I have a strange problem with testing redux middleware when it comes to mocking createAsyncThunk which really drives me crazy.

I have the following code that is included setupFiles list in jest.config.js

import { createAction } from "@reduxjs/toolkit";

jest.doMock("@reduxjs/toolkit", () => ({
  ...jest.requireActual("@reduxjs/toolkit"),
  createAsyncThunk: jest.fn((name) => {
    const thunkAction = jest
      .requireActual("@reduxjs/toolkit")
      .createAsyncThunk(name, () => {});
    const action = createAction(name);
    (action as any).pending = thunkAction.pending;
    (action as any).fulfilled = thunkAction.fulfilled;
    (action as any).rejected = thunkAction.rejected;
    (action as any).typePrefix = name;
    return action;
  }),
}));

It works well with @reduxjs/toolkit v1.7.2, but if I upgrade to the next version (v1.8) or any subsequent versions, the middleware picks up the actual version of createAsyncThunk rather than mocked version. I went through the difference between the versions, but did not see anything relevant at all.

I apologize if I did not provide enough info, feel free to point out and I will add it. Also, I am happy at this point to hear any ideas even if you don’t have the answer.
