CasperJS内でcasperjs --versionとphantomjs --versionの確認をする

String.prototype.trim = function () {
    return this.replace(/^\s+|\s+$/g, '');
};
require("child_process").execFile("/usr/local/bin/casperjs", ["--version"], null, function (err, stdout, stderr){
    test.assertEqual("1.1.0-beta3", stdout.trim());
});

require("child_process").execFile("/usr/local/bin/phantomjs", ["--version"], null, function (err, stdout, stderr){
    test.assertEqual("1.9.7", stdout.trim());
