What Galen Framework is
Galen Framework is a free tool for checking responsive website layouts and appearance against specifications defined by the user. It opens a page in a browser, resizes it to a specified size, and checks the layout against those rules. Galen uses Selenium to interact with page elements and read their positions and dimensions. 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 include 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 distributed under the Apache License, Version 2.0, and its listed plan costs nothing. It runs on Linux, macOS, and Windows and requires Java 1.8 or greater. Installation instructions are manual; Windows has no installer, and setup requires adding galen.bat to PATH. The download page lists version 2.4.4 archives.
