Overview

Chromogen has emerged as a game-changing tool for developers embracing the capabilities of Zustand and Recoil for state management in their React applications.

With its user-friendly interface, it captures state changes during actual user interactions and quickly auto-generates Jest test suites that are ready to be utilized.

This tool is perfect for independent developers or teams that require efficiency without sacrificing quality in their work. Compatibility with React V18 ensures that you can leverage the latest features of React while maintaining robust testing capabilities. With Chromogen, testing becomes a quick and seamless process, providing confidence in your application’s reliability.
