# asyncFn

![Build and test](https://github.com/team-igniter-from-houston-inc/async-fn/workflows/Build%20and%20test/badge.svg) [![Gitter](https://badges.gitter.im/async-fn/community.svg)](https://gitter.im/async-fn/community?utm_source=badge&utm_medium=badge&utm_campaign=pr-badge)

**[asyncFn](https://github.com/team-igniter-from-houston-inc/async-fn)** is a library that provides additional methods to [jest.fn](https://www.npmjs.com/package/@async-fn/jest) or [sinon.spy](https://www.npmjs.com/package/@async-fn/sinon) to introduce "**late resolve**" for the promises returned.

This simplifies async unit testing by allowing tests that read chronologically, **[like a story](https://medium.com/houston-io/how-to-unit-test-asynchronous-code-for-javascript-in-2020-41c124be2552)**.

asyncFn has zero non-native dependencies. It has **100% unit test coverage**, and 3+ years of focused **production use** with high **developer satisfaction**.

asyncFn is also **integration-tested** for combinations of recent OS-, node- and mocking framework -versions.
