+/**

+ * been submitted. This function will also test the crash
+ * reports extra data to see if it matches expectedExtra.

+ * @param expectedExtra (object)
+ *        An Object whose key-value pairs will be compared
+ *        against the key-value pairs in the extra data of the
+ *        crash report. A test failure will occur if there is
+ *        a mismatch.
+ *
+ *        If the value of the key-value pair is "null", this will
+ *        be interpreted as "this key should not be included in the
+ *        extra data", and will cause a test failure if it is detected
+ *        in the crash report.
+ *
+ *        Note that this will ignore any keys that are not included
+ *        in expectedExtra. It's possible that the crash report
+ *        will contain other extra information that is not
+ *        compared against.
