summary: Ensure `snap debug refresh-app-awareness` command work
details: |
The command `snap debug refresh-app-awareness` should report internal
snapd state related to refresh-app-awareness like a list of monitored
snaps and refresh candidates.
# Ubuntu 14.04's special version of systemd doesn't have StartTransientUnit API.
systems: [-ubuntu-14.04-*]
prepare: |
# ensure no other refreshes interfere with the test
snap refresh
snap install test-snapd-sh
# retry is needed because we might need to wait for auto-refresh to finish first
tests.cleanup defer retry -n 50 --wait 1 snap remove --purge test-snapd-sh
debug: |
