var casper = require("casper").create();
var urlLogin= casper.cli.get(0);
casper.start(urlLogin, function() {
 this.echo(this.getTitle());
 this.waitForSelector('form[action="' + urlLogin + '"]');
});
//Login as a customer
casper.then(function(){
 this.fill('form[action="' + urlLogin + '"]' ,{ 
     email: 'example@example.com', 
     password:  'xyz123'
 }, true);
 this.echo('frontend login');

    this.echo(this.getTitle(),"INFO");
});

//Add product into the cart
casper.then(function(){
this.click('#content > div:nth-child(3) > div > div > div:nth-child(2) > div.button-group > button:nth-child(1)');
 this.echo('Product added into the cart', "INFO");

});

casper.wait(2000, function(){
   this.echo(this.getCurrentUrl());
});

//Open the shopping cart page
casper.thenOpen('http://example.com/index.php?route=checkout/cart');

   casper.wait(2000, function(){
    this.echo(this.getCurrentUrl(),"INFO");
});

//Add billing address
