PHPUnit/Selenium test suite runner. Runs single test suite on multiple browser and devices async.

phpunit-selenium-runner.js

/**
 * Lighweight node app that will run phpunit tests async. The concept is to start the app with a environment flag and
 * a CSV of browsers. App will then spawn child processes for each browser running your phpunit/selenium test suite
 * with that browser and env flag passed. The result is a single test suite run concurrently on multiple browsers and
 * devices with a single win/fail result from the node.js app.
