+/*
+ * 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.
