Testing React Components with Enzyme - Had to upgrade to React 16

I am working on the Testing React Components with Enzyme tutorial.

I ran into errors using the original project files, I had to upgrade react, react-dom to version 16. I then had this error:

"Enzyme Internal Error: Enzyme expects an adapter to be configured, but found none."

So, I installed enzyme-adapter-react-16 and added this code snippet to Repositories.spec.js:

//Begin code snippet import Adapter from 'enzyme-adapter-react-16'; import { configure } from 'enzyme'; configure({adapter: new Adapter()}); //End code snippet

I also had to remove PropTypes from Repository and Repositories because it has been deprecated in React-16.

Once I did this, everything seemed to work.

Thanks, John
