summary: Test the auto-connect behavior of the cups-control interface.
details: |
The cups-control interface is provided as an implicit slot on classic
systems. It is also provided as a slot by the cups snap. Normally snapd will
not auto-connect a plug if there are multiple candidate slots available.
However the cups-control interface is set up to only make one slot a
candidate: if a non-snap cupsd appears to be on the system then
system:cups-control is favoured. And if there is no non-snap cupsd, the
reverse is true.
systems:
- -ubuntu-core-*
- -ubuntu-14.04*

BLOB_DIR: $(pwd)/fake-store-blobdir
