Jun 1, 2025Month: 2025-06 — Performance review for aws/amazon-chime-sdk-js focusing on CI and test reliability improvements. Delivered browser-compatibility testing support in CI by updating the setup-integration-test action and reusing the same setup logic in the browser-compatibility-test workflow. Implemented backwards-compatibility testing adjustments and fixed test stability issues to reduce false positives. Addressed daily test failures linked to a new dependency by adding the necessary dependency. Result: broader cross-browser coverage, more stable CI, and faster feedback cycles for releases.
