Jest configuration - test environment value

[megaurav2002]

I was just trying out this but i was struggling to render the css styles in my snapshot. After spending a few hours, i realized i had "testEnvironment": "node" set.

Wondering if this should be a documentation update or a warning that gets shown when the tests are run. I can try to contribute with this.

Hi! Thanks for the issue. Yeah, let's just add a note to the docs. Thanks!

Thanks @kentcdodds. I just forked this repo and ran "npm start validate" and got an error. Happy to update snapshot but wanted to check if that's ok.

Go ahead and update. We'll see if Travis does the same. Thanks!
