var chrome = require(“selenium-webdriver/chrome”);
var options = new chrome.Options();
options.addArguments(“start-maximized”);
options.addArguments(“disable-popup-blocking”);
options.addArguments(“test-type”);
var driver = new webdriver.Builder().
withCapabilities(options.toCapabilities()).build();
//We can use below code block to check if element exists on the webpage.
driver.get(“https://www.softpost.org”);
var webElements = driver.findElements(By.id(“myid”));
webElements.then(function (elements) {
if(elements.length==0)
console.log(“Element myid not present”);
