Subject: [PATCH 6/7] object tests: add test for unexpected objects in tags
Date: Mon,  8 Mar 2021 21:04:25 +0100
Message-ID: <20210308200426.21824-7-avarab@gmail.com> (raw)
In-Reply-To: <Pine.LNX.4.21.0506212033590.30848-100000@iabervon.org>

Fix a blind spot in the tests added in 0616617c7e1 (t: introduce tests
for unexpected object types, 2019-04-09), there were no meaningful
tests for checking how we reported on finding the incorrect object
type in a tag, i.e. one that broke the "type" promise in the tag
header.
