Reliability, Standards & Testing
Our Reliability, Standards & Testing team (RST) actively participates at Ecma International, the W3C, and the WHATWG, developing new standards and advocating for inclusive workflows. We work on projects with browser implementers and embedders to improve web platform interoperability through specification authoring, shared test suites development and infrastructure maintenance. We use our experience consuming new web platform features to inform our work on web platform reliability.
