SlimerJS

A headless browser is a browser without a user interface, used mainly for testing purposes, to simulate the presence of a browser, in this case the Gecko engine.

Just like the original PhantomJS, SlimerJS can access Web pages, get the content from the page, compile it and log or send it to other programs.

Most of the SlimerJS code has been directly ported from PhantomJS, but features specific to Firefox have also been implemented to closely simulate the Gecko engine.

This makes it an ideal tool for testing departments, a much more powerful testing toolkit compared to classic unit testing frameworks.
