If the goal was to test the breaker, the best practice
would be to disconnect the load wiring at the breaker
and connect some wort of temporary test hookup.
There are so many ways a deliberate short (done with a
screwdriver) could have unintended consequences. At
the very least, you would leave arc marks on the
binding screws and junction boxes, and mess up the
screwdriver. And what if the breaker really was bad,
and the huge current surge got the screwdriver firmly
welded in place?
