Month: 2025-09 — Vitest core: Delivered feature to display user-provided messages in custom assertion matchers, improving failure clarity and debugging efficiency. The change enables expect.extend to pass custom error messages through to failing assertions, so the user-provided message appears instead of the default matcher text. Primary work anchored by commit 969456b4ac37f8f8fee62c05fc9115b1434d7653 (fix: custom expect messages for `expect.extend` matchers (#8520)). Impact: clearer test failures, faster triage, and better alignment with user expectations for custom matchers. Skills/tech: JavaScript/TypeScript, testing utilities, incremental feature delivery, robust code review, CI integration.
