How to login into a website with CasperJS?

Question

How can I login with CasperJS by submitting a form. I searched google and haven\'t found any good examples about it.

Here is a slightly changed version of the code from Ngo Hung. The selector for the username was off as was the assignment of the userAgent:

var casper = require('casper').create({   
    verbose: true, 
    logLevel: 'debug',
    userAgent: 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_6_8) AppleWebKit/537.22 (KHTML, like Gecko) Chrome/25.0.1364.172 Safari/537.22',
    pageSettings: {
      loadImages:  false,         // The WebPage instance used by Casper will
      loadPlugins: false         // use these settings
    }
});

// print out all the messages in the headless browser context
casper.on('remote.message', function(msg) {
    this.echo('remote message caught: ' + msg);
});

// print out all the messages in the headless browser context
casper.on("page.error", function(msg, trace) {
    this.echo("Page Error: " + msg, "ERROR");
});

var url = 'http://www.facebook.com/';

casper.start(url, function() {
    console.log("page loaded");
    this.test.assertExists('form#login_form', 'form is found');
    this.fill('form#login_form', { 
        email: '****', 
        pass:  '****'
    }, true);
});

casper.thenEvaluate(function(){
    console.log("Page Title " + document.title);
    console.log("Your name is " + document.querySelector(".fbxWelcomeBoxName").innerHTML);
});

casper.run();

UPDATE: I recommend anyone else to use a site of their own, or at least not facebook.com if they are planning large amounts of testing. Facebook could tell that I was trying to log in over and over started emailing me and making me confirm my account with SMS.
