Subject: [PATCH v4 08/14] t5520: replace test -{n,z} with test-lib functions
Date: Thu, 7 Nov 2019 10:51:36 -0800
Message-ID: <f31142c6834c74931dfe0e353f696c354584938c.1573152599.git.liu.denton@gmail.com> (raw)
In-Reply-To: <cover.1573152598.git.liu.denton@gmail.com>

When wrapping a Git command in a subshell within another command, we
throw away the Git command's exit code. In case the Git command fails,
we would like to know about it rather than the failure being silent.
Extract Git commands so that their exit codes are not lost.

Instead of using `test -n` or `test -z`, replace them respectively with
invocations of test_file_not_empty() and test_must_be_empty() so that we
get better debugging information in the case of a failure.
