eslint-plugin-jest-extended

ESLint plugin providing rules for Jest Extended matchers, version 3.0.1 (latest stable). Released under the jest-community organization, this plugin offers rules like prefer-to-be-true, prefer-to-be-false, prefer-to-be-array, prefer-to-be-object, and prefer-to-have-been-called-once, all auto-fixable. It supports ESLint 7/8/9, Node >=16.10, and flat config. Differentiates from eslint-plugin-jest by focusing on jest-extended matchers rather than general Jest best practices. Release cadence: occasional major/minor updates with breaking changes tied to Node and ESLint version support.
