TestEngineering/Performance

Objectives

• Increase regression detection coverage to page load on Android products including WebView comparisons
• Increase quality standards by measuring and alerting on power usage for Android and ARM64
• Build dashboards to improve visibility of how we are tracking against our release criteria for Android
• Reducing noise in test results and adding annotations to provide clarity of signal for regressions
• Develop measurements and mechanisms for reporting on our tools, policies and documentation for how to improve clarity and efficiency of risk assessments
