Javascript: Selenium setup in NodeJS with Firefox and ES6 modules

First install npm install selenium-webdriver. I'm on 4.0.0.
 
Then import Selenium with ES6 modules. We'll rename them since they're not built with ES6 modules in mind.

import * as webdriver from 'selenium-webdriver'
import * as firefox from 'selenium-webdriver/firefox'
let ff = firefox.default; 
let wd = webdriver.default

Then tell Selenium where your Firefox binary is and create the selenium instance.

let options = new ff.Options().setBinary('/usr/bin/firefox')
let browser = new wd.Builder().forBrowser('firefox').setFirefoxOptions(options).build()

Selenium will respond with promises. This is a little annoying so let's use an async function and use await.

async function test() {
  await browser.get("http://localhost:8080/")
  let next = await browser.findElement(wd.By.linkText("next"))
  await next.click()
  let pageSource = await browser.getPageSource()
  let hasPage = pageSource.indexOf("Page 2 of 2") != -1
  assert.equal(hasPage, true, "Checking if we're on page 2")
})

Finally we use the findElement method, once we've loaded a page, and then use the By class to find the link text. Then we click on it.
 
We then get the page source and do some string searching on that to use a normal nodejs assert statement.
