summary: Check that snap timer services work
details: |
A snap service may define a timer declaring when the service must
be run automatically. Those timers translate to systemd timer
units.
This test verifies that the installation of a snap with timers, or
enabling of the snap, will create corresponding systemd timer. It
will also verify that removal or disabling of the snap will also
remove the timer units.
