summary: Checks for parallel installation of snaps from the store
details: |
Snapd allows installation of the same snap more than once by combining the
same snap name with different values of an instance key.
The test checks that snapd can successfully install snaps, as parallel
instances, from the snap store, to ensure that the store is not confused by
the presence of the instance key.
