/*
* This file is meant to provide common infrastructure for several consumers.
* The consumer is expected to define the following things:
*
* 1) A verifyPromiseGlobal function which does whatever test the consumer
* wants. This function is passed a promise and the global whose
* TestFunctions was used to get the promise.
* 2) A expectedExceptionGlobal function which is handed the global whose
* TestFunctions was used to trigger the exception and should return the
* global the exception is expected to live in.
* 3) A subframe (frames[0]) which can be used as a second global for creating
* promises.
