Typescript Jest 说我想要模拟的类型上不存在模拟或模拟返回值

这是我想测试的一个类：

//Request.js
import axios, {AxiosInstance} from 'axios';
import config from './config';

const axiosSingleton: AxiosInstance = axios.create({
  baseURL: 'http://localhost:8080',
});

export default class Request {
  public async get<$ResponseType = any>(url: string): Promise<void> {
    const response = await axiosSingleton.get(url);
    return response.data;
  }
}

当我尝试通过创建测试文件来测试这一点时，我不确定如何模拟 axios。我尝试了很多方法，包括间谍和自动模拟。但它们似乎不起作用。这是测试文件的一个版本，我不明白为什么它不起作用

// Request.test.js
import axios from 'axios';
import Request from './Request';

interface ITestResponseDataType {
  value: string
}

jest.mock('axios');

describe('Request Tests', () => {
  it('should call axios get with the right relativeUrl', async () => {
    const getMock = jest.fn();

    axios.create.mockReturnValue({
      get: getMock
    });

    getMock.mockResolvedValue({
      value: 'value'
    });

    const data = await new Request().get<ITestResponseDataType>('/testUrl');
    expect(getMock.mock.calls.length).toEqual(1);
    expect(data).toEqual({
      value: 'value'
    });
  });
});

当我尝试运行测试时出现的错误是 -

 TypeScript diagnostics (customize using `[jest-config].globals.ts-jest.diagnostics` option):
    src/common/api/Request.test.ts:15:18 - error TS2339: Property 'mockReturnValue' does not exist on type '(config?: AxiosRequestConfig | undefined) => AxiosInstance'.

    15     axios.create.mockReturnValue({

这个错误是有道理的，因为 axios 中为 axios.create 定义的类型不应该允许在 .create 上调用 .mockReturnValue。那么我如何告诉 typescript jest 已经进入并修改了它呢？

将模拟方法转换为jest.Mock, ie

import axios from "axios"
import Request from "./Request";

// Create an Axios mock
// Don't worry about the order, Jest will hoist this above the imports
// See https://jestjs.io/docs/manual-mocks#using-with-es-module-imports
jest.mock("axios", () => ({
  create: jest.fn()
}))

// Customise the `create` mock method
(axios.create as jest.Mock).mockReturnValue({
  get: getMock
})
