The type 'ElementClass' is lacking several key properties, specifically context, setState, forceUpdate, props, and refs

I'm currently developing a web application using NextJS with Typescript. During my testing phase with Jest+Enzyme, I encountered the following error message:

** Test suite failed to run

TypeScript diagnostics (customize using `[jest-config].globals.ts-jest.diagnostics` option):
__tests__/Quest.spec.tsx:15:27 - error TS2605:

JSX element type 'Quest' is not a constructor function for JSX elements. Type 'Quest' is missing properties like context, setState, forceUpdate, props, and refs from type 'ElementClass'.

**

Included below are excerpts from my Test file and the code being tested:

Quest.spec.tsx (Test file)

import * as React from 'react';
import { mount } from 'enzyme';
import Quest from '../Quest';

describe('Quest page', () => {
  it('should render without throwing an error', function () {
    const wrapper = mount(<Quest/>);
  })
}) 

Answer №1

To address this issue, I successfully resolved it by executing the command: yarn upgrade @types/react@latest Then, I proceeded to modify the import statements in both my test.tsx file and primary code file to import * as React from 'react';
