react-testing-library: [4.1.3] Cannot find module 'jest-dom/extend-expect'

If some of you still have the problem: I fixed it by using

import '@testing-library/jest-dom';

instead of jest-dom/jest-dom/extend-expect

This is the recommanded usage by the official documentation

yarn add -D @testing-library/jest-dom

replace import “jest-dom/jest-dom/extend-expect”; with import “@testing-library/jest-dom/extend-expect”;

It’s a separate package

npm install -D jest-dom
# or yarn
yarn add --dev jest-dom

If some of you still have the problem: I fixed it by using

import '@testing-library/jest-dom';

instead of jest-dom/jest-dom/extend-expect

This is the recommanded usage by the official documentation

Thanks it works for me.

You have to install jest-dom manually. Good luck!

Step 1: Uninstall jest-dom(deprecated one) npm uninstall jest-dom

Step 2:Install testing-library/jest-dom npm i @testing-library/jest-dom

Step 3:Replace import “jest-dom/jest-dom/extend-expect”; with import “@testing-library/jest-dom/extend-expect”;

Thanks @stevenYouhana

any update on this? There’s still a lot of mixed info out there - jest-dom is now packaged in, toBeInTheDocument must come from jest-dom, jest-dom is deprecated, it’s @testing-library/jest-dom now, you need to import it, you don’t need to import it… All the set-up guides are out of date.

If I import {toBeInTheDocument} from '@testing-library/jest-dom' then I’m told Cannot find module '@testing-library/jest-dom' and if I don’t then TypeError: expect(...).toBeInTheDocument is not a function

FYI Currently the official documentation recommend us to use

// In tsconfig.json "include": [ "./jest-setup.ts"],

I’ve done that; its in my package.json (^3.1.3)

I am still getting this error nothing is fixing it OK I just got this error

jest-dom has moved to @testing-library/jest-dom. Please uninstall jest-dom and install @testing-library/jest-dom instead, or use an older version of jest-dom. Learn more about this change here: https://github.com/testing-library/dom-testing-library/issues/260 Thanks!

@s-Hale Did you install @testing-library/jest-dom? Either via https://github.com/testing-library/jest-dom#installation or yarn add -D @testing-library/jest-dom

I am having the same problem - what does “You have to install jest-dom manually.” mean? Thanks.
