lddubeau/expect-rejection

A tiny TypeScript/JavaScript helper that lets you assert that a promise rejects without writing repetitive boilerplate. By calling `use(chai)` once and then `expectRejection(...)` in your tests, you can cleanly verify promise rejections while using plain Chai (no need for chai‑as‑promised or a full plugin). It’s aimed at developers who write unit tests with async/await and want a minimal, personal‑use solution for rejection testing.
