Upgrading Jest to v29 - Error Test environment jest-environment-jsdom cannot be found

Question

Has anyone successfully upgraded to latest Jest version 29?
I'm receiving an error:

Error: Test environment jest-environment-jsdom cannot be found. Make sure the testEnvironment configuration option points to an existing node module.

Jest team added more descriptive error message in version 28.0.1

Error: ...
As of Jest 28 "jsdom" is no longer shipped by default, make sure to install it separately.

Installing jsdom package resolves the issue:

# npm
npm install -D jest-environment-jsdom
# yarn
yarn add -D jest-environment-jsdom

Indeed. Cf. https://jestjs.io/docs/upgrading-to-jest28 – malix May 06 '22 at 15:21

The fact that it is no longer shipped by default, does that mean that we shouldn't use it? – Jordan Jul 05 '22 at 19:43

you can also try adding it as a dev dependency: npm install -D jest-environment-jsdom – J. David Escobar Jul 23 '22 at 03:50
@J.DavidEscobar agree, edited to install as dev dependency – marko424 Jul 23 '22 at 19:57
@marko424 i don't think it's so obvious. most people come here for guidance and reason why it's separated. I'm sure everyone is capable of installing another dependency just reading the error message – Abdul Mahamaliyev Aug 14 '22 at 08:07
After installing, you need to update scripts in package.json `"test": "jest --verbose"` to make it work properly – Smack Alpha Apr 22 '23 at 18:23

@Jordan no it doesn't mean that. – vdegenne Jun 01 '23 at 17:16
