I have a file test_stuff.js that I am running with npm test

It pretty much looks like this:

import { assert } from 'assert';

import { MyProvider } from '../src/index';

import { React } from 'react';



const myProvider = (

  <MyProvider>

  </MyProvider>

);



describe('Array', function() {

  describe('#indexOf()', function() {

    it('should return -1 when the value is not present', function() {

      assert.equal(-1, [1,2,3].indexOf(4));

    });

  });

});

Unfortunately, I get the error

/Users/me/projects/myproj/test/test_stuff.js:11

var myProvider = _react.React.createElement(_index.MyProvider, null);

                             ^



TypeError: Cannot read property 'createElement' of undefined

    at Object.<anonymous> (/Users/me/projects/myproj/test/test_stuff.js:7:7)

What does that mean? I am importing React from 'react' successfully, so why would React be undefined? It is _react.React, whatever that means...
