Visual Regression Tracker

Open source, self hosted solution for visual testing and managing results of visual testing.

Hello

How it works

Service receives images, performs pixel by pixel comparison with it’s previously accepted baseline and provides immediate results in order to catch unexpected changes.

Demo

Features

  • Automation framework independent - no need to stick with specific automation tool, integrate with existing one
  • Platform independent - web, mobile, desktop etc. as long as you could make a screenshot
  • Baseline history - track how baseline image changed since the beginning
  • Ignore regions - improve stability by ignoring not important or not controllable parts of image
  • Language support - JS, Java, Python, .Net or any other via REST API (need more?)
  • Easy setup - everything is inside Docker images
  • Self-hosted - keep your data save inside your intranet

Glossary

  • TestVariation - historical record of Baselines by Name + Branch + OS + Browser + Viewport + Device,
  • Baseline - validated and accepted image, latest will be used as expected result in TestRun
  • TestRun - result of comparing image against Baseline
  • Build - list of TestRuns
  • Project - list of Builds and TestVariations

Set up

Linux, macOS, WSL

  1. Install Docker
  2. Download the installation script
curl https://raw.githubusercontent.com/Visual-Regression-Tracker/Visual-Regression-Tracker/master/vrt-install.sh -o vrt-install.sh

Success setup

Integration

Use implemented libraries to integrate with existing automated suites by adding assertions based on image comparison. We provide native integration with automation libraries, core SDK and Rest API interfaces that allow the system to be used with any existing programming language.

Contribution

  1. Try it, raise tickets with ideas, questions, bugs and share feedback :)
  2. More language support for SDK
  3. More integration with specific testing frameworks (agents)
