Subject: serve_stale: add test with NS timeout
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=refs%2Fmerge-requests%2F1227%2Fhead;p=thirdparty%2Fknot-resolver.git

serve_stale: add test with NS timeout

Modify the test to simulate a non-responsive auth as well. As of v5.4.2,
this test should fail, because serve_stale doesn't work with the current
server selection algorithm.
