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. -

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. -

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 built on the idea that testing native apps shouldn't require including an SDK or recompiling your app. And that you should be able to use your preferred test practices, frameworks, and tools. 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). -

Jasmine
A JavaScript Testing Framework
Jasmine is a behavior-driven JavaScript development framework for running both browser and Node.js tests. It’s been tested to work on most versions of popular browsers including Safari, Chrome, Firefox, and Internet Explorer. Jasmine does not rely on any other JavaScript frameworks, browsers or DOM, making it suitable for websites, Node.js projects, or just about anywhere that JavaScript can run. Jasmine has everything you need out of the box to test your code, yet retains a low overhead and absolutely no external dependencies. This means, of course, that it is fast. It has a clean, obvious syntax that makes writing tests a breeze. -

Puppeteer
Headless Chrome Node.js API
Puppeteer is a headless Node library that provides a high level API for controlling Chromium or Chrome over the DevTools protocol. It requires zero setup and comes bundled with the Chromium version most suited to it. Puppeteer is headless by default, making it fast to run. However, it can also be set to run full or non-headless Chrome or Chromium, simply set the headless option when launching a browser. Many of the things you can do manually in the browser, you can also do with Puppeteer such as generate page screenshots and PDFs, crawl a Single-Page Application, test Chrome extensions and more. -

Hermione
Browser test runner based on mocha and wdio
Hermione is a utility for integration testing of web pages using WebdriverIO and Mocha. If you are familiar with WebdriverIO and Mocha, you can start writing and running tests in 5 minutes! You need to install Hermione via npm and add a tiny config to your project. When tests are run one by one, it takes a lot of time. Hermione can run tests in parallel sessions in different browsers out of the box. Running of too many tests in parallel can lead to the overloading of the main process CPU usage which causes degradation in test passing time, so Hermione runs all tests in subprocesses in order to solve this problem. -

VBot
JSON based visual regression testing library
A visual regression testing library/tool, aims to quickly automate browser-based tests with minimum development overhead. To test flexibly in different testing scenarios, either testing against web UI wired with backends or just static web pages, VBot exposes API to be used with testing frameworks like mocha or ava, etc. Therefore, the test data variables can be updated according to different conditions, in order to decouple from real backends and avoid false negative results. -

matchMedia() polyfill
matchMedia polyfill for testing media queries in JS
matchMedia() polyfill is a JavaScript polyfill that brings matchMedia-style media query testing to environments that need compatibility support. It lets developers test whether a CSS media type or media query applies directly from JavaScript. 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. -

memory-stats.js
minimal monitor for JS Heap Size via performance.memory
memory-stats.js is a small JavaScript utility that displays page memory usage in a style similar to stats.js. It was inspired by mrdoob’s stats.js and originally came from work related to tquery before becoming a standalone repository. The tool helps developers monitor JavaScript memory behavior directly inside a web page during development or debugging. It works by creating a MemoryStats instance, adding its display element to the DOM, and updating it regularly with requestAnimationFrame. For more precise results, Chrome should be launched with the precise memory information flag, because default memory values may be bucketed. The project is useful for performance debugging, visual memory monitoring, and quick inspection of memory behavior in browser-based experiments. -

Playwright for .NET
.NET version of the Playwright testing and automation library
Playwright for .NET is the official language port of Playwright, the library to automate Chromium, Firefox and WebKit with a single API.
