Yarn test failing - Network request failed

Question

I created a react project using create-react-app however when ran yarn test to see if the initial tests pass I get

TypeError: Netwo         


        

Answer 1

I already solve my problem. I'm following a book entitled "The Road to Learn React" and I think that the one causing my error is the part where I fetch data from an external API. The book forgot to include an import for fetch which is this one:

import fetch from 'isomorphic-fetch'

Then, it solves my problem like a charm.
