Mocking 'crypto' not working

[joshlartz]

When using @swc/jest, mocks against crypto are not working, but they do work with ts-jest.

Versions:
"@swc/core": "^1.2.186",
"@swc/jest": "^0.2.21",
"jest": "^27.5.1",
"typescript": "^4.6.4",
"ts-jest": "^27.1.5"

// crypto.ts
import { randomUUID } from 'crypto';

export const cryptoTest = () => randomUUID();


// crypto.test.ts
import { cryptoTest } from './crypto.ts';
import * as crypto from 'crypto';

jest.spyOn(crypto, 'randomUUID').mockImplementation(() => '123456');

test('should be mocked', () => expect(cryptoTest()).toEqual('123456'));

Results in:

Expected: "123456"
Received: "75852814-ebca-4080-92da-3f9db02aebf6"

I'm sorry, a duplicate of which issue? #14 didn't seem quite the same as I don't get an error; the mocking just doesn't happen.

Thank you. You're saying this is actually working correctly and ts-jest has always done it wrong? swc-project/swc#3843 (comment)
