Moving this thread to the linaro-dev mailing list because I'd like it to be public discussion, and specifically to involve Rob since we talked about his interest in getting involved with LAVA development and especially the job dispatcher.

If we are already going down that path, seems it would be sensible to take it a step further and have defined sections. For example: Tests:[ { name:"LTP", testsuite:"abrek", subtest:"ltp", <---- not thrilled about that name "subtest", but can't think of something better to call it at the moment timeout:180, reboot_after:True }, { name:"echo test", testsuite:"shell", timeout:20 reboot_after:False } ] What do you think? Obviously, there would be other sections for things like defining the host characteristics, the image to deploy, etc. > >> >> > Other questions... >> What if we have a dependency, how does that get installed on the target >> image?
