Subject: [PATCH v2 01/16] test-lib-functions: introduce test_non_git_might_fail()
Date: Thu, 19 Dec 2019 14:22:36 -0800
Message-ID: <85cee927656cebed34bc93280d0b2d89e0caa570.1576794144.git.liu.denton@gmail.com> (raw)
In-Reply-To: <cover.1576794144.git.liu.denton@gmail.com>

In a future commit, we will be preventing the use of the
test_must_fail()-family of functions (including test_might_fail()) on
non-git comands. To prep for this, introduce the
test_non_git_might_fail() function which is used to replace non-git
invocations of test_might_fail().

The test_non_git_might_fail() function is a lightweight replacement,
always masking the return status of the command and returning a
non-error exit code. Unlike test_might_fail(), it does not check for
abnormal exit conditions such as a segv. This is because we are not in
the business of checking the sanity of the external environment and we
can assume that it works properly.
