In my years at Netflix, I've learned a lot about testing. It's not just about the code, it's about the culture as well.
Besides the cultural aspect is the need to have a cohesive tool set. When I first joined [my team at Netflix], we had unit tests that were all over the place. We had Jest, we had Mocha, I think we had some Enzyme tests too. Now, we've kind of unified on a standard set of way of writing tests
