Hi,

for adduser (which is Priority: important and installed on nearly every
Debian system alive), I would like to use ucf to manage adduser.conf in
the future. I would not like to add ucf as a dependency though.

I am therefore planning to use ucf in Recommends or Suggests and to
scaffold the ucf calls in postinst, providing only very basic conffile
handling in the case where ucf is not installed (leaving that decision
to the local admin).

But due to the criticality of the package, I need to test package
installation in both cases, with and without ucf. This is especially
important because the case "no ucf" might occur in automated settings
like the installer, debootstrap, image and testbed building and breakage
in those functions is likely to do horrible things to Debian's tooling.

How would I do that in autopkgtest? Can I uninstall and reinstall the
package in question while an autopkgtest is running?

I would like to hear about your experiences. Pointers to packages that
are already doing this would be greatly appreciated as well. Thank you
very much.

Greetings
Marc

Sure

I would like to hear about your experiences. Pointers to packages that

You can look at dh-runit, probably not the best example but it gives
you the idea

Sounds like you want the breaks-testbed and needs-root restrictions:

So a testbed has apt configured in a way that apt-get install $PACKAGE
will install _this_ version of the package? Or will it just pull the
version from the archive?

The challenge I have encountered is getting the installed binary; it
seems that it puts files under /tmp/autopkgtest.XXXXX, but cleans it up
before the actual tests run? (I have added a test which searches for
the package during the test run, to no avail.)

We could always use dpkg-repack I suppose, but we would have to do so
before any configuration was modified..

Cheers,
Matt

Actually, disregard this, I neglected to attempt the simple solution:

autopkgtest adds it's own sources.list entry under /tmp, so afaict
'apt-get --reinstall' will do exactly what it should.

Thanks for finding that out. Is there also a documented way to install

Not that I'm aware of, but - there is a fairly standard way of adding
to sources.list.d, so that 'apt install adduser=stable' might be made
to work; otoh it might be dependency hell (less so perhaps in this
particular case).

If you want to test unstable's tests against stable's version I'd maybe
try:

git checkout 3.121
git checkout master -- debian/tests/
autopkgtest -- <etc>

But I might be misunderstanding what you want to do..

Cheers,
Matt

Then this maybe is the point where I need to take a closer look at
piuparts. I hope it can be parametrized. What I want to do is probably something that our tools don't have built-in checks, I'd like to
_remove_ debconf support from a package and make a formerly
debconf/postinst controlled file a dpkg-conffile, and I of course need
to test a number of combinations including changed conffile, deleted
conffile etc foo.
