March 2026: Strengthened test infrastructure and lint integrity for ClipboardHealth/core-utils by delivering a focused test-utility enhancement. Introduced ESLint/Jest assertion helpers for service results (expectToBeFailure and expectToBeSuccess), enabling precise outcome assertions in tests without disabling lint rules. Config updates ensure these helpers are whitelisted in both .oxlintrc.json and packages/eslint-config/src/index.js and are aligned with exports from @clipboard-health/testing-core. This lays the groundwork for more reliable service-layer tests and more maintainable CI. No major bug fixes were completed this month; the primary value came from improving testing discipline, lint compliance, and cross-repo consistency, which supports faster delivery of robust features in the future.
