$5+ for a GFCI tester? Its nothing more than a switch and
maybe a 15K resistor that connects hot (black) wire to safety
ground (green) wire. That same tester is what the TEST button
does - already inside the GFCI.

The TEST button puts the R between Line Black and Load White, or
the inverse. This so TEST works on GFI's with no ground.
(At least on the ones I've fiddled with..)
