Reactotron is a macOS, Windows, and Linux app for inspecting your React JS and React Native apps. View your application state, show API requests & responses, perform quick performance benchmarks, subscribe to parts of your application state, display messages similar to console.log, track global errors with source-mapped stack traces including saga stack traces! You can dispatch actions like a government-run mind control experiment, hot swap your app's state using Redux or mobx-state-tree, track your sagas, show image overlay in React Native, track your Async Storage in React Native, etc. ...

A dead simple library to screenshot test React components. Under the hood, we start a local server that renders components server-side. Each component is given its own dedicated page (e.g. /render/my-component). Then we use Puppeteer to take a screenshot of that page. If you work on a team where developers use a different OS (e.g. Mac OS and Linux), or if you develop on Mac OS but use Linux for continuous integration, you would quickly run into issues where screenshots are inconsistent...

Happo is a visual regression testing tool. It hooks into your CI environment to compare the visual appearance of UI components before and after a change. Screenshots are taken in different browsers and across different screen sizes to ensure consistent cross-browser and responsive styling of your application. The first thing you want to do is to set up a test suite for Happo. A test suite consists of a set of components and variants of those components. There are many ways to do this, and it...

The Snapshot testing approach is really awesome but it has one downside: it cannot be used to make visual regression tests of your components. Thanks to the Puppeteer API it's now possible to use the Chromium browser in...
