+## Expiration of subscriptions removes them test case
+
+This test case validates that expired subscriptions (created explicitly) are removed from all DSS instances.
+To validate this requirement, the subscriptions that were previously created at each DSS instance are modified so that they expire shortly after the modification.

+Do note that they are not queried directly, as it is deemed acceptable for expired subscription that were not explicitly deleted to still be retrievable.
