(I posted the message below on the Fedora LiveCD list and it
was suggested that I post the question on this ‘test’ list as
well.) Hello, Has anyone set up a continuous build and automated testing
system for LiveCD development? I am in the process of creating one and
would like to compare notes and discuss approaches. The objective is to
perform regression testing on LiveCDs where all configuration is specified in a
kickstart file. We must be able to capture the boot messages as part of
this testing. I have the continuous build portion working and am now
starting on the automated testing piece. Here is an activity diagram for
the build/test phases (note that the testing phase has not yet been
implemented): http://jaroker.com/EA4.png
(You can ignore the “wake up slave” and “power off
slave”. We have a noisy server dedicated to the build. Since
it is only run 1-2 times per day, the build process turns the server on/off as
needed.) Here is what I am trying to achieve: -
LiveCD is customized via a kickstart file and this
kickstart is committed to SVN -
Build server will connect to a workstation (not a
virtual server due to loopback restrictions) and check out kickstart -
LiveCD scripts are run on the workstation -
Kernel files are created and custom applications are
loaded into the file structure -
ISO image is created -
Qemu is used to boot the ISO image, but where the
console is redirected to a TTY -
An Expect script telnets into Qemu to start the boot
and the Expect script captures boot messages to a text file (We have this
Expect process working and it seems to be stable.) -
Boot messages are analyzed using another script for
errors and warnings -
Selenium grid is used to test the boot disk (running
under Qemu) by simulating user activity to run regression tests on the LiveCD -
If the original kickstart passes all tests, then the
kernel files are committed to SVN as artifacts Please let me know if anyone has experience doing this, or
can recommend simplifications to regression testing. Most importantly,
please tell me if I may have overlooked some existing testing framework for
LiveCDs. I would hate to do this work only to realize that it has already
been done. Thank you, Jon |
