Ah, clever 🎉
Does failTest give an intelligible message if we get there? ie if we run this test without your previous commit, would it be clear what went wrong?

That looks great, assuming there's a line number along with it too, so you can tell it's the _hover on line 618 that caused the failure.

(no it doesn't give a line number, but neither do our normal failTest invocations... lets leave it as is at least for now)

.then(failTest).catch(function(err) {
expect(err).toBe('plotly_unhover did not get called!');
