Selenium
Browser automation framework and ecosystem
Selenium automates browsers. That's it! What you do with that power is entirely up to you. Primarily it is for automating web applications for testing purposes, but is certainly not limited to just that. Boring web-based administration tasks can (and should) also be automated as well. If you want to create robust, browser-based regression automation suites and tests, scale and distribute scripts across many environments, then you want to use Selenium WebDriver, a collection of language specific bindings to drive a browser - the way it is meant to be driven. If you want to create quick bug reproduction scripts, create scripts to aid in automation-aided exploratory testing, then you want to use Selenium IDE; a Chrome and Firefox add-on that will do simple record-and-playback of interactions with the browser. If you want to scale by distributing and running tests on several machines and manage multiple environments from a central point. -

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. -

IPFS Web UI
A frontend for an IPFS node
A web interface to IPFS, shipped with Kubo, and ipfs-desktop. Check on your node stats, explore the IPLD powered merkle forest, see peers around the world and manage your files, without needing to touch the CLI. When working on the code, run an ipfs daemon, the local dev server, the unit tests, and the storybook component viewer and see the results of your changes as you save files. If you need to run IPFS in a Docker container, you can still have Web UI available by exposing both the Gateway and Web UI ports. The end-to-end tests (E2E) test the full app in a headless Chromium browser. They spawn real IPFS node for HTTP API and a static HTTP server to serve the app. The purpose of those tests is not being comprehensible, but act as a quick regression and integration suite. -

ZetaJS
JS wrapper for ZetaOffice in the browser
The zeta.js library provides the facilities to run an instance of ZetaOffice integrated into your web site, allowing you to control it with JavaScript code via the LibreOffice UNO technology. Use cases range from an in-browser office suite that looks and feels just like its desktop counterpart, to fine-tuned custom text editing and spreadsheet capabilities embedded in your website, to a headless zetajs instance that does document conversion in the background. -

Loki
Visual Regression Testing for Storybook
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. -

SlimerJS
A scriptable browser like PhantomJS, based on Firefox
SlimerJS is a scriptable browser. It allows you to manipulate a web page with an external Javascript script: opening a webpage, clicking on links, modifying the content... It is useful to do functional tests, page automation, network monitoring, screen capture etc. It is a tool like PhantomJs, except that it runs Gecko instead of Webkit, and it is headless when using Firefox 56+. It can be used with Firefox 59. Higher version of Firefox is not supported and probably will not be supported in the future, as the development is suspended for now. SlimerJS provides the same API of PhantomJS. The current version of SlimerJS is highly compatible with PhantomJS 2.1. See current release notes in docs/release-notes-*.rst, and read the compatibility table to know the implementation level. The main goal of SlimerJS is to allow to execute all scripts developed for PhantomJS. So you could use tools like CasperJS. In fact, CasperJs 1.1 and higher can be executed with SlimerJS! -

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. -

Critters
A Webpack plugin to inline your critical CSS and lazy-load the rest
It's a little different from other options because it doesn't use a headless browser to render content. This tradeoff allows Critters to be very fast and lightweight. It also means Critters inlines all CSS rules used by your document, rather than only those needed for above-the-fold content. Critters' design makes it a good fit when inlining critical CSS for prerendered/SSR'd Single Page Applications. It was developed to be an excellent compliment to the prerender-loader, combining to dramatically improve first paint time for most Single Page Applications. Import Critters into your Webpack configuration and add it to your list of plugins. That's it! Now when you run Webpack, the CSS used by your HTML will be inlined and the imports for your full CSS will be converted to load asynchronously. Create a Critters plugin instance with the given options. -

Zombie.js
Fast, full-stack, headless browser testing using node.js
Insanely fast, headless full-stack testing using Node.js. Zombie 6.x is tested to work with Node 8 or later. If you need to use Node 6, consider using Zombie 5.x. If you’re going to write an insanely fast, headless browser, how can you not call it Zombie? Zombie it is. Zombie.js is a lightweight framework for testing client-side JavaScript code in a simulated environment. No browser required. Zombie will work with other testing frameworks. Since Mocha supports promises. Just like your favorite Web browser, Zombie manages multiple open windows as tabs. New browsers start without any open tabs. As you visit the first page, Zombie will open a tab for it. All operations against the browser object operate on the currently active tab (window) and most of the time you only need to interact with that one tab. You can access it directly via browser.window. You can access all open tabs from browser.tabs. This property is an associative array, you can access each tab by its index number. -
