* Test that a bunch of service worker coding errors and failure modes that
* might otherwise be hard to diagnose are surfaced as console error messages.
* The driving use-case is minimizing cursing from a developer looking at a
* document in Firefox testing a page that involves service workers.
*
* This test assumes that errors will be reported via
* ServiceWorkerManager::ReportToAllClients and that that method is reliable and
* tested via some other file.
