Vue2 Jest tests failing after updating package

[MichaelAmorim4]

Hi, I have the same beforeAll and afterAll as the example tests here https://socket.io/docs/v4/testing/#example-with-jest

I am upgrading socket.io-clients package on an old vue project to "^4.5.0" from "4.1.2" and the tests now run into a timeout issue in the beforeAll function and say

Test suite failed to run
    ReferenceError: setImmediate is not defined
        at XMLHttpRequest.dispatchEvent (node_modules/xmlhttprequest-ssl/lib/XMLHttpRequest.js:628:9)
        at setState (node_modules/xmlhttprequest-ssl/lib/XMLHttpRequest.js:654:12)
        at IncomingMessage.<anonymous> (node_modules/xmlhttprequest-ssl/lib/XMLHttpRequest.js:479:13)

What is the solution to this problem? Even just creating a new file with the exact code from the example test fails with the same error.

• Worked on 4.1.2 (nothing later)
• Using @vue/vue2-jest and @vue/cli-plugin-unit-jest
• Tests exactly as they are in the example fail
