Cannot run tests after updating to React v17

[VanTigranyan]

Hey Everyone. I have updated the react version and react-scripts version. Also used react-codemod to remove React imports, which are redundant if you use react v17. The thing is, after updating the application runs without any problem but the tests fail, throwing reference error React is not defined. I have tried to search info by myself and found nothing. Can someone help me with this? I am out of solutions.

This is most likely the same as testing-library/react-testing-library#810 which has the solution testing-library/react-testing-library#810 (comment)
