Jest and Angular: Cannot find module 'src/environments/environment'-CodePudding

I have Angular projects with Jest in place for unit testing. I'm trying to unit test a certain service that has environment variable as private property and if I run the test, it fails with the following information - Cannot find module 'src/environments/environment' from 'src/app/resources/services/resources.service.ts'

 FAIL  src/app/resources/services/resources.service.test.ts

● Test suite failed to run

Cannot find module 'src/environments/environment' from 'src/app/resources/services/resources.service.ts'

jest.config.ts

// require('jest-preset-angular/ngcc-jest-processor');

globalThis.ngJest = {
  skipNgcc: true,
  tsconfig: 'tsconfig.spec.json', // this is the project root tsconfig
};

/** @type {import('@jest/types').Config.InitialOptions} */
module.exports = {
  preset: 'jest-preset-angular',
  setupFiles: ['<rootDir>/src/environment/environment'],
  setupFilesAfterEnv: ['<rootDir>/setup-jest.ts'],
};

setupJest.ts

import 'jest-preset-angular/setup-jest';
import './jest-global-mocks';

Any help will be much appreciated.
