New code and user testing tools and frameworks seem to pop up every day. Below is a varied list of code tools that accomplish various testing needs. Each one should be investigated to make sure it fits with your tech stack and technical needs.
Karma is a framework-agnostic test runner for connected browsers. The results of each test against each browser are examined and displayed via the command line to the developer so they can see which browsers and tests passed or failed.
Selenium has a straightforward aim: to automate browsers. It is used primarily for automating web applications for testing purposes, but it can just as easily take care of web-based administrative tasks.
WebdriverIO lets users control a browser or a mobile application with just a few lines of code, making test code simple, concise and easy to read. The integrated test runner also lets you write asynchronous commands in a synchronous way so that you don’t need to care about how to handle a Promise to avoid racing conditions. Additionally, it takes away all the cumbersome set up work and manages the Selenium session for you.
Nightwatch.js is an easy to use Node.js based End-to-End (E2E) testing solution for browser-based apps and websites. It uses the powerful W3C WebDriver API to perform commands and assertions on DOM elements.
PhantomCSS takes screenshots captured by Casper.js and compares them to baseline images using Resemble.js to test for RGB pixel differences. PhantomCSS then generates image diffs to help you find the cause.
PhantomFlow delivers UI testing with decision trees. It provides an experimental approach to UI testing, based on Decision Trees. A Node.js wrapper for Phantom.js, Casper.js and PhantomCSS, PhantomFlow enables a fluent way of describing user flows in code while generating structured tree data for visualisation.
Percy provides iterative and fast feedback about visual changes, delivering what is calls continuous visual integration. It does this by running with a test suite, taking DOM snapshots, and uploading the, to the Percy service where they are rendered in a modern browser.
