For my Raspberry Pi build/test automation regimen, there are two aspects of code that require root permissions, as they will not work with /dev/gpiomem (fwiw, one aspect is Pulse-Width Modulation functionality, the other deals with the Pi's hardware clock registers).

I obviously don't want to have the actual code up and randomly sudo, instead, a note in the docs will specify if these features are used, you'll need to setuid or run your script with sudo.

Likewise, I don't want to run the whole test suite with root, just two files.

I'm thinking something like the following which appears to work well:

use warnings;
use strict;

use Test::More;

if ($> != 0){
    system('sudo', 'prove', '-l', $0);
    exit;
}

is 1, 1, "ok";

done_testing();

Is this reasonable, or am I overlooking an easier or better way to do this?
