summary: Ensure that the ros-snapd-support interface works.
details: |
The ros-snapd-support interface allows the ros-snapd snap to
control snap applications.
The ros-snapd and ros2-snapd snaps define the ros-snapd-support plug.
The snaps declaring a plug on this interface must be able to control
snap applications through the snapd-snap.socket.
The test snap used has a command to get the list of snap applications
(exercising the read capability on the socket) and a command stop a snap application
(which checks the write capability).
environment:
# Python determines the "encoding" of standard output and it historically chose
# to use 7-bit ascii, breaking everything.
# In this test we pipe the outputs to gojq.
PYTHONIOENCODING: utf-8
