React Native Owl is a visual regression testing library for React Native that enables developers to introduce visual regression tests to their apps for iOS and Android. Being heavily inspired by Detox, an end-to-end testing and automation framework, this library uses a similar API that makes setting up react-native-owl and running the tests locally and on your preferred CI service seamless.

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. ...

...We believe the only way to tackle flakiness head on is by moving from black box testing to gray box testing. That's where Detox comes into play. Detox is built from the ground up to support React Native projects as well as pure native ones. Read the Getting Started Guide to get Detox running on your app in less than 10 minutes. We believe that the only way to address the core difficulties with mobile end-to-end testing is by rethinking some of the principles of the entire approach.

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...

There are a few visual regression tools for the web, but most either cannot be run headless or use phantomjs which is deprecated and a browser nobody is actually using. They usually also require you to maintain fixtures. With react-native it's now possible to target multiple platforms with a single code base, but there's no single tool to test all to my knowledge. Loki aims to have easy setup, no to low maintenance cost, reproducible tests independent of which OS they are run on, runnable on CI, and support all platforms storybook does.

...The library is useful for responsive behavior that depends on screen size, device type, orientation, or other media query conditions. It can be used with a companion addListener polyfill when code needs to react to changes over time. The project was used by tools such as Respond.js, FormFactor, and Modernizr, which reflects its role in older responsive web development workflows. It is most relevant for legacy browser support, educational reference, and projects that need to understand how JavaScript-based media query testing worked before broad native support.
