Hi! So far the course is great. There are a couple of concepts that I can’t wrap my head around yet. In ‘Create a Partial Mock with Spies’ he says that using spies _“make your tests more honest and how your program actually works”_ and that we should prefer spies becase we _“want to work with real data as much as possible”_. But how are spies doing that for us?

Cheers!
