Last week’s autopkgtest 3.5 release (in Debian sid and Ubuntu Utopic) brings several new features which I’d like to announce.
Tests that reboot
For testing low-level packages like init or the kernel it is sometimes desirable to reboot the testbed in the middle of a test. For example, I added a new boot_and_services systemd autopkgtest which configures grub to boot with systemd as pid 1, reboots, and then checks that the most important services like lightdm, D-BUS, NetworkManager, and cron come up as expected. (This test will be expanded a lot in the future to cover other areas like the journal, logind, etc.)
In a testbed which supports rebooting (currently only QEMU) your test will now find an “autopkgtest-reboot” command which the test calls with an arbitrary “marker” string. autopkgtest will then reboot the testbed, save/restore any files it needs to (like the tests file tree or previously created artifacts), and then re-run the test with
The new “Reboot during a test” section in README.package-tests explains this in detail with an example.
Implicit test metadata for similar packages
The Debian pkg-perl team recently discussed how to add package tests to the ~ 3.000 Perl packages. For most of these the test metadata looks pretty much the same, so they created a new pkg-perl-autopkgtest package which centralizes the logic. autopkgtest 3.5 now supports an implicit
debian/tests/control control file to avoid having to modify several thousand packages with exactly the same file.
An initial run already looked quite promising, 65% of the packages pass their tests. There will be a few iterations to identify common failures and fix those in
There is still some discussion about how implicit test control files go together with the DEP-8 specification, as other runners like
sadt do not support them yet. Most probably we’ll declare those packages
XS-Testsuite: autopkgtest-pkg-perl instead of the usual
In the same vein, Debian’s Ruby maintainer (Antonio Terceiro) added implicit test control support for Ruby packages. We haven’t done a mass test run with those yet, but their structure will probably look very similar.
