[Test Related] globalSetup is Not Working in the Configuration

[Sahil-Maiyani]

My Version: "react-scripts": "^5.0.1",

I am configuring my project for testing. I have add globalSetup flag under the jest in the package.json

"jest": {
   ..some other configs..
    "globalSetup ": "<rootDir>/src/TestSetup/MockSetup"
  }

After doing this when I run test with npm test which is eventually run react-scripts test facing below error:

Error Details (Please expand it)

react-scripts test

Out of the box, Create React App only supports overriding these Jest options:

• clearMocks
• collectCoverageFrom
• coveragePathIgnorePatterns
• coverageReporters
• coverageThreshold
• displayName
• extraGlobals
• globalSetup
• globalTeardown
• moduleNameMapper
• resetMocks
• resetModules
• restoreMocks
• snapshotSerializers
• testMatch
• transform
• transformIgnorePatterns
• watchPathIgnorePatterns.

These options in your package.json Jest configuration are not currently supported by Create React App:

• globalSetup

If you wish to override other Jest options, you need to eject from the default setup. You can do so by running npm run eject but remember that this is a one-way operation. You may also file an issue with Create React App to discuss supporting more options out of the box.

As per my research it has been fixed with: https://github.com/facebook/create-react-app/pull/5218/commits

Some other links for additional information I found while searching.

Is this a bug or am I doing anything wrong?

Please help me here. Thanks in advance.
