Question

我正在 getArticlesFromDatabase 中测试一个axios。

好像我做错了，导致控制台显示以下消息：

（node：36919）UnhandledPromiseRejectionWarning：未处理的承诺   拒绝（拒绝id：5）：这里拒绝失败：
  （节点：36919）   弃用警告：已弃用未处理的承诺拒绝。在   未来，未经处理的承诺拒绝将终止   Node.js使用非零退出代码进行处理。

如何解决？

csrfData.js

import React from 'react';
import {shallow, configure} from 'enzyme';
import Adapter from 'enzyme-adapter-react-15';
import {expect} from 'chai';    
import axios from 'axios';
import MockAdapter from 'axios-mock-adapter';

import {getArticlesFromDatabase} from '../components/common/csrfData';

configure({adapter: new Adapter()});

describe('csrfData', function () {

    it('csrfData ', function () {

        let mock = new MockAdapter(axios);
        const data = { response: true };
        mock.onGet('127.0.0.1:8000/api/articles/get-articles-list').reply(200, data);

        getArticlesFromDatabase.then(function(value) {    
            console.log('getArticlesFromDatabase:    ',value);
        });

    });

});

Answer 1

有一个适配器插件可以帮助模拟axios

https://github.com/ctimmerm/axios-mock-adapter

如果你有返回Axios实例的通用方法

，你也可以参考我的要点

即使我为此付出了很多努力。但是最终我找到了解决方案。

这里是：

    import { .. } from '../yourServices';
    jest.mock('axios');
    var axios = require('axios');
    //If you use get, post write as below, If you are using axios(config) dont need to mock below
    jest.mock('axios', () => ({ post: jest.fn(),create: jest.fn() }));

然后在您的测试中

    describe('Sample Test', () => {
        it('Should get - Test', async () => {

            const mockedResponse = Promise.resolve({
               Response data
            });

         //Make sure you mock the the functions at import (above) before using here.    
            //Post case
            axios.post.mockResolvedValue(mockedResponse);
           //Create Case
            axios.create.mockResolvedValue(mockedResponse);
           //get ....


           //If you use default axios(url, config) or axios(config)
            axios.mockResolvedValue(mockedResponse);

            //Your code
        });
});
