Subject: [PATCH v5 2/2] t5300: add test for 'show-index --object-format'
Message-ID: <20241104192958.64310-3-abhijeet.nkt@gmail.com>
In-Reply-To: <20241104192958.64310-1-abhijeet.nkt@gmail.com>

In 88a09a557c (builtin/show-index: provide options to determine hash
algo), the flag --object-format was added to show-index builtin as a way
to provide a hash algorithm explicitly. However, we do not have tests in
place for that functionality. Add them.
