CasperJS & PhantomJS: Headless WebKit with JavaScript API

In addition to Zombie, which proves difficult to use on Windows, here are more options for headless full web stack testing:

PhantomJS: Headless WebKit with JavaScript API: "PhantomJS is a headless WebKit scriptable with a JavaScript API. It has fast and native support for various web standards: DOM handling, CSS selector, JSON, Canvas, and SVG."

CasperJS is "an open source navigation scripting & testing utility written in Javascript and based on PhantomJS — the scriptable headless WebKit engine. It eases the process of defining a full navigation scenario and provides useful high-level functions, methods & syntactic sugar for doing common tasks such as:

defining & ordering browsing navigation steps
filling & submitting forms
clicking & following links
capturing screenshots of a page (or part of it)
testing remote DOM
logging events
downloading resources, including binary ones
writing functional test suites, saving results as JUnit XML
scraping Web contents"
