It’s one warnings per spec file.

Jest was updated to 26 as part of the 10.1.0 migration:

    "10.1.0": {
      "version": "10.1.0-beta.0",
      "packages": {
        "jest": {
          "version": "26.2.2",
          "alwaysAddToPackageJson": false
        },
        "ts-jest": {
          "version": "26.1.4",
          "alwaysAddToPackageJson": false
        },
        "@types/jest": {
          "version": "26.0.8",
          "alwaysAddToPackageJson": false
        },
        "jest-preset-angular": {
          "version": "8.2.1",
          "alwaysAddToPackageJson": false
        },
        "babel-jest": {
          "version": "26.2.2",
          "alwaysAddToPackageJson": false
        }
      }
    }

jest.config.js

module.exports = {
	preset: '../../jest.preset.js',
	coverageDirectory: '../../coverage/frontend-libs/my-project',
	snapshotSerializers: [
		'jest-preset-angular/build/AngularNoNgAttributesSnapshotSerializer.js',
		'jest-preset-angular/build/AngularSnapshotSerializer.js',
		'jest-preset-angular/build/HTMLCommentSerializer.js',
	],
	setupFilesAfterEnv: ['<rootDir>/src/test-setup.ts'],
	globals: {
		'ts-jest': {
			tsConfig: '<rootDir>/tsconfig.spec.json',
			stringifyContentPathRegex: '\\.(html|svg)$',
			astTransformers: [
				'jest-preset-angular/build/InlineFilesTransformer',
				'jest-preset-angular/build/StripStylesTransformer',
			],
		},
	},
	displayName: 'my-project',
};

Expected Behavior

It should not output these many warnings. There is an older issue about this as well #3499 that says it should support Jest 26.

Ideally it shouldn’t warn at all.

@FrozenPandaz I think you misunderstood me. I did the migration but it didn’t take, it said successful but didn’t actually make the change.
