PROFILE
Dasaria
Over two months, Dasaria enhanced the tc39/test262 repository by building foundational and comprehensive test coverage for the experimental Promise.allKeyed and Promise.allSettledKeyed features. Using JavaScript and ES6, Dasaria established robust test scaffolding, introduced feature flags to safely gate experimental tests, and modernized the async test framework for reliability. The work included validating extensibility, property exposure, and key ordering, as well as expanding coverage to functions, BigInt, and symbol keys. By aligning tests with Reflect.ownKeys and refining error handling, Dasaria ensured spec adherence and future-proofed the test suite, demonstrating depth in async programming and testing methodologies.

Apr 1, 2026April 2026: Delivered a major upgrade to the tc39/test262 Promise utilities tests, delivering comprehensive coverage for Promise.allKeyed and Promise.allSettledKeyed, including functions, BigInt, symbol keys, and prototype properties. Modernized the async test framework (asyncTest, assert.throwsAsync) for improved reliability. Strengthened test validation by aligning key checks with Reflect.ownKeys and implementing deterministic settlement ordering. Enabled targeted BigInt tests behind the feature flag and expanded coverage of non-enumerable and symbol-key scenarios, ensuring spec-adherence and future-proofing against changes.

Feb 1, 2026February 2026: Established foundational test scaffolding and baseline coverage for the Await Dictionary feature in tc39/test262, enabling safe experimentation and progress toward standardization. Delivered initial boilerplate tests for Promise.allKeyed and Promise.allSettledKeyed, gated behind a feature flag to prevent regressions and accelerate validation while maintaining current releases.
