React-scripts test command not working

Describe the bug

react-scripts test command stopped working after update to ^4.0.3 from ^3.0.0.

It shows this error on terminal:

● Validation Error:

  Watch plugin jest-watch-typeahead/filename cannot be found. Make sure the watchPlugins configuration option points to an existing node module.

  Configuration Documentation:
  https://jestjs.io/docs/configuration.html

error Command failed with exit code 1.

Nothing has changed on the code. Only react-scripts package. Tests were working fine before the update. The project is not ejected and it is not intended to be.

Did you try recovering your dependencies?

Yes, I tried. yarn version: 1.22.10

Which terms did you search for in User Guide?

I’ve search for ‘react-scripts test’ and ‘watchPlugins’ and all I found is that I need to eject the project. I don’t understand why. It was never like that. So I think that is not the solution to the problem.

Steps to reproduce

1. Open a terminal on the CRA project root
2. Run yarn
3. Run yarn test

Expected behavior

I expect tests run fine. Like before updating to ^4.0.3.

Actual behavior

react-scripts test command stops working after update react-scripts library to ^4.0.3 from ^3.0.0.

It shows this error on terminal:

● Validation Error:

  Watch plugin jest-watch-typeahead/filename cannot be found. Make sure the watchPlugins configuration option points to an existing node module.

Thank you 😄

I have had the same issue and one important thing to notice is that the newest released version of jest-watch-typeahead is now written in native ESM and will break with the following error:

Error [ERR_REQUIRE_ESM]: Must use import to load ES Module

Make sure to install the version compatible with Jest 26 e non native ESM modules.

yarn add --exact jest-watch-typeahead@0.6.5
