The resulting XML files are stored here: https://github.com/gluster/glusterfs-patch-acceptance-tests/tree/master/jenkins/jobs > 2. How are the machines created? Do we have a standardized image? No idea, Micheal Scherer should know. I guess Manu setup the NetBSD systems, not sure who takes care of the FreeBSD ones. > 3. Where is the code (the repository) for the tests that are run? Most of the tests have their scripts in the patch-acceptance-test repository: https://github.com/gluster/glusterfs-patch-acceptance-tests The regression tests themselves are contained in the glusterfs repository. We expect that all changes to the sources come with a test-case. > 4. What is the process for going from updating the code for a test to > updating the job on Jenkins? Is this automated and/or documented? Not sure. The number of people that modify the Jenkins jobs is very small. All of them are aware (or should be!) that a modification requires updating the XML files in the git repo. > 5. How many of the jobs are critical? All of the regular running ones? > 6. What is the process for creating new jobs/new types of tests? That is hardly ever needed, and more of an exception. If someone needs a new job on build.gluster.org one of the people with an account can create it. > Bonus Question: Is there any friction that you'd like to see us reduce? One of the things we're doing for this is to move more time consuming and multi-host tests to ci.centos.org. Currently the regression tests are still running on our own instance, but the CentOS CI has much more and much faster hardware (no VMs). There is the long-term plan to move at least a bunch of the heavy testing to their Jenkins instance. Also scheduled jobs (distaf tests, tests for integration with other projects, nightly builds, ....) are supposed to get added to the CentOS CI, and not our build.gluster.org environment: https://ci.centos.org/view/Gluster/ Thanks, Niels
