This could be done at line 44 and we wouldn't need 18. Unless this is a pattern
you want to do consistently.

I guess this is a pattern, though perhaps one we should fix in a separate CL.

Most of the other tests set |initDataType| and |initData| at the same time, so I
tried to use the same pattern everywhere.

                     return access.createMediaKeys();
                 }).then(function(mediaKeys) {
                     mediaKeySession = mediaKeys.createSession();
                     waitForEventAndRunStep('message', mediaKeySession, processMessage, test);
-                    return mediaKeySession.generateRequest(initDataType, getInitData(initDataType));
+                    return mediaKeySession.generateRequest(initDataType, initData);
                 });
             }, 'Clear Key update() with non-ASCII response.');
         </script>
