pub fn assign_location(url: &str)Expand description
Another document loads at url — a link followed, or a request_load carried out. The page
that asked is gone; the location and the back stack move to url; the load is the first thing
the new document’s navigation log records (RouteOp::Load); and the document is empty, since
what url serves is another page’s content, outside the page under test. The test’s own
answers for requests survive, as they do across a reload.
