[Pkg-javascript-devel] Bug#1117570: nodejs: flaky autopkgtest: multiple failure modes

[Paul Gevers]

Source: nodejs
Version: 20.19.4+dfsg-1
Severity: serious
User: debian-ci at lists.debian.org
Usertags: flaky

Dear maintainer(s),

I looked at the results of the autopkgtest of your package because it 
showed up as a regression for node-undici on ppc64el. I noticed that it 
regularly fails (at least on amd64 and ppc64el). I saw at least two 
failure modes, see below.

Because the unstable-to-testing migration software now blocks on
regressions in testing, flaky tests, i.e. tests that flip between
passing and failing without changes to the list of installed packages,
are causing people unrelated to your package to spend time on these
tests.

Don't hesitate to reach out if you need help and some more information
from our infrastructure.

Paul
