Which Enzyme adapter works with React 17?

I have a React app, and I want to start writing unit tests with Enzyme. Enzyme's documentation discusses versions of React up to 16.

In src/setupTests.js I currently have

import Enzyme from 'enzyme';
import Adapter from 'enzyme-adapter-react-16';
Enzyme.configure({ adapter: new Adapter() });

But my app uses React version 17.0.1. What enzyme adapter is there for React 17?

What enzyme adapter is there for React 17?

If you have React version 17, you can use this unofficial adapter for React 17 for enzyme.

// src/setupTests.js
import { configure } from 'enzyme';
import Adapter from '@wojtekmaj/enzyme-adapter-react-17';
configure({ adapter: new Adapter() });

See this GitHub issue for more information on the unofficial adapter.

I tried with unofficial adapter '@wojtekmaj/enzyme-adapter-react-17' and it works fine. Thanks @super Jade.

1. clear the npm cache (clearing this may make npm slower, but give it a try).

• npm cache verify and then npm cache clean --force

2. remove your

• node_modules and package-lock.json

3. update npm dependencies in your package.json with "@testing-library/react": "^11.2.5","@wojtekmaj/enzyme-adapter-react-17": "^0.4.1","react": "^17.0.1","react-dom": "^17.0.1",
4. npm i --legacy-peer-deps
5. as @wojtekmaj/enzyme-adapter-react-17 mentioned making a change in the test file.

• import Adapter from '@wojtekmaj/enzyme-adapter-react-17';
• configure ({ adapter: new Adapter() });

add this code in setupTests.js file

// jest-dom adds custom jest matchers for asserting on DOM nodes.
// allows you to do things like:
// expect(element).toHaveTextContent(/react/i)
// learn more:
import '@testing-library/jest-dom';
import Enzyme from 'enzyme';
import Adapter from '@wojtekmaj/enzyme-adapter-react-17';
Enzyme.configure({ adapter: new Adapter() });

I've tried @wojtekmaj/enzyme-adapter-react-17 for React 17, and it does work just fine.

After using npm install --save-dev @wojtekmaj/enzyme-adapter-react-17 you also need to set up enzyme to use the adapter you want it to use, you do so by adding the top level configure API:

/* src/setupTests.js */
import Enzyme from 'enzyme';
import Adapter from '@wojtekmaj/enzyme-adapter-react-17';
Enzyme.configure({ adapter: new Adapter() });
