Unit Testing with Jest

Help
1

I am trying to unit test with Jest.

This code works:

import {create} from "ipfs";
test("dummy",async () => {
    expect(1).toBe(1)
})

This code does not work:

import {create} from "ipfs";
test("dummy",async () => {
    await create();
    expect(1).toBe(1)
})

Jest prints this to the console multiple times:

ReferenceError: You are trying to `import` a file after the Jest environment has been torn down. From index.test.js.

          at async Promise.all (index 6)
          at async Promise.all (index 8)
          at async Promise.all (index 1)

          at async Promise.all (index 3)
          at async Promise.all (index 10)
          at async Promise.all (index 40)

The final printout is this:

Test suite failed to run

I have plenty of app code that works, just trying to start adding unit tests, but this is obviously a blocker! Any help appreciated. I could not find a solution elsewhere on the forums.
