**expect-even-more-jest** is a Jest extension that builds on the existing *expect-more-jest* library, adding a collection of additional, opinionated matchers for easier, more readable unit tests. It provides syntactic sugar for constructors, existence checks, deep‑object intersections, mock/spies, promise handling, filesystem assertions, and collection utilities—targeted at JavaScript/TypeScript developers who want richer, expressive assertions in their Jest test suites.
