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.

...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.

Differencify is a library for visual regression testing via comparing your local changes with reference screenshots of your website. It is built on top of chrome headless using Puppeteer.

Wraith is a screenshot comparison tool, created by developers at BBC News. Wraith uses a headless browser to create screenshots of webpages on different environments (or at different moments in time) and then creates a diff of the two images; the affected areas are highlighted in blue. There are two main modes for using Wraith, 'capture' mode and 'history' mode. Wraith has some built-in JavaScript and configuration file templates for you to get started with right away. If you wish to take...

Visual regression testing for web apps. Supports screen rendering with Chrome-headless. Add your own interactions with the Playwright and Puppeteer scripting. BackstopJS automates visual regression testing of your responsive web UI by comparing DOM screenshots over time.

Gemini is a utility for regression testing the visual appearance of web pages. Each of the blocks that are being tested may be in one of the determined states. States are tested with the help of chains of step-by-step actions declared in a block's test suites.

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.
