PhantomJS, CasterJS 설치 및 사용
PhantomJS: is a headless WebKit with JavaScript API. (WebKit:Chrome, safari 등 브라우저 없이 JS를 사용할 수 있음)
CasperJS: is a navigation scripting & testing utility that runs on top/alongside of PhantomJS.
The Api of Phantom JS is based on JavaScript: how would you execute code in a browser? Web sites JavaScript code is sandboxed, so that it does not interact with the main tool. Nothing is rendered to the screen like Selenium, we use the command-line.

----설치요약
Guidouil's answer put me on the right track. I had to add one additional symlink to /usr/bin/, and I did direct symlinks for all 3 - see below.
I'm installing on Ubuntu server Natty Narwhal.
This is exactly what I did.
cd /usr/local/share
wget http://phantomjs.googlecode.com/files/phantomjs-1.9.1-linux-x86_64.tar.bz2
tar -xjf phantomjs-1.9.1-linux-x86_64.tar.bz2
sudo ln -s /usr/local/share/phantomjs-1.9.1-linux-x86_64/bin/phantomjs /usr/local/share/phantomjs
sudo ln -s /usr/local/share/phantomjs-1.9.1-linux-x86_64/bin/phantomjs /usr/local/bin/phantomjs
sudo ln -s /usr/local/share/phantomjs-1.9.1-linux-x86_64/bin/phantomjs /usr/bin/phantomjs
=>And finally when I do
phantomjs -v
I get 1.9.1
* when you get error like "error while loading shared libraries: libfontconfig.so.1: cannot open shared object file: No such file or directory"
=> apt-get install libfontconfig1
Thanks Guidouil. Perfect timing. I've been working on this for a whole day. Sorry, I don't have enough reputation yet to vote you up, yet.
If anyone sees any problems with what I've done, please let me know.
