Notices, Highlights, Roundtable

• 1/3 of the way through the quarter. Any goals in trouble?
• [bc] I'd like to discuss some ideas for statistical methods for obtaining reliable performance measurements.
  • Background discussion bug 866195 Improve Autophone s1s2 test reproducibility
  • Using mean and standard error of the mean rather than mean and standard deviation of measurements.
  • Choosing number of measurements and a target percentage standard error of the mean.
  • Rejecting and re-testing measurements with overly large percentage standard error of the mean.
  • Filtering outliers using quartiles: http://en.wikipedia.org/wiki/Interquartile_range
  • Choosing a device settling time before starting tests.

Goals

• Goal: Improve Developer/QA ergonomics around running and debugging automation by:
  • Add debugger support to B2G testrunners
  • Improve patch review experience on bugzilla/Make bugzilla more user-centric
  • Replace graph server with Datazilla for all desktop Talos tests
  • Create a project branch view of B2G builds/tests that tracks commits per target, rather than per repo (all commits to any repo for unagi for instance) joint with releng

• Goal: Improve stability, reliability, and scalability of automation platforms by:
  • Addressing all P1 B2G automation stability issues
  • Complete native REST interface for Bugzilla
  • Complete Mochitest to Mozbase port
  • Create POC Microbenchmark suite to get feedback from developers for its usefulness
  • Reduce orange factor to 5 or lower (for the last three weeks of the quarter) by driving awareness among developers, following up with assignees, and fixing intermittent automation failures.
  • Update pulse so that its dependent (client side) libraries are current for its use in Tree Herder
  • Create a prototype and a specification for a rig to power cycle real phones. Have a vendor selected to build the rig by end of quarter.

• Goal: Build toward our future by:
  • Deploy a minimally viable TBPL replacement by end of quarter, aim to switch over mid-Q3
  • Release a mozmill 2 and work with contributor community to drive toward a 2.1
  • Automate a scrolling fps test using camera Eideticker measurements for Contacts, Email, Settings, and Message apps
  • Create and Deploy BMO user profile data for community building and education
  • Create a solid net and filter system to build a bugmaster community
  • Identify 5 things we can do to increase our infrastructure capacity by 10% through more streamlined usage and bringing new capacity online. (joint with releng)
  • Enable performance and test automation to run on Android x86 hardware, investigate Android 2.3.x support on Pandas.
