/**
* PhantomJS: QUnit test runner from https://github.com/ariya/phantomjs/blob/1.2/examples/run-qunit.js
*
* Wait until the test condition is true or a timeout occurs. Useful for waiting
* on a server response or for a ui change (fadeIn, etc.) to occur.
*
* @param testFx javascript condition that evaluates to a boolean,
* it can be passed in as a string (e.g.: "1 == 1" or "$('#bar').is(':visible')" or
* as a callback function.
* @param onReady what to do when testFx condition is fulfilled,
* it can be passed in as a string (e.g.: "1 == 1" or "$('#bar').is(':visible')" or
* as a callback function.
* @param timeOutMillis the max amount of time to wait. If not specified, 3 sec is used.
