply. I managed to configure the agent for each individual execution which generates a jacoco_xxx.exec. Now I have a lot of exec files and not sure what to do with them. Also I've read on another answer of yours that jacoco needs access to the class files directly from the project. In fact my class files are not part of the project, they're generated on the fly. Is this going to work for me ? Maybe I'm better off creating a maven goal that will generate all these classes inside the project before test phase  ?

Thanks

Nicolas

Hi Nicolas,

it really depends what you want to create the report for: For all executions incl. the parent process? For every execution separately?

In any case JaCoCo offers a lot of flexibility:

* Exec files: Can be written to individual files, can be merged afterwards with the merge commands. Or can be directly all written to the same file.

* Class files: You need them at the point in time when you create the report. You only need those files which should be shown.
