// This file contains general helpers for navigation/history tests. The goal is
// to make tests more imperative and ordered, instead of requiring lots of
// nested callbacks and jumping back and forth. However,
// html/browsers/browsing-the-web/remote-context-helper/resources/remote-context-helper.js
// might be even better at that, so prefer that when you can.
//
// TODO(domenic): consider unifying with
// overlapping-navigations-and-traversals/resources/helpers.mjs.
