var webdriver = require('selenium-webdriver');
var driver = new webdriver.Builder().forBrowser('chrome').build();
driver.get('http://www.google.com');
driver.findElement({name: 'q'}).sendKeys('webdriverjs');
driver.findElement({name: 'q'}).sendKeys(webdriver.Key.ENTER);
driver.manage().window().maximize();
driver.wait(webdriver.until.elementLocated({xpath: '//*[#id="rso"]/div/div/div[1]/div/div/h3/a'}), 30000);
driver.findElement({xpath: '//*[#id="rso"]/div/div/div[1]/div/div/h3/a'}).click();
