Sorta. The joy of PhantomJS (and of Chimera) is that they use a real browser to run the JS/CSS/HTML/whatever. No simulated DOM; no simulated cookies; etc. Just a real [headless] WebKit browser with all of its quirks and tricks. You can even take screenshots of a real, rendered webpage (which is great for debugging).
