Subject: [PATCH v9 4/9] t3432: test for --no-ff's interaction with fast-forward
Date: Sun, 25 Aug 2019 05:12:05 -0400	[thread overview]
Message-ID: <48b4e41a17d98b2f3a4254ed37c76361c3abc9ba.1566724236.git.liu.denton@gmail.com> (raw)
In-Reply-To: <cover.1566724236.git.liu.denton@gmail.com>

From: Ævar Arnfjörð Bjarmason <avarab@gmail.com>

Add more stress tests for the can_fast_forward() case in
rebase.c. These tests are getting rather verbose, but now we can see
under --ff and --no-ff whether we skip work, or whether we're forced
to run the rebase.

These tests aren't supposed to endorse the status quo, just test for
what we're currently doing.
