PROFILE
Alexander Cooper
Al Cooper developed and stabilized WebXR Android test execution infrastructure for the denoland/chromium_build repository, focusing on end-to-end test coverage and CI reliability. He integrated a mock OpenXR runtime and updated the test harness to automate runtime preparation, addressing flaky failures by deploying the runtime to a system-writable location. Using Python scripting, Android development, and system integration skills, Al also improved test resource accuracy by introducing a dedicated test APK for OpenXR runtime deployment. His work ensured correct test support resources were used, reducing flakiness and enhancing traceability, while balancing the tradeoff between local development speed and robust CI results.

Jan 1, 2025January 2025: Implemented WebXR Android test execution infrastructure and stabilized OpenXR Android tests for denoland/chromium_build, delivering end-to-end WebXR coverage on Android and more reliable CI results. The work added a mock OpenXR runtime and integrated runtime preparation into the test flow (commit 03ff285e13356633bd28ea1187e74b0e0c113441), and deployed the runtime to a system-writable location to prevent wipes to address flaky tests (commit 13c883f879cc533a53fb4961c9d3ad95a75079f3). This expanded test coverage, reduced flaky failures, and strengthened Android WebXR support. Technical focus included Android test automation, OpenXR, mock runtimes, and test harness updates. Note: local development may be slower due to the runtime deployment strategy.
