6.1.0 failing on "Cannot find module '@testing-library/jest-dom'"

[Andrew Busch]

• @testing-library/jest-dom version: 6.1.0
• node version: v18.13.0
• npm version: 8.19.3

Relevant code or config:

File src/setupTests.js

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

What you did:

I upgraded from 6.0.1 to 6.1.0. Rollback to 6.0.1 fixes it.

What happened:

npm run tests now returns a failure on every test:

Cannot find module '@testing-library/jest-dom' from 'src/setupTests.js' for every test run

Reproduction:

If the root cause isn't obvious, I can work on a repo with a replicable example.

Problem description:

Fails always on current version.

Suggested solution:

My guess is something in 61d17bd broke things.

In package.json
there a lines

  "main": "dist/cjs/index.js",
  "module": "dist/esm/index.js",

These files are not in package

I have fixed this in PR #523

There's a great package: https://publint.dev/ that can lint the package json for proper hybrid settings!
Might be worth adding it to them mix

I believe the problem is actually with the new version of the @adobe/css-tools package. I've submitted a PR with them: adobe/css-tools#183

Can someone who's had this issue please verify if it's working or still erroring with jest-dom 6.1.2? We've fixed all our ESM publishing issues as far as I'm aware, so it could be adobe/css-tools#183.

[Andrew Busch]

Yep working for me too, thanks all!

The v6.1.2 fixed it for me. Thank you!
