Browser-Based Acceptance Testing with NodeJS

This sample project demonstrates how to use Express, WebdriverIO, Chrome, and Jest to write browser-based acceptance specs.

Steps:

1. Drop in the acceptance_spec_helper module into your project located currently in the spec/acceptance directory
2. Import it into each of the acceptance spec suites:

   import { setupEnvironment, browser, localUrl } from './acceptance_spec_helper'

3. Before any test code such as a describe suite, add a call to the setupEnvironment function:

   setupEnvironment()
   
   // rest of the test suite

   It will set up all the before/after calls. When those are called during test execution it will start and stop the express server, chromedriver, and webdriverio. It'll also use the get-port library to parallelize the execution of acceptance specs if jest decides it is more efficient.
4. Use the browser import and localUrl functions to drive the browser instance:

   await browser.url(localUrl())
   const result = await browser.getTitle()
