Subject: [RFC v3 17/19] of: unittest: migrate tests to run on KUnit
Date: Wed, 28 Nov 2018 11:36:34 -0800
Message-ID: <20181128193636.254378-18-brendanhiggins@google.com> (raw)
In-Reply-To: <20181128193636.254378-1-brendanhiggins-hpIqsD4AKlfQT0dZR+AlfA@public.gmane.org>

Migrate tests without any cleanup, or modifying test logic in anyway to
run under KUnit using the KUnit expectation and assertion API.

Signed-off-by: Brendan Higgins <brendanhiggins-hpIqsD4AKlfQT0dZR+AlfA@public.gmane.org>
