Property 'toBeInTheDocument' does not exist on type 'JestMatchers<HTMLElement>'

[khairalanam]

• @testing-library/jest-dom version: 6.1.4
• node version: 18.17.1
• jest version: 29.7.0
• npm version: 10.2.0

Other dependencies:

Relevant code or config:

import { render, screen } from "@testing-library/react";
import Home from "@/app/page";

it("should have Docs text", () => {
  render(<Home />);

  const myElement = screen.getByText("Docs");

  expect(myElement).toBeInTheDocument();
});

What you did:

I was following a Next.js Testing tutorial by Dave Gray to learn more about React Testing. I followed the tutorial until the 17-minute mark where the error occurred.

What happened:

This is the error:

Reproduction:

The steps from the beginning until the 17th-minute mark of the tutorial will give the error.

Problem description:

Property 'toBeInTheDocument' does not exist on type 'JestMatchers'. It seems that it has something to do either with TypeScript, or the Nextjs 14, or with the latest release of testing-library/jest-dom

Suggested solution:

The only solution, which seems temporary, is to roll back to an older version like 5.16.5 or 5.17. This solves the problem.

For me the following seems to be solving the issue:
setupAfterEnv.ts

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

Update:

Eh maybe it is flaky because after a couple of TS server restarts now it does not work .... Anyway maybe this is not the correct solution then.

[khairalanam]

That's pretty good. It has to be added to the config file after installing the library.

[Dyn4sty]

I've come across the issue you're experiencing and I believe I have a solution that might help you.

If you add the following line to your tsconfig.json under compilerOptions:

{
  "compilerOptions": {
    // ... other options
    "types": ["@testing-library/jest-dom"],
    // ... other options
  }
}

This will inform TypeScript to include the type definitions from @testing-library/jest-dom, which should resolve the type errors you're seeing.

[khairalanam]

This too seems solid but much cleaner. Nice!

in my case replacing import with require helped (all other fixes suggested above were already implemented and didn't help)
const { expect, describe, it } = require('@jest/globals');

[wslp12]

pnpm install --save-dev "@types/jest"
i just do install types library it work for me
not any config file edit

Thanks bro it worked, none of the solutions were working

[chrisrhymes]

I have tried adding the import '@testing-library/jest-dom/jest-globals'; to the jest.setup.ts file and adding the types to the tsconfig.json file as detailed above, but I still get the type errors showing in VS Code.

Strangely, when I open the jest.setup.ts file in VS Code, the type errors suddenly disappear and everything works as expected? Am I missing a step from my configuration?

[Noyabronok]

import '@testing-library/jest-dom'; is the only thing working for me, but I have to do it in every test file 👎

[LeeBingler]

The only solution that as work with me (I'm using Nextjs 14.0.3) is to modify the tsconfig.json and add: "types": ["@testing-library/jest- to compilerOptions

[Noyabronok]

Woohoo, I got the compilerOptions: { "types": ["@testing-library/jest-dom"] } in tsconfig.json change working!

tsconfig file needed the following change:

from:

  "include": [
    "./src/**.*",
  ],

to:

  "include": [
    "./src/**/**.*",
  ],

Appears that only files at the root or src directory were having tsconfig changes applied.

This took care of VSCode error. Unfortunately I still needed import '@testing-library/jest-dom' in my jest-setup.tsx file to remove the error from test runs

[chrisrhymes]

The comment above by @Noyabronok has pointed me in the right direction. Thanks.

I had "src/**/*.test.tsx" in the "exclude" array in my tsconfig.json for some reason 🤦 .

Removing this seems to have resolved the issue in VS Code for me now.

[dtrenz]

Adding compilerOptions: { "types": ["@testing-library/jest-dom"] } in tsconfig.json didn't work for me because it overrides my existing "typeRoots".

The only solution I've found is adding import "@testing-library/jest-dom"; to every test file, which is a bummer.

---

Update: I was able to resolve this!

If, like me, you are configuring typeRoots in tsconfig.json and the above solution using the types property doesn't work for you, you can instead update typeRoots:

"typeRoots": ["node_modules/@types", "node_modules/@testing-library"]

Better is just point ts compiler to setupTests.ts file with import to @testing-library/jest-dom by adding it to tsconfig.json include option.

checkout this comment nrwl/nx#9140 (comment) btw there is no need to install @types/testing-library__jest-dom in first step

[Danielvandervelden]

So I have this import inside of my setupTests.ts:

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

And when I have the setupTests.ts files actually open in my IDE, it's all good. No complaints. Now when I close the setupTests.ts file, my IDE starts complaining that inTheDocument() doesn't exist on JestMatchers... And then when I open setupTests.ts again, it's all good and dandy. Anybody else had this problem?

[cheater]

since this is one of the main google hits, I thought I'd share what the solution is. There are two problems: 1. jest-dom 5.x doesn't have TS types and 2. expect needs to be extended.

First, we'll uninstall jest-dom and install a 4.x version:

yarn remove @testing-library/jest-dom
yarn add -D @testing-library/jest-dom@^4.2.4

You can use the analogous npm commands instead of yarn.

Then, add this to src/setupTests.ts:

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

Doing these two things alone worked for me.

BTW, I stumbled upon this while following a tutorial that was based off of create-react-app, using the command yarn create react-app myname --template typescript.

[sugubei]

// @ts-ignore 就好了

[akiik]

I just downgraded from jest-dom 6.x to 5.x and everything is green again.

[gabrielrochas]

That works for me

1. Create/update jest.setup.ts:

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

2. Update jest.config.ts:

   // ...other configs
   setupFilesAfterEnv: ['<rootDir>/jest.setup.ts'],

3. Add type definitions in tsconfig.json:

   "compilerOptions": {
      ...
      "types": ["@testing-library/jest-dom"],
      ...
   }

As this is still alive at this date i have to say what just worked for me right now.
I updated @testing-library/jest-dom to the latest and in the jest setup file instead of importing it as import '@testing-library/jest-dom/extend-expect';, I imported it now as this import '@testing-library/jest-dom/jest-globals';

The way i use the jest functions in typescript is doing explicit imports like import { describe, expect, test } from '@jest/globals'; from the also required package @jest/globals

https://jestjs.io/docs/getting-started#type-definitions
https://github.com/testing-library/jest-dom/releases/tag/v6.0.0

i couldn't get it working with @types/jest but i dont care about it, i rather use @jest/globals.

[peguerosdc]

instead of importing it as import '@testing-library/jest-dom/extend-expect';, I imported it now as this import '@testing-library/jest-dom/jest-globals';

After hours of debugging, this is what finally made the trick for me. Thanks!

@khairalanam I was taking the same course with Dave Gray and encountered the same issue. Initially, I had errors with it and expect which were also shown in the video. I resolved these errors by running npm i -D @types/jest After addressing this, I faced the exact same error as you did, and resolved it by removing extend-expect from the import statement @testing-library/jest-dom/extend-expect in jest.setup.ts file.

The reason is that @testing-library/jest-dom no longer requires a separate import of @testing-library/jest-dom/extend-expect as it might have in earlier versions. Therefore, if you are using version 6.0 or higher, you should import @testing-library/jest-dom directly, without including the extend-expect path.
