How to check code that uses whatwg-fetch with mocha?

Question

I use https://github.com/github/fetch in my application that works fine, but I would like to test my code with Mocha and babel ever since I write ES2016.

This does not work. I get:

1) testApi.js Test api error handling:
 ReferenceError: fetch is not defined
  at callApi (callApi.js:10:10)
  at Context.<anonymous> (testApi.js:8:40)

Because well, the sample is not defined. When I create a selection for the browser, webpack is exposed.

I tried using https://github.com/bitinn/node-fetch , but the api is slightly different and requires, for example, a full URL instead of relative paths.

Is there a solution to this problem?

Mocha node-fetch:

// Support server-side fetch for tests.
let fetch = (typeof window === 'undefined')
  ? require('node-fetch')
  : window.fetch
;
