Selenium WebDriver: Learn to automate a browser with WebDriver and JavaScript

I gave a talk on automating a browser in JavaScript (useful for scraping data, testing, etc.) at SeleniumConf 2016. You can:

• Watch this talk on YouTube
• View the slides online
• Watch the same talk with GoPro and heart rate data
• Experiment with the code

Here's an example of counting the number of Wiki hyperlinks on a Wiki page.

const webdriver = require('selenium-webdriver');

const browser = new webdriver
	.Builder()
	.usingServer()
	.withCapabilities({
		'browserName': 'chrome'
	}).build();

async function start() {
	browser.get('http://en.wikipedia.org/wiki/Wiki');
	const links = await browser.findElements(webdriver.By.css('[href^="/wiki/"]'))
	console.log('Found', links.length, 'Wiki links.' )
	browser.quit();
}

start();

In Node v7, you can run it like this:

$ npm i selenium-webdriver
$ node --harmony-async-await Wiki.js
> Found 396 Wiki links.
