为什么 TypeError: axios.create 不是一个函数？测试 axios GET 时

我正在尝试在 React 中测试我的 axios API 函数。

在这里发现这个问题：我如何开玩笑地测试 axios https://stackoverflow.com/questions/45016033/how-do-i-test-axios-in-jest其中指出使用axios-mock-adapter

import axios from 'axios';
import MockAdapter from 'axios-mock-adapter';
import chatbot from './chatbot';

describe('Chatbot', () => {
    it('returns data when sendMessage is called', done => {
        var mock = new MockAdapter(axios);
        const data = { response: true };
        mock.onGet('https://us-central1-hutoma-backend.cloudfunctions.net/chat').reply(200, data);

        chatbot.sendMessage(0, 'any').then(response => {
            expect(response).toEqual(data);
            done();
        });
    });
});

真正的功能：

/**
 * Retrieve all Akamai images
 * @param  {String} akamai Akamai url
 * @return {Thenable}      Resolved: Akamai images
 */
export const callGetAkamai = () =>
  makeRequest('/akamai', 'GET')
    .catch(defaultCatch('callGetAkamai'));

My test:

import axios from 'axios';
import MockAdapter from 'axios-mock-adapter';
import { callGetAkamai } from './api';

describe('GetAkamai', () => {
  it('returns data when callGetAkamai is called', (done) => {
    console.log('MockAdapter', MockAdapter);
    const mock = new MockAdapter(axios);
    // const mock = axios.create({
    //   baseURL: 'https://us-central1-hutoma-backend.cloudfunctions.net/chat/'
    // });

    const data = { response: true };
    mock.onGet('https://us-central1-hutoma-backend.cloudfunctions.net/chat').reply(200, data);

    callGetAkamai().then((response) => {
      expect(response).toEqual(data);
      done();
    });
  });
});

你在嘲笑吗axios已经？我自己也遇到过这个问题，在查看了所有错误的地方后，我意识到我已经在嘲笑了axios with jest.

将以下代码片段放入您的安装测试框架脚本文件 https://jestjs.io/docs/en/configuration.html#setuptestframeworkscriptfile-string:

const mockNoop = () => new Promise(() => {});

// Notice how `create` was not being mocked here...
jest.mock('axios', () => ({
  default: mockNoop,
  get: mockNoop,
  post: mockNoop,
  put: mockNoop,
  delete: mockNoop,
  patch: mockNoop
}));

虽然您可能可以同时执行这两项操作，但如果您使用的是axios-mock-adapter，您可能想要删除其他模拟（并跳过上面的代码片段）。
