/*
* This file is meant to provide common infrastructure for several consumers.
* The consumer is expected to define the following things:
*
* 1) An verifyPromiseGlobal function which does whatever test the consumer
* wants.
* 2) An isXrayArgumentTest global boolean, because some of these tests act
* differenly based on that boolean.
* 3) A function named getPromise. This function is given a global object and a
* single argument to use for getting the promise. The getPromise function
* is expected to trigger the canonical Promise.resolve for the given global
* with the given argument in some way that depends on the test, and return
* the result.
* 4) A subframe (frames[0]) which can be used as a second global for creating
* promises.
