Issue when running eciesjs from Jest.

[goncer]

I am trying to incorporate this lib into my Jest tests, but getting the following error:
Expected private key to be an Uint8Array

Error trace:

 ./node_modules/jest/bin/jest.js ts-node/register test/sequential/test.ts 
 FAIL  test/sequential/test.ts
  test string <-> buffer utils 
    ✕ should generate valid secret (4 ms)

  ● test string <-> buffer utils  › should generate valid secret

    Expected private key to be an Uint8Array

I created this small test that fails,

import { getValidSecret } from "eciesjs/dist/utils";

describe("test string <-> buffer utils ", () => {
  it("should generate valid secret", () => {
    const key = getValidSecret();
  });
});

you can run it with:
./node_modules/jest/bin/jest.js test.ts

Jest version:
"jest": "^26.6.3",

when running with mocha all good :)

./node_modules/mocha/bin/mocha -r ts-node/register test/sequential/test.ts 
  test string <-> buffer utils 
    ✔ should generate valid secret
  1 passing (9ms)

hopefully, you can help me a bit :)
Thanks!

UPDATE:
I think this is somehow reported in a lib dependency project. I'm still wondering why it works in mocha but not in JEST 🙃

hey @kigawas ,
I found a way to solve it. The issue is on Jest not exporting some globals.
jestjs/jest#4422
The issue is kindly solved by exporting some globals,
