Simply the best explanation from entire Youtube. I'm studying react from 2 years and test library was the worst part to find some good videos. Congrats!

Thank you so much for this tutorial! I would agree with the other comments too about seeing a more involved testing suite using a state library. But this was by far the best video I've seen on using jest. Keep the videos coming

Great tutorial mate, would love to see a more complicated test suite on a component that is using redux!

Hi Kris ! thanks for explanation, I know this video is 2 years old, is it possible for you to re-explain it with current state of Jest + React Testing Library? Probably some improvement here and there? And maybe you could help to explain about testing user event + mocking child component inside the component being tested. Thanks !

This is a very simple and great tutorial 👍
