Question on running uboot_testpy with tbot

[Simon Glass]

Hi,

I am trying to run the pytests on my unit. The documentation doesn't really
explain how it works.

This is what I am trying:

$ tbot -vv -l kea.py -b rpi3.py -T tbot/contrib  -p 'testpy_args=["-k",
"help", "-vv"]' uboot_testpy
tbot starting ...

I don't see the output appearing and I'm not sure how pytest is sending the
commands to the board?
