react is not defined

Updated to React 16 and Enzyme 3 - using mocha with webpack

import React from 'react';
import Enzyme, { render } from 'enzyme';
import Adapter from 'enzyme-adapter-react-16';

Enzyme.configure({ adapter: new Adapter() });

describe('...', () => {
  // ...
});

Webpack externals:

  externals: {
    jsdom: 'window',
    'react/addons': true,
    'react/lib/ExecutionEnvironment': true,
    'react/lib/ReactContext': 'window',
    'react-dom/test-utils': true,
    'react-test-renderer/shallow': true,
  },

I get the error ReferenceError: react is not defined

Do you have react-test-renderer in your dev deps? Try npm ls - if it returns nonzero then nothing can be expected to work.

@trigunam this has nothing to do with enzyme. React’s latest blog post says you need both React 17 and also custom babel configuration to be able to avoid importing React.
