/**
 * 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.
