Update: Just got it working. Following the instructions on this github issue and using `shamefully-hoist=true` with pnpm I got it working. The issue I was facing was with pnpm.

React Testing Library uses jest-dom which has a .getByText() matcher.

vitest-dom extends the standard Jest matchers with convenient methods like .toBeDisabled. Now you can write tests that assert on the state of the DOM. The package is a fork of @testing-library/jest-dom.

jest-dom matchers

At the time of writing this article, it still seems to be an open issue. However, a workaround I found is to add "skipLibCheck": true, to your tsconfig.json 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: https://github.com/testing-library/jest-dom import '@testing-library/jest-dom'; import { server } from './mocks/server'; beforeAll( () => server.listen( { onUnhandledRequest: 'error' } ) ); afterEach( () => server.resetHandlers() ); afterAll( () => server.close() );

Everything you want to do to your test environment such as extends the jest matchers with @testing-library/jest-dom, mock some APIs that’s not implemented in jdom, you can put to config/jest/setupTests.js:
