This is probably caused by the React update made in Bug 1312236

Attachment: Bug 1321518 - Fix requireHelper for enzyme.

Bug 1312236 updated React to v15.3.2 which was making webconsole's mocha test fail.
An error was thrown because the path and export we do in requireHelper to make enzyme
able to call React functions was changed.
We fix the require to ReactDOM by using the react-dom.js file, and we add the similar
react-dom-server.js for ReactDomServer functions.

Tests now run like they used to.

If we are only using this for node unit tests, can we include this in package.json instead of importing it as a vendor file and using the require-helper?

This looks fine.  Please update the bottom of the REACT_UPGRADING file to include copying this file
