You state that the unit test in listing 4.10 doesn't pass until you've added the code in listing 4.11. But that doesn't seem to be correct, as you already call $bar.start in listing 4.7.

I noticed the same thing. It looks like the test passes under the mounted() hook, as well as the beforeMount() hook.

Thanks guys, I've updated the book to make it clear the beforeMount should be deleted.
