React Testing

react-testing-library

It was a few months ago that my friend and mentor for testing react apps. Ever since then, I no longer just love the idea of testing UIs, but actually love testing them. I have literally dug out and tested all the UI code I gave up on testing because of its complexity :).

This is the “approach” I’m talking about. Test your UIs just as your non-techie friend would. Your user probably neither knows nor cares what your code looks like. And nor should your test. That gives us the power to use TDD on our UIs.

This is how we’re going to write our socket.io-client test — test everything without thinking about the code. Now let’s do it!
