为什么TypeError：axios.create不是函数？测试axios GET时

Why TypeError: axios.create is not a function? When testing axios GET

我正在尝试在React中测试我的axios API函数。

在这里发现了这个问题：我如何用指向axios-mock-adapter的笑话来测试axios

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();
});
});
});

/**

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

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({

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();
});
});

您是否在嘲笑axios？我自己遇到了这个问题，在所有错误的地方查看后，我意识到我已经在用jest嘲笑axios。

将以下代码段放入setupTestFrameworkScriptFile中：

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
}));

虽然您可能同时做到这两个，但是如果您使用的是axios-mock-adapter，则可能要删除其他模拟(并跳过上面的代码段)。
