react-dom installed, but not found. `Could not find module in path: 'react-dom/client' relative to`

Issue

Here is the Codesandbox

I want to run a rest, but the Tests tab shows this error.

Could not find module in path: 'react-dom/client' relative to
'/node_modules/@testing-library/react/dist/@testing-library/react.esm.js'

I referred to these but they did NOT solve my problem.

1. Reinstalling it in the devDependencies https://github.com/codesandbox/codesandbox-client/issues/2276
2. Turning off my UBlock origin. https://github.com/enzymejs/enzyme/issues/529
3. Trying different browsers

What should I do to successfully run this test?

Solution

This is a known issue. The answer says you need to use a Terminal to run this, which I think it means you need to run it locally.

Hey @eps1lon - Thank you for flagging this, the tests unfortunately don't work within Server sandboxes and we'll be removing them soon. To run the tests you'll need to use the terminal. Sorry for the trouble!
