You can use the listenOnce method instead, since this should only occur once.
See
https://cs.chromium.org/chromium/src/chrome/test/data/webui/settings/people_p...
for an example.

Done. Also did to the test case above which is the place I copy the code from.

+            if (event.detail.page == 'create-user-page')
+              resolve();
+          });

   }
 
   return {
     registerTests: registerTests,
   };
