@JLHwung Are you sure jest.getVersion is supposed to exist? It's not documented at https://jestjs.io/docs/jest-object 🤔

It's not a thing - to get the version you'll need to parse jest/package.json (keeping the node version check but adjusting to node 10 seems easier, tho)

Thanks!

Ah jest.getVersion does not exist in Jest 24.

It does exist in Jest 28:

https://github.com/facebook/jest/blob/8f9b812faf8e4d241d560a8574f0c6ed20a89365/packages/jest/src/index.ts#L11

Ah!

That's import {getVersion} from 'jest', not the jest "global" (module scoped)

The flaky failing e2e test is because receiveMessageOnPort in @babel/eslint-parser sometimes returns undefined, even if we only ever wake the main thread after posting an object on the port. This looks like a Node.js bug 😕

Ok it passed now 🤷
