summary: Checks for parallel installation of sideloaded snaps containing desktop applications
details: |
Snapd allows installation of the same snap more than once by combining the
same snap name with different values of an instance key.
One aspect of the instance system is that applications with desktop files
need a mechanism to alter each desktop file so that each instance can be
individually found and started in the desktop shell.
The test installs a snap with a desktop file and looks at the contents of
the instance-aware desktop file written by snapd, to ensure that in each
case the launched application is correct, and that some attributes contain
the name of the instance.
The test also checks that removal of one instance does not affect the
desktop files of other instances, for example by careless use of a glob
pattern to remove generated files.
