As a general principle that's probably a good guideline, but in this specific case . . . eeeh. Writing to a raw IP socket has historically depended on being done as root. If you're writing something which in the normal *NIX sense requires elevated privileges ((say) managing or changing effective UID, or writing to raw network devices) then unless you're running as root the code is not going to work.
Perhaps it hints at needing a more fine-grained permissions / capabilities framework that could automagically enable / disable tests where the current context is lacking (or provide gated access via something like sudo). Or maybe MOAR ENVIRONMENT VARIABLES to dictate the context.
