summary: Check that the basic snapshots functionality works for different users
details: |
This test checks that the basic snapshots functionality works for different
users. It runs through a series of operations that create, restore, and
remove snapshots for both the root and test users.
# ubuntu-14.04: the test sets up a user session, which requires more recent systemd
systems: [-ubuntu-14.04-*]
prepare: |
snap install test-snapd-sh
tests.session -u test prepare
restore: |
tests.session -u test restore
execute: |
# use the snaps, so they create the dirs
test-snapd-sh.sh -c 'true'
SNAP_MOUNT_DIR="$(os.paths snap-mount-dir)"
tests.session -u test exec sh -c "$SNAP_MOUNT_DIR/bin/test-snapd-sh.sh -c 'true'" test
