Subject: [PATCH 5/6] auto-t: add two tests for new FT behavior
Date: Wed, 5 Oct 2022 15:46:31 -0700 [thread overview]
Message-ID: <20221005224632.780575-5-prestwoj@gmail.com> (raw)
In-Reply-To: <20221005224632.780575-1-prestwoj@gmail.com>
These tests ensure proper behavior if FT fails to authenticate
