Mocking a module imported in a vue component with Jest

I'm having some issues processing the documentation of Jest, because I expected this code to work:

import Vue from 'vue';
import Router from '@/router/index';
import OrdersService from '@/services/orders.service';

jest.mock('@/services/orders.service');

describe('OrdersItem.vue', () => {
  beforeEach(() => {
    // mockClear does not exist
    OrdersService.mockClear();
  });

  it('should render expected list contents', () => {
    // Orders.mock is undefined 
    OrdersService.getAll.mockResolvedValue([ ... ]);
    // ...

However it does not. It fails as-if OrdersService was never mocked. I've also tried stuff like:

jest.mock('@/services/orders.service', () => jest.fn());
jest.mock('@/services/orders.service', () => { getAll: jest.fn() });

First one replaces the whole service with a mock function (I'd like to achieve that automatic mocking functionality mentioned in the docs, where all the methods from the original are auto-replaced with mock fn). Second one fails same way as the .mock call with just the module path.

What am I doing wrong here and why?

orders.service skeleton:

import axios from 'axios';
import config from '../config/config.json';
import Order from '../models/order';

class OrdersService {
  constructor(httpClient) {
    this.httpClient = httpClient;
  }

  getAll() {
      // ...
  }
}
export default new OrdersService(axios);
