[Solved]-Unit tests fail with error "Cypress command timeout of '4000ms' exceeded."-Reactjs

With some help from the cypress community, it seems as though the react-testing-library is adding the after each hook for clean up.

https://github.com/testing-library/react-testing-library/blob/master/src/index.js

This is an async method which results in cypress giving a warning :

cypress_runner.js:85235 Cypress Warning: Cypress detected that you returned a promise in a test, but also invoked one or more cy commands inside of that promise.

I was able to prevent this addition of the afterEach and get the tests working. We can use any one of the methods given here to achieve this.
