CasperJS

CasperJS is basically a finer interface to support headless browser testing for your project.

Headless browser testing is a testing method where developers use a headless browser like SlimerJS, PhantomJS or trifleJS (not supported by CasperJS) to simulate a browser and see how the page reacts.

While the original tools can do this on their own, CasperJS supports a much easier to use interface, heavily inclined towards JavaScript aficionados.
