jest throws Unknown option "reporters" with value ...

[LukasSefcik]

Current Behavior

Working with jest in nx monorepo. When running tests I got validation warning

Unknown option "reporters" with value ["default", ["/Users/sefcik/Work/azureDevOps/esw/WebApps/node_modules/jest-junit/index.js", {"outputDirectory": "test-reports", "outputName": "TESTS-components-report.xml"}]] was found.
This is probably a typing mistake. Fixing it will remove this message.

I am using jest-junit reporter version 16.0.0.

My jest.config.ts file looks like this:

export default {
  displayName: 'ssw-shared-legacy',
  preset: '../../jest.preset.js',
  setupFilesAfterEnv: ['<rootDir>/src/test-setup.ts'],
  coverageDirectory: '../../coverage/apps/ssw-shared-legacy',
  reporters: [
    'default',
    ['jest-junit', {outputDirectory: 'test-reports', outputName: 'TESTS-ssw-shared-legacy-report.xml'}],
  ],
  transform: {
    '^.+\\.(ts|mjs|js|html)$': [
      'jest-preset-angular',
      {
        tsconfig: '<rootDir>/tsconfig.spec.json',
        stringifyContentPathRegex: '\\.(html|svg)$',
      },
    ],
  },
  transformIgnorePatterns: ['node_modules/(?!.*\\.mjs$)'],
  snapshotSerializers: [
    'jest-preset-angular/build/serializers/no-ng-attributes',
    'jest-preset-angular/build/serializers/ng-snapshot',
    'jest-preset-angular/build/serializers/html-comment',
  ],
};

Expected Behavior

I would like to run test with reporters without this warning.

Thanks for reporting this!

Unfortunately, this is an issue in Jest itself, which affects multiple configuration options: jestjs/jest#13576. It seems reporters was fixed, but the change was not released for 29.x.x (jestjs/jest@04204e4).

I'm going to close this since it's an issue upstream and it's not actionable by us. Once the change is released and we add support for Jest 30, the warning will disappear.
