How to pass JVM args to child processes?

[Magnus Granander]

Hi!

I'm currently working on a project that need to send environment args to the running process to work. As it is now, PIT will not work out of the box. I don't think I'm the only one out there that have this issue.

The documentation states this clearly:

"

• mainProcessJvmArgs - JVM arguments to be used when launching the main PIT process; make a note that PIT itself launches another Java processes for mutation testing execution and usually jvmArgs should be used to for example increase maximum memory size (since 0.33.0 - see #7);

"

Is there some way to pass the args to the actual running process and not just the main PIT process?

Thanks!

Hi Magnus,

took me a moment to figure out that you're using the gradle plugin. mainProcessJvmArgs is not a regular Pitest argument but supported by the gradle plugin only.

Nevertheless have you tried jvmArgs which is a regular Pitest parameter? jvmArgs can be used to specify jvm flags as well as environment variables using -Dsome.key=ABC syntax. The arguments passed to jvmArgs will be passed to the child processes running the tests - at least this is how maven and ant plugins work. But as far as I can tell reading the gradle examples in the gradle documentation this should work with gradle plugin, too.

Stefan
