WIP!

Browser = require 'selenium-webdriver-simple'
config  =
    browser: 'chrome'     # could be any browser `selenium-webdriver` supports
    verbose: yes          # be verbose
    selenium:
        autostart: no     # don't run `selenium-server` automatically
        path: './vendor'  # path with `selenium-server-standalone`

browser = new Browser(config)
... 

• selenium-server-standalone must present in path defined in config.selenium.path option. Get it here.
• chromedriver must present in $PATH in order to use Chrome/Chromium browser. Get it here.
• phantomjs driver is kinda broken, so don't use it wich mocha

• lib/browser parses input config and passes selenium part to lib/selenium during initialize stage
• after SeleniumServer is initialized and running, Browser is ready to accept orders
• Browser#quit shutdowns both Browser and SeleniumServer

Run npm test.

• wrap Browser#find with BrowserElement class (or find another way) to be able to do advanced actions like finding the child elements
• think about headless run with help of Xvfb OOB
• catch all exception thrown by selenium-webdriver to provide fallbacks
