I use:

sudo /home/dev/.cargo/bin/cargo test

so using the cargo installed in the dev account on my test machine.

That way I can build, clippy and generate docs etc as dev, but require
sudo for the tests.

I would love to know how to do it without the sudo, but as you suggest,
that would probably require some udev magic or something to set the
configfs and sysfs file permissions, as well as the gpiochips themselves,
and given the above works for me I've not had sufficient incentive to
look into it.

Cheers,
Kent.
