summary: Check that refresh-modes works
details: |
Snapd services can be configured to control whether should be restarted
during a snap refresh through the refresh-mode option. The available options
to configure are: restart , endure, (do not restart) or ignore-running
(does not refresh running services to facilitate the refresh app awareness feature)
This test refreshes the test-snapd-service snap and checks the service
test-snapd-endure-service which is configured with 'refresh-mode: endure'
is not restarted during the refresh (keeps the same pid).
