From Automation and Tools to Engineering Productivity
“Automation and Tools” has been our name for a long time, but it is a catch-all name which can mean anything, everything, or nothing, depending on the context. Furthermore, it’s often unclear to others which “Automation” we should own or help with.
For these reasons, we are adopting the name “Engineering Productivity”. This name embodies the diverse range of work we do, reinforces our mission (https://wiki.mozilla.org/Auto-tools#Our_Mission), promotes immediate recognition of the value we provide to the organization, and encourages a re-commitment to the reason this team was originally created—to help developers move faster and be more effective through automation.
The “A-Team” nickname will very much still live on, even though our official name no longer begins with an “A”; the “get it done” spirit associated with that nickname remains a core part of our identity and culture, so you’ll still find us in #ateam, brainstorming and implementing ways to make the lives of Mozilla’s developers better.
Treeherder: Most of the backend work to support automatic starring of intermittent failures has been done. On the front end, several features were added to make it easier for sheriffs and others to retrigger jobs to assist with bisection: the ability to fill in all missing jobs for a particular push, the ability to trigger Talos jobs N times, the ability to backfill all the coalesced jobs of a specific type, and the ability to retrigger all pinned jobs. These changes should make bug hunting much easier. Several improvements were made to the Logviewer as well, which should increase its usefulness.
Perfherder and performance testing: Lots of Perfherder improvements have landed in the last couple of weeks. See details at wlach’s blog post. Meanwhile, lots of Talos cleanup is underway in preparation for moving it into the tree.
MozReview: Some upcoming auth changes are explained in mcote’s blog post.
Mobile automation: gbrown has converted a set of robocop tests to the newly enabled mochitest-chrome on Android. This is a much more efficient harness and converting just 20 tests has resulted in a reduction of 30 minutes of machine time per push.
Developer workflow: chmanchester is working on building annotations into moz.build files that will automatically select or prioritize tests based on files changed in a commit. See his blog post for more details. Meanwhile, armenzg and adusca have implemented an initial version of a Try Extender app, which allows people to add more jobs on an existing try push. Additional improvements for this are planned.
Firefox automation: whimboo has written a Q2 Firefox Automation Report detailing recent work on Firefox Update and UI tests. Maja has improved the integration of Firefox media tests with Treeherder so that they now officially support all the Tier 2 job requirements.
WebDriver and Marionette: WebDriver is now officially a living standard. Congratulations to David Burns, Andreas Tolfsen, and James Graham who have contributed to this standard. dburns has created some documentation which describes which WebDriver endpoints are implemented in Marionette.
Version control: The ability to read and extra metadata from moz.build files has been added to hg.mozilla.org. This opens the door to cool future features, like the ability auto file bugs in the proper component and automatically selecting appropriate reviewers when pushing to MozReview. gps has also blogged about some operational changes to hg.mozilla.org which enables easier end-to-end testing of new features, among other things.
