    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.

    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.

    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.

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.

    phantomas

    phantomas

    Headless Chromium-based web performance metrics collector

    Headless Chromium-based modular web performance metrics collector. Modular approach, each metric is generated by a separate "module". phantomas "core" acts as an events emitter that each module can hook into. In-depth metrics such as: number of events bound via jQuery, calls to window.writeor complex and duplicated CSS selectors (via analyze-css). JSON as an output format. Easy integration with other nodejs projects via CommonJS module (see API docs). Metrics can be emitted from the JavaScript code of the page phantomas is run against (thanks to helper functions available in window.__phantomas). Device profiles allow phantomas to emulate mobile or tablet (by setting a proper user agent and viewport). phantomas comes as a CommonJS module that you can use in your nodejs projects. Use grunt to automate daily dev tasks, including your's application web performance.

    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.

    jest-puppe-shots

    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.

    Bundlesize

    Bundlesize

    Keep your bundle size in check

    Add it to your scripts in package.json. Or you can use it with npx from NPM 5.2+. bundlesize accepts an array of files to check. You can give a different file by using the --config flag. If the names of your build files are not predictable, you can use the glob pattern to specify files. This is common if you append a hash to the name or use a tool like create-react-app/nextjs. It will match multiple files if necessary and create a new row for each file. By default, bundlesize gzips your build files before comparing.

    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.

    Sinon.JS

    Sinon.JS

    Test spies, stubs and mocks for JavaScript

    Standalone test spies, stubs and mocks for JavaScript. Works with any unit testing framework. As before, Sinon.JS provides utilities that help test frameworks reduce the boiler-plate. As of Sinon 10 we stopped maintaining compatibility with legacy browsers. Instead, we focus on compatibility with evergreen browsers, Node.js LTS versions and recent Safari versions. The most up-to-date reference on which runtimes and browsers we support can be found by looking at our compatibility docs. Fake timers are synchronous implementations of setTimeout and friends that Sinon.JS can overwrite the global functions with to allow you to more easily test code using them. A test spy is a function that records arguments, return value, the value of this and exception thrown (if any) for all its calls. There are two types of spies: Some are anonymous functions, while others wrap methods that already exist in the system under test. Mocks should only be used for the method under test.
