Galen Framework

What Galen Framework is

Galen Framework checks responsive website layouts and visual details against specifications that users define. It opens a page in a browser, resizes it to a specified size and tests the resulting layout against those rules. Galen uses Selenium to interact with page elements and inspect their locations and dimensions. Its visual checks include image comparison and color-scheme verification. After a run, it can produce HTML reports with screenshots and highlights for misaligned elements, and it also supports TestNG reports. Tests can be written in JavaScript or Java; Java projects can use Galen as a Maven dependency. The site describes running tests through Selenium Grid and cloud services including BrowserStack, Sauce Labs, HeadSpin and LambdaTest. Galen is free under the Apache License, Version 2.0, and cross-browser capture and CI/CD integrations are listed. It runs on Linux, macOS and Windows and requires Java version 1.8 or greater. Installation instructions are manual; Windows has no installer and requires adding galen.bat to PATH. The listed download page includes version 2.4.4 binary and source archives.
