## What it is
Galen Framework is an open-source tool for testing the layout and responsive design of web applications, using a human-readable spec language to describe element positions relative to each other at different browser sizes. Built on Selenium, it also supports functional testing in both JavaScript and Java with rich HTML reporting.

## Use cases
- test responsive website layout across different screen sizes
- verify element positions and dimensions relative to each other on a page
- run cross-browser layout tests on Selenium Grid or cloud services like BrowserStack
- write functional end-to-end tests in JavaScript or Java
- compare page elements against reference images with error tolerance
- check color schemes and text of page elements
- generate layout reports with screenshots highlighting broken elements

## When to avoid
- you need a modern, actively maintained tool - the latest release is from 2022 and development has stalled
- you only need simple screenshot-diff visual testing without positional specs
- your stack is Python, Ruby, or other languages without first-class Galen support
- you want a pure JavaScript/npm-native testing workflow

## Facets
- artifact type: framework
