Subject: [PATCH v2] tests: move t0009-prio-queue.sh to the new unit testing framework
Date: Sun, 14 Jan 2024 08:18:24 +0000 [thread overview]
Message-ID: <pull.1642.v2.git.1705220304781.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.1642.git.1705219829965.gitgitgadget@gmail.com>
From: Chandra Pratap <chandrapratap3519@gmail.com>
t/t0009-prio-queue.sh along with t/helper/test-prio-queue.c unit
tests Git's implementation of a priority queue. Migrate the
test over to the new unit testing framework to simplify debugging
and reduce test run-time. Refactor the required logic and add
a new test case in addition to porting over the original ones in
shell.
