Cannot find module '@angular/core/testing' from...

Upgrading from Angular 12 to Angular 16. In the process, 100% of my tests seem to be failing. All the errors seem to signify a missing node module. I am not sure what I am missing. Any help is extremely appreciated. Thanks!



Here is my jest.config.js:

const path = require('path');

module.exports = {
preset: 'jest-preset-angular',
setupFilesAfterEnv: ['<rootDir>/setup-jest.ts'],
testEnvironment: 'jsdom',
transform: {
'^.+\\.(ts|js|html)$': 'ts-jest',
},
moduleNameMapper: {
'^@app/(.*)$': '<rootDir>/src/app/$1',
'^@environments/(.*)$': '<rootDir>/src/environments/$1',
'^@src/(.*)$': '<rootDir>/src/$1',
'^@assets/(.*)$': '<rootDir>/src/assets/$1',
'^@styles/(.*)$': '<rootDir>/src/styles/$1',
},
transformIgnorePatterns: ['node_modules/(?!.*\\.mjs$)'],
globals: {
'ts-jest': {
tsconfig: '<rootDir>/tsconfig.spec.json',
stringifyContentPathRegex: '\\.html$',
},
},
globalSetup: path.resolve(__dirname, 'jest-global-setup.js'),
resolver: path.resolve(__dirname, 'src/jest.resolver.js'),
};


I have tried using jest 28.0.0. Currently using 27.5.1 in jest-environment-jsdom, jest in my package.json
