    When true, tempest cleanup creates a report (./dry_run.json) of the
    resources that would be cleaned up if the role was ran with dry_run option
    set to false.

+.. zuul:rolevar:: run_tempest_fail_if_leaked_resources
+   :default: false
+
+   When true, the role will fail if any leaked resources are detected.
+   The detection is done via dry_run.json file which if contains any resources,
+   some must have been leaked. This can be also used to verify that tempest
+   cleanup was successful.
+
+
+Role usage
+----------
+
+The role can be also used for verification that tempest tests don't leak any
+resources or to test that 'tempest cleanup' command deleted all leaked
+resources as expected.
+Either way the role needs to be run first with init_saved_state variable set
+to true prior any tempest tests got executed.
+Then, after tempest tests got executed this role needs to be run again with
+role variables set according to the desired outcome:
+
+1. to verify that tempest tests don't leak any resources
+   run_tempest_dry_cleanup and run_tempest_fail_if_leaked_resources have to
+   be set to true.
+
+2. to check that 'tempest cleanup' command deleted all the leaked resources
+   run_tempest_cleanup and run_tempest_fail_if_leaked_resources have to be set
+   to true.
