summary: Ensure that the location-control interface works.
details: |
The location-control interface allows a snap to operate as the location
service.
A snap which defines the location-control plug must be shown in the
interfaces list. The plug must not be auto-connected on install and, as
usual, must be able to be reconnected.
The snap is also declaring a plug on this interface must be able to ask for
its properties.
# s390x does not support locationd
systems:
- -amazon-linux-2-* # no session services
- -ubuntu-*-s390x # no support for locationd
- -ubuntu-14.04-* # no tests.session support
- -ubuntu-core-* # no session services (except for core20+)
prepare: |
echo "Given a snap declaring a plug on the location-control interface is installed"
snap install test-snapd-location-control-provider
echo "And the provider dbus loop is started"
# XXX: The provider is not a service so we have to start it manually. It
# attaches to the system bus so it just goes into a systemd service and not
# via tests.session.
