Javascript 使用create和post、jestjs模拟axios

我目前意识到，在使用

jestjs

检查api时，不应该直接通过网络请求调用api

我一直在看一些帖子+youtube教程，例如，但仍然有点困惑，现在我确定如何让它工作

我创建了一个注册api，并希望对其进行测试，在阅读了模型文档等之后。我的文件夹结构是这样的

这就是我的

base\u axios/index.js的样子，
base\u URL
就像
http://localhost:3000

const axios = require('axios');

const { BASE_URL } = require('../base');

const baseOption = {
    // without adding this, will not be able to get axios response status
    validateStatus: function (status) {
        return status >= 200 && status <= 503;
    },
    baseURL: BASE_URL,
    headers: { 'Content-Type': 'application/json' },
};

module.exports = axios.create(baseOption);

模拟/axios.js
routes/auth/register.js
我不知道调用了哪个api调用，te响应给了我
undefined
还从jest
expect（jest.fn（））获取此错误。toHaveBeenCalledWith（…expected）

提前感谢有意见和建议的人

PS

jest.config.js
您可以模拟axios及其实现，如下所示：

jest.spyOn(axios, 'post').mockImplementation();

例如：

test('calls axios for registration', async () => {
const mockDataRequest = {};
const mockPostSpy = jest
    .spyOn(axios, 'post')
    .mockImplementation(() => {
        return new Promise((resolve) => {
            return resolve({
                data: {},
            });
        });
    });

expect(mockPostSpy).toHaveBeenCalledTimes(1);

expect(mockPostSpy).toBeCalledWith(
    `/auth/register`,
    expect.objectContaining(mockDataRequest)
);

}))
 你能添加jest配置文件吗，想检查根目录的值，如这里指定的@SanketPhansekar我有一个
jest.config.js
我编辑了我的帖子
const response=wait Auth.register（）
当然会返回undefined，因为它不返回任何内容。尝试从
request.post（'/auth/register'，data）
@fubar返回承诺，但仍然没有任何结果。
const Auth = require('../../apis/auth');
const mockAxios = require('axios');

    test('calls axios for registration', async () => {
        // this should give me an error and show which api has been called
        expect(mockAxios.post).toHaveBeenCalledWith('what is the api');

        const response = await Auth.register();
        console.log(response, 'response'); // response here gives me undefined
    });

module.exports = {
  clearMocks: true,
  coverageDirectory: "coverage",

  // The test environment that will be used for testing
  testEnvironment: "node",
};

jest.spyOn(axios, 'post').mockImplementation();

test('calls axios for registration', async () => {
const mockDataRequest = {};
const mockPostSpy = jest
    .spyOn(axios, 'post')
    .mockImplementation(() => {
        return new Promise((resolve) => {
            return resolve({
                data: {},
            });
        });
    });

expect(mockPostSpy).toHaveBeenCalledTimes(1);

expect(mockPostSpy).toBeCalledWith(
    `/auth/register`,
    expect.objectContaining(mockDataRequest)
);
