var driver = new webdriver.Builder().
    usingServer(server.address()).
//    withCapabilities(webdriver.Capabilities.firefox()).
    withCapabilities(webdriver.Capabilities.phantomjs()).
    build();

driver.get('http://twitter.com');

driver.takeScreenshot().then(function (base64Image) {
    var decodedImage = new Buffer(base64Image, 'base64');
    fs.writeFile('image_decoded.jpg', decodedImage, function(err) {});
    console.log('took screenshot');
});

driver.quit();

action.mouseMove(driver.findElement(webdriver.By.css('.form-signup-home button'))).mouseDown();
