[11:44:01] <zeljkof>	 We regularly run destructive tests on the beta cluster, creating pages and users, changing them, deleting them...
[11:44:12] <zeljkof>	 I guess it would be similar with functions
[11:45:09] <zeljkof>	 the convention is that each tests doesn't assume anything (except a wiki with a main page and an admin user) is there, so if the test needs users, pages, functions (...) it creates them in a setup step.
[11:45:45] <zeljkof>	 We usually don't clean up after the test, leaving a lot of randomly named users and pages around, by we don't care about that in the beta cluster (or CI)
[11:46:14] <zeljkof>	 But there's always a possibility of cleaning up after the test in a teardown step/hook.
