The branch main has been updated by melifaro: URL: https://cgit.FreeBSD.org/src/commit/?id=513ce835b55831d343185e03a51efa2901405ac8 commit 513ce835b55831d343185e03a51efa2901405ac8 Author: Alexander V. Chernikov <melifaro@FreeBSD.org> AuthorDate: 2022-06-28 10:49:41 +0000 Commit: Alexander V. Chernikov <melifaro@FreeBSD.org> CommitDate: 2022-06-28 12:20:16 +0000 testing: pass ATF vars to pytest via env instead of arguments. This change is a continuation of 9c42645a1e4d workaround. Apparently pytest argument parser is not happy when parsing values with spaces or just more than one --atf-var argument. Switch wrapper to send these kv pairs as env variables. Specifically, use _ATF_VAR_key=value format to distinguish from the other vars. Add the `atf_vars` fixture returning all passed kv pairs as a dict.
