Tiny QUnit async test helper, eliminates pyramid code in async tests with multiple assertions, each requiring its own delay.

QUnit.chain

/**
 * testAsyncStepsWithPause
 * Executes any number of async Qunit tests with a pause between each step
 *
 * Author: Matthew O'Riordan, http://mattheworiordan.com
 *
 * Params:
 * @timeToWait: milliseconds between running method and running tests
 * @methods: 1+ function arguments passed in the format:
 *   function() {
 *      // execute code here which requires the tests to wait for @timeToWait
 *      return function() {
 *        // execute assertions here, will be executed after @timeToWait
 *      }
 *   }, ...

How ironic after trawling google i find you :D I am using your helper to delay a stopwatch counter for a webkit app that needs a delayed (a)syncronous test to ensure the chronometer stops, pauses and restarts correctly. It was difficult to find anything in QUnit forums to achieve this type of testing. Thanks for sharing your work. Regards. Bruce.

Ah, glad to help ;)
