I wouldn’t put in Enzyme anymore, it’s been good but i see it being use wrong a lot and we need something more opinionated.
There is still a huge focus in companies on the exact division of unit/integration/end-to-end plus 100% coverage and these concepts for frontend have become counter-productive.
Enzyme give you all the tools to create an insane amount of brittle tests, as useful as it seems in the beginning.
I’m hopeful react-testing-library will be better, giving you not just some simple tools, but a new way of thinking about testing front-end, but we will see.
