Subject: [PATCH v2 04/16] t2018: use test_expect_code for failing git commands
Date: Mon, 6 Jan 2020 23:53:01 -0500 [thread overview]
Message-ID: <587e53053f02ad0867dc903688c8887602950bd3.1578372682.git.liu.denton@gmail.com> (raw)
In-Reply-To: <cover.1578372682.git.liu.denton@gmail.com>
When we are expecting `git diff` to fail, we negate its status with
`!`. However, if git ever exits unexpectedly, say due to a segfault, we
would not be able to tell the difference between that and a controlled
failure. Use `test_expect_code 1 git diff` instead so that if an
unexpected failure occurs, we can catch it.
We have some instances of `test_must_fail test_dirty_{un,}mergable`.
However, `test_must_fail` should only be used on git commands. Convert
these instances to use the `test_dirty_{un,}mergeable_discards_changes`
helper functions so that we remove the double-negation.
While we're at it, remove redirections to /dev/null since output is
silenced when running without `-v` anyway.
