Subject: [PATCH 04/10] test-lib.sh: add a --invert-exit-code switch
Date: Tue, 19 Jul 2022 23:05:18 +0200	[thread overview]
Message-ID: <patch-04.10-4aab7af60e3-20220719T205710Z-avarab@gmail.com> (raw)
In-Reply-To: <cover-00.10-00000000000-20220719T205710Z-avarab@gmail.com>

Add the ability to have those tests that fail return 0, and those
tests that succeed return 1. This is useful e.g. to run "--stress"
tests on tests that fail 99% of the time on some setup, i.e. to smoke
out the flaky run which yielded success.

In a subsequent commit a new SANITIZE=leak mode will make use of this.
