for basic testing setup this is fine , we probally need a renderer and a test runner to make our lives easy.
I am thinking of rtl or enzyme.
rtl doesn't do shallow so it can be slow sometimes for huge trees , other than that I am in favour of it since its very close to how the user uses the application

Lets actually make this work first, though.
