Subject: [PATCH v5 3/3] t6402: preserve git exit status code
Date: Sun,  4 Jul 2021 12:46:12 +0700	[thread overview]
Message-ID: <f8ed19f858283e18ff4ae2d6ece199c82b624c30.1625362489.git.congdanhqx@gmail.com> (raw)
In-Reply-To: <cover.1625362488.git.congdanhqx@gmail.com>

In t6402, we're checking number of files in the index and the working
tree by piping the output of Git's command to "wc -l", thus losing the
exit status code of git.

Let's use the new helper test_stdout_line_count in order to preserve
Git's exit status code.
