/*

|
* 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.
