Solution 2

I had this drawback utilizing angular v13 with jest v27.2.3 and tsjest v27.0.5
and my drawback was with the configuration of jest.config.ts recordsdata and what solves it for me was this configuration:

module.exports = {
  displayName: 'myApp',
  preset: '../../jest.preset.js',
  setupFilesAfterEnv: ['<rootDir>/src/test-setup.ts'],
  globals: {
    'ts-jest': {
      tsconfig: '<rootDir>/tsconfig.spec.json',
      stringifyContentPathRegex: '.(html|svg)

or to libs

module.exports = {
  displayName: 'myLib',
  preset: '../../../jest.preset.js',
  setupFilesAfterEnv: ['<rootDir>/src/test-setup.ts'],
  globals: {
    'ts-jest': svg)

},
coverageDirectory: '../../protection/apps/myapp',
remodel: js,
transformIgnorePatterns: [
'<rootDir>/node_modules/(?!lodash-es/.*)',
'<rootDir>/node_modules/(?!ng2-charts/.*)',
'^.+.js

or to libs


],
moduleNameMapper: {
'^lodash-es

or to libs


: 'lodash'
},
snapshotSerializers: [
'jest-preset-angular/build/serializers/no-ng-attributes',
'jest-preset-angular/build/serializers/ng-snapshot',
'jest-preset-angular/build/serializers/html-comment'
]
};

or to libs


}
},
coverageDirectory: '../../../protection/libs/...',
remodel: js

coverageDirectory: '../../protection/apps/myapp',

transformIgnorePatterns: [
