The purpose of this test case is to ensure USS validation
Where .snaps folder is only readable and listing all the snapshots and it's content. Also ensures that deactivated snapshot doesn't get listed. Change-Id: I25ad451986c861038450c0369e6cbc130b8945bb Signed-off-by: vivek das <vdas@redhat.com> Signed-off-by: srivickynesh <sselvan@redhat.com>
