    Happo

    Happo

    Visual diffing in CI for user interfaces

    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 all depends on your existing tech stack, your application, your experience with other test frameworks, and more.

    Hermione

    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.

    Argus Eyes

    Argus Eyes

    A lightweight commandline tool for visual regression testing of UI

    A lightweight command line tool for visual regression testing of UI components. After installing, you want to tell argus eyes which pages and which components to check for visual regression. Argus eyes work by going over a straightforward JSON file containing the resolutions you want to capture, as well as the pages with theirs url's, and the components with their CSS-selectors. Once argus eyes know where to find the components, it's time for some command line action. The first command you want to use is $ argus-eyes capture master. This makes argus eyes go over the config file and take screenshots of all specified components in there. The screenshots are saved in .argus-eyes/master and this set of screenshots can be compared with another set.

    Detox

    Detox

    Gray box end-to-end testing and automation framework for mobile apps

    High velocity native mobile development requires us to adopt continuous integration workflows, which means our reliance on manual QA has to drop significantly. Detox tests your mobile app while it's running in a real device/simulator, interacting with it just like a real user. The most difficult part of automated testing on mobile is the tip of the testing pyramid - E2E. The core problem with E2E tests is flakiness, tests are usually not deterministic. 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.

    Appium

    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 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).

    CSS Critic

    CSS Critic

    Lightweight CSS regression testing

    A lightweight tool for regression testing of Cascading Style Sheets. Your web stack should be fully testable. CSS Critic closes the gap in front-end testing and makes HTML & CSS testable - no more broken UI. For example, make it supervise changes to your project's responsive style guide so you know things are looking good. We believe that your UI will change often enough that a lightweight process on managing changes (near instant feedback, anyone?) is more important than a heavy-weight one which could offer tighter control. Also, CSS Critic aims at bridging the gap between user experience (UX) people and (UI) developers. You probably won't find an easier way of sharing your UI tests than the simple web page that CSS Critic basically is. And don't feel put down by the "CSS" bit, you may throw anything at it that can be converted into a simple image.

    Karma

    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.

    Loki

    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.

    Nodeunit

    Nodeunit

    Easy unit testing in node.js and the browser

    Nodeunit is a lightweight and simple unit testing framework for Node.js that follows a minimalistic approach inspired by traditional xUnit testing patterns. It allows developers to write test cases as plain JavaScript functions, making it easy to integrate into existing projects without requiring complex setup or configuration.

Nodeunit supports both synchronous and asynchronous tests, enabling developers to validate code that relies on callbacks or promises. It also includes features for grouping tests into modules and organizing test suites for better structure and readability. The output is designed to be clear and informative, helping developers quickly identify failing tests and debug issues.

    LazyLoad

    LazyLoad

    LazyLoad is a lightweight, flexible script that speeds up your website

    LazyLoad is a fast, lightweight and flexible script that speeds up your web application by loading images only as they enter the viewport. LazyLoad supports responsive images. LazyLoad is a lightweight (2.4 kB) and flexible script that speeds up your web application by deferring the loading of your below-the-fold images, animated SVGs, videos and iframes to when they will enter the viewport. It’s written in plain “vanilla” JavaScript, it leverages the IntersectionObserver API, it supports responsive images, it optimizes your website for slower connections, and can enable native lazy loading. To display content images on your pages, always use the img tag. This would benefit the SEO and the accessibility of your website. To understand if your images are content or background, ask yourself: “would my website user like to see those images when printing out the page?”. If the answer is “yes”, then your images are content images and you should avoid using background images to display them.

    Protractor

    Protractor

    E2E test framework for Angular apps

    Protractor is an end-to-end test framework for Angular and AngularJS applications. Protractor runs tests against your application running in a real browser, interacting with it as a user would. Protractor is built on top of WebDriverJS, which uses native events and browser-specific drivers to interact with your application as a user would. Protractor supports Angular-specific locator strategies, which allows you to test Angular-specific elements without any setup effort on your part. You no longer need to add waits and sleeps to your test. Protractor can automatically execute the next step in your test the moment the webpage finishes pending tasks, so you don’t have to worry about waiting for your test and webpage to sync. Protractor needs two files to run, a spec file and a configuration file. Open a new command line or terminal window and create a clean folder for testing.

    jest-puppe-shots

    A Jest plugin for creating screenshots of React components

    A Jest plugin for creating screenshots of React components with a little help of Puppeteer. A jest-puppy-shots is a Jest plugin that can help you create Visual Regression tests for your React components. If you ever used Enzyme or Snapshots you will love the jest-puppe-shots. 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 Jest and create real screenshots of your components.

    matchMedia() polyfill

    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.
