Hi, I was unclear if the unittest need to be in /tests or in /src/.../arubaos/tests/

also, didn't figure out how I could run them localy.

ok, sorry for all those delay, took a while to get back on this since I was making inquiry within my company to see if I was allowed to submit such code etc...

Apparently I am ok to submit such code, but neeed to do so on my work email, so I will cancel this PR and re-submit with my work email [email protected]
