Revision 322c73366a9198d5bd6be08e91b729c775761821 authored by Diane Gallois-Wong on 31 August 2022, 15:57:02 UTC, committed by Marge Bot on 06 September 2022, 08:21:04 UTC
Notably, remove plugin tests on 1M, since the plugin is no longer responsible for enforcing 1M. Similar tests on 1M already exist in tezt, and will be extended in the next commit to cover all the cases of the removed tests.
