hi, what represents "#uploadButton"?

Somehow like this.

@ralucasuditu: #uploadButton, this is an ID which represents Upload button.

var path = require('path');

it('should upload file', function() {
var fileToUpload = '../some/path/foo.txt';
var absolutePath = path.resolve(__dirname, fileToUpload);
$('input[type="file"]').sendKeys(absolutePath);

$('#uploadButton').click();
});
