A framework based on Selenium and written in Java, which allows you to test the layout of a site both for testing adaptive design for various sizes, and for testing the support of different browsers. It has its own syntax and therefore requires some resources to create tests.

You can set up your tests to run in a cloud like Sauce Labs or BrowserStack so that you can even test your responsive websites on different mobile devices. Galen can run multiple tests in parallel which is also a nice time saver.
