Unofficial adapter for React 17 for Enzyme.
npm install --save-dev enzyme-adapter-react-17
or, if you're using Yarn:
yarn add --dev enzyme-adapter-react-17
Finally, you need to configure enzyme to use the adapter you want it to use. To do this, you can use the top level configure(...) API.
import Enzyme from 'enzyme';
import Adapter from 'enzyme-adapter-react-17';
Enzyme.configure({ adapter: new Adapter() });
