[5.1] handleAction throws error in test environment using AVA

[Ethella]

Description

Mandatory info

• Are you extending internal types to enable type-free syntax with createReducer?

// If yes PASTE HERE your types.d.ts

• Did you checked compatibility notes and migration guides?

How to Reproduce

(PASTE HERE your codesandbox link)

No CodeSandbox Link

If no codesandbox, then please provide a full working code example below including actions, reducers and your custom types used in the example.

import test from 'ava';
import * as actions from '~/app/store/auth/auth.actions';
import { store } from '~/app/store';

test('initAuthState', async t => {

  await store.dispatch(
   actions.initAuthState()
});

// auth.actions.ts
export const initAuthState = createAction(actionTypes.INIT_AUTH_STATE)();

// reducer.ts
const AuthReducer = createReducer<AuthState, AuthActions>(initialState)
  .handleAction(initAuthState, () => ({ ...initialState }));

Expected behavior

Production seems to be working just fine, but not sure why the error is thrown when creating the reducer in a test environment.

Suggested solution(s)

An example of how to write tests would be helpful.
