Quality Engineering

See this wiki for the full list of Quality goals. What follows are our brief summary of our internal improvement goals for each strategic team.

  • Firefox QA - Revitalize our Quality Engineering strategy by switching to a feature-based test strategy for all Firefox browser products so that there are test plans for each feature and testing is executed within two sprints of the feature's code landing
  • Firefox OS - Better metrics for quality analysis, provide opportunities for community contribution, and expanding the role of our on-device automation for reporting to Treeherder.
  • Services - Ensure new offerings have 98% uptime (FxA Sync, OAuth, FMD, Loop) and no more than 2 P1 bugs discovered post launch while building a core contributor base in services
  • Marketplace - Ensure Marketplace's new payments backend, in-app payments, and the Marketplace feed land with high quality releases.
  • Platform QA - Deploy into continuous integration a regression testing system for WebRTC along three areas of investigation: 1. "Smoke" tests, 2. Connection tests, and 3. Connection quality tests. These will be performed in a variety of environments, including various network topologies with various performance characteristics, connections between various versions of Firefox, and connections on multiple OS platforms. Test plans will be developed, and we will measure coverage of test plans. Results will be posted and available in Treeherder. We will also build backlog for next Platform Tiger Team tasks.
  • Community - Increase conversion of interested and casual contributors to help them become active contributors with strong ties to the QA community
