Subject: [PATCH 6/7] t/t3437: update the tests
Date: Sun,  7 Feb 2021 23:44:39 +0530	[thread overview]
Message-ID: <20210207181439.1178-7-charvi077@gmail.com> (raw)
In-Reply-To: <20210207181439.1178-1-charvi077@gmail.com>

Let's do the changes listed below to make tests more easier to follow :

-Remove the dependency of 'expected-message' file from earlier tests to
make it easier to run tests selectively with '--run' or 'GIT_SKIP_TESTS'.

-Add author timestamp to check that the author date of fixed up commit
is unchanged.

-Simplify the test_commit_message() and add comments before the
function.

-Clarify the working of 'fixup -c' with "amend!" in the test-description.

-Remove unnecessary curly braces and use the named commits in the
tests so that they will still refer to the same commit if the setup
gets changed in the future whereas 'branch~2' will change which commit
it points to.
