summary: Checks for parallel installation of a local snap files
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 installs a snap twice, and inspects that the applications can be
invoked separately, obtain tailored environment variables which are aware of
the difference in the instance key, read and write data to separate
directories and that while the directories to not always show up as the
instance-key-aware names on the inside of the snap execution environment, on
the outside the names are indeed correct and do contain the instance key. In
other words, the two applications are separate and have separate state.
# ubuntu-14.04: the test sets up a user session, which requires more recent systemd
systems: [-ubuntu-14.04-*]

# ensure we have no snap user data directory yet
