Just wanted to give kudos for your videos. I'm a senior dev, finally dabbling in proper testing and I found this video really easy to understand. I was wondering though, what which point is it better to spy vs mock?

This is awesome! Was pulling my hair out yesterday dealing with jests mock hoisting and trying to change mock resolved for only a specific test, and I'm sure this will help. Why would we favour one over the other?
