SlimerJS is useful to do functional tests, page automation, network monitoring, screen capture, web scraping etc.
SlimerJS is similar to PhantomJs, except that it runs on top of Gecko, the browser engine of Mozilla Firefox, instead of Webkit, and is not truly headless when running with Firefox 55 or older.
SlimerJS is compatible with CasperJS 1.1!!
