In Chrome, is there any way to manually trigger a background sync for testing/development purposes?

You can now use a force sync in developer tools in Chrome on your service worker.
Go Dev Tools --> Application --> Service Worker and you will see Sync button and next to it a space to write commands.

There's no way to do this in Chrome right now (April 2016). Follow this bug for updates.
