As far as testing goes, here are a few things to help test the updated package:
1. After installing the test snap, running "pa-race" repeatedly should always fail. This is in comparison with the old package where it will occasionally succeed.
2. Running "/snap/pa-race/current/bin/bug" directly (i.e. the same program outside of confinement) should always succeed.
3. Running "snap run --shell some-classic-snap" and then "/snap/pa-race/current/bin/bug" from that shell should always succeed.
Some of the tests from the plan in bug 1781428 would be worth verifying too.
