Answer 1

In my tests, I usually just mock axios like this:

import axios from "axios";

jest.mock("axios");
const mockAxios = axios as jest.Mocked;

Then in your describe block:

beforeEach(() => {
  mockAxios.request.mockImplementationOnce(
    (): Promise => Promise.resolve({ hello: "world" })
  );
});
