       checkbox_ng - CheckBoxNG Documentation

       CheckBoxNG  is a hardware testing tool useful for certifying laptops, desktops and servers
       with Ubuntu. It is a new version of CheckBox that is built directly on top of PlainBox

       CheckBoxNG replaces CheckBox, where applicable.

          Documentation is under development. Some  things  are  wrong,  inaccurate  or  describe
          development goals rather than current state.


       CheckBoxNG  can be installed from a PPA (recommended) or pypi on Ubuntu Precise (12.04) or

          $ sudo add-apt-repository ppa:checkbox-dev/ppa && sudo apt-get update && sudo apt-get install checkbox-ng


       CheckBoxNG has special support for running stable release updates tests  in  an  automated
       manner.  This  runs  all  the  jobs  from  the  sru.whitelist and sends the results to the
       certification website.

       To run SRU tests you will need to know the so-called Secure  ID  of  the  device  you  are
       testing. Once you know that all you need to do is run:

          $ checkbox sru $secure_id submission.xml

       The  second  argument, submission.xml, is a name of the fallback file that is only created
       when sending the data to the certification website fails to work for any reason.


       Test 'scripts' are small programs which are used to aid in implementing tests.

       This script tests the brightness of the systems backlight can  be  changed  by  using  the
       kernel  interfaces in /sys/class/backlight. There may be more than one interface to choose
       from, so the correct interface to use is selected by using  the  heuristic  prescribed  in  The brightness
       is manipulated by updating the brightness file of the interface and the  actual_brightness
       file is checked to see if the value was modified to the brightness selected.


       This  page  describes  the necessary steps for releasing versions of CheckBox and CheckBox
       Certification to the stable PPA belonging to the Hardware Certification team, on a regular
       basis.  Throughout  this document the term 'CheckBox' is used as a catch-all term to cover
       all versions of CheckBox owned by the  Hardware  Certification  team,  currently  CheckBox
       itself and the CheckBox Certification extensions.

       Currently  the  process  runs on a bi-weekly cadence, with a new release of Checkbox every
       two weeks. This covers ten working days, and the tasks carried out on each day or group of
       days is described below:

       · Days 1-4: Time allowed for new changes to be introduced into trunk.

       · Day 5: Changes are merged from the trunk of lp:checkbox and lp:checkbox-certification to
         their respective release branches.  The changelogs for both are bumped at this point and
         revisions are tagged.  At this stage it may also be necessary to copy the package 'fwts'
         from the FWTS Stable PPA to the Checkbox Release Testing PPA.

       · Days 6-9: Testing is performed by the release manager  for  the  Hardware  Certification
         team,  and  a  representative  of  the CE QA team (the main customer for CheckBox within

       · Day 9: A  release  meeting  is  held  between  the  release  manager  for  the  Hardware
         Certification  team and the representative of the CE QA team.  Potential issues with the
         release are identified and plans made to address them.

       · Day 10: The tested version of CheckBox is copied to the stable PPA.

   Launchpad Branches
       The release process requires separate  branches  in  Launchpad  containing  a  semi-frozen
       version of the code that was in trunk on day 5 of the process. This is so that development
       can continue on trunk without jeopardising the stability of the to-be released version  of
       CheckBox. The relationship between all branches involved in the process is as shown below:

       · lp:checkbox/release <- lp:checkbox

       · lp:checkbox-certification/release <- lp:checkbox-certification

       · lp:~checkbox-dev/checkbox/checkbox-packaging-release                                  <-

   Auditing milestoned bugs
       Prior to creating the release candidate the release manager should review the list of bugs
       milestoned  for  the  next  release of CheckBox. They should visit checkbox milestones and
       locate the milestone dated with the release date.

       · For bugs that are set to In Progress with a branch associated - liase  with  the  branch
         owner to see if the merge can be completed before the deadline.

       · For  bugs  that  are in any other non-closed status (except Fix Commited) - re-milestone
         them to the following milestone.

   Cutting the release
       In order to cut the release, we have to merge the changes  from  trunk  into  the  release
       branch,  commit  them  with  a  suitable message and update the changelog in trunk so that
       future changes go under the correct version. For each combination of branches shown above,
       do the following (the example uses lp:checkbox and lp:checkbox/release):

          bzr branch lp:checkbox/release checkbox-release
          bzr branch lp:checkbox checkbox-trunk
          cd checkbox-release
          current_stable=`head -n1 $(find . -name 'changelog') | grep -oP '(?<=\().*(?=\))'`
          bzr merge lp:checkbox

       at  this point if no changes (other than one to debian/changelog) get merged in then we do
       not perform a release of the package in question. In  practice  this  often  happens  with
       checkbox-certification but never with checkbox:

          bzr commit -m "Merged in changes from rev$(bzr revno -r tag:$current_stable lp:checkbox) to rev$(bzr revno lp:checkbox) from lp:checkbox"
          bzr push lp:checkbox/release
          cd `find . -name 'debian'`; cd ..
          bzr tag `head -n1 debian/changelog | grep -oP '(?<=\().*(?=\))'`
          dch -r (save modified changelog)
          dch -i -U 'Incremented changelog'
          bzr push lp:checkbox

       The   last   step  in  the  process  is  to  perform  a  build  of  the  packages  in  the
       ppa:checkbox-dev/testing PPA. To do this we need  to  go  to  the  recipe  pages  for  the
       checkbox and/or checkbox-certification release branches.

          · checkbox-testing recipe

          · checkbox-certification-testing recipe

       The Build Now option should be available on the page. Click it to start a build.

   Copying Firmware Test Suite to the Testing PPA
       The  Firmware Test Suite tool is a test tool for system firmware that is naturally heavily
       utilised by Checkbox. To make sure  the  latest  version  which  contains  fixes  and  new
       tests/features  needed  by  Checkbox  is  available  and  also  doesn't  break anything in
       Checkbox, we need to release it alongside Checkbox.  After  cutting  the  release  if  the
       Firmware  Testing team have notified that a new version is available and that this version
       should be used for certification, we need to copy it to the Testing PPA.  To  do  this  we
       need  to  go  to the Copy packages view of the Firmware Test Suite (Stable) PPA and select
       the 'fwts' packages for all releases back to Precise. We need to set the 'Destination PPA'
       as  'Checkbox  Release  Testing  [~checkbox-dev/testing]'  and the 'Copy options' field to
       'Copy existing binaries', then click 'Copy packages'. This step then needs to be  repeated
       but set the 'Destination PPA' field to 'PPA for Checkbox Developers [~checkbox-dev/ppa]'.

   Next Release of Checkbox e-mail
       So  that  everyone has the opportunity to perform whatever testing is required in a timely
       manner, after the PPA builds have been completed an email should be sent to the  following
       mailing lists:



       The content is typically something like this:

          Subject: Next Release of CheckBox (18/11/2013)


          The next release of CheckBox is available in the
          Please test it at your convenience. CheckBox is based on revision 2484 of
          lp:checkbox and CheckBox Certification is based on revision 586 of


       If  one  or  the  other  of CheckBox and CheckBox Certification have not been updated then
       there is no need to mention that package

   Testing the release
       Now that the release has been cut, testing should take place prior to the release meeting.
       From  the  point  of  view  of  the  certification  team,  what  needs  to  be  tested  is
       checkbox-certification-client and checkbox-certification-server which form the  basis  for
       CE  QAs  OEM specific versions of CheckBox. CheckBox certification server is tested in the
       CI loop CheckBox certification client needs to be tested manually.

   Release Meeting
       On the Thursday before the release is made, a meeting is held between a representative  of
       the  Certification  team  and  a representative of the Commercial Engineering QA team. The
       meeting is held at 7:30 UTC as shown in this calendar invite.  An agenda for  the  meeting
       is included in the invite.

   Publishing the release
       To  publish  the  release  we  simply  need to copy a number of packages from the Checkbox
       Release Testing PPA to the Hardware Certification Public PPA. To do this we go to the Copy
       packages view of the Checkbox Release Testing PPA and select all versions of the following
       list of packages: checkbox, checkbox-certification, fwts. Make sure that the  'Destination
       PPA'     field     is     set     to    'Public    PPA    for    Hardware    Certification
       [~hardware-certification/public]' and that the  'Copy  options'  field  is  set  to  'Copy
       existing binaries', then click 'Copy Packages'.

       After     that     is    done    an    announcement    email    should    be    sent    to  A template for the announcement  in  included


          A new release of checkbox has been uploaded to the Hardware
          Certification Public PPA
          ( The
          release is based on revision 2294 of lp:checkbox
