Reactotron
Desktop app for inspecting your React JS and React Native projects
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. You plug it into your app as a dev dependency so it adds nothing to your product builds. Reactotron, as an open source project, is free to use and always will be. -

Appium
Automation for iOS, Android, and Windows Apps
Appium is an open source test automation framework for use with native, hybrid and mobile web apps. It drives iOS, Android, and Windows apps using the WebDriver protocol. Is native app automation missing from your tool belt? Problem solved.

Appium is an open source project and has made design and tool decisions to encourage a vibrant contributing community. Appium aims to automate any mobile app from any language and any test framework, with full access to back-end APIs and DBs from test code. Write tests with your favorite dev tools using all the above programming languages, and probably more (with the Selenium WebDriver API and language-specific client libraries). -

You can also use it within the browser; install via npm and use the chai.js file found within the download. Browse our growing directory of custom plugins & vendor integrations to find the best tool for your needs. Chai has an extensive utility belt for plugin developers. Learn how to build your plugins & share. -

redux-saga
An alternative side effect model library for Redux applications
redux-saga is a library that aims to make application side effects (i.e. asynchronous things like data fetching and impure things like accessing the browser cache) easier to manage, more efficient to execute, easy to test, and better at handling failures. The mental model is that a saga is like a separate thread in your application that's solely responsible for side effects. redux-saga is a redux middleware, which means this thread can be started, paused and cancelled from the main application with normal redux actions, it has access to the full redux application state and it can dispatch redux actions as well. It uses an ES6 feature called Generators to make those asynchronous flows easy to read, write and test. (if you're not familiar with them here are some introductory links) By doing so, these asynchronous flows look like your standard synchronous JavaScript code. (kind of like async/await, but generators have a few more awesome features we need). -

Karma
Test Runner for JavaScript
The main goal for Karma is to bring a productive testing environment to developers. The environment being one where they don't have to set up loads of configurations, but rather a place where developers can just write the code and get instant feedback from their tests. Because getting quick feedback is what makes you productive and creative. Test your code on real browsers and real devices such as phones, tablets or on a headless PhantomJS instance. Control the whole workflow from the command line or your IDE - just save a file and Karma will run all the tests. Describe your tests with Jasmine, Mocha, QUnit, or write a simple adapter for any framework you like. Developed for and maintained by the open source community at GitHub. Easy debugging directly from your IDE via WebStorm or Google Chrome. Simple integration with Jenkins, Travis or Semaphore. -

Mocha
A feature-rich JavaScript test framework running on Node.js
Mocha is a feature-rich JavaScript test framework running on Node.js and in the browser, making asynchronous testing simple and fun. Mocha tests run serially, allowing for flexible and accurate reporting, while mapping uncaught exceptions to the correct test cases. Hosted on GitHub. Mocha runs in the browser. Every release of Mocha will have new builds of ./mocha.js and ./mocha.css for use in the browser. Mocha is the most-depended-upon module on npm and Mocha is an independent open-source project, maintained exclusively by volunteers. Given Mocha’s use of function expressions to define suites and test cases, it’s straightforward to generate your tests dynamically. No special syntax is required — plain ol’ JavaScript can be used to achieve functionality similar to “parameterized” tests, which you may have seen in other frameworks. -
