如何在TypeScript中使用Mocha模拟axios依赖关系？

如何解决如何在TypeScript中使用Mocha模拟axios依赖关系？

这是我的示例src / main.ts文件

import axios from 'axios';
export async function main() {
     const URL = 'test url';
     const secretKey = 'Test key'
     const response = await axios.get(URL,{
        headers: { 'Content-Type': 'application/json','KEY': secretKey },});

我想使用mocha将测试用例写到spec / test.ts文件中。有人可以告诉我如何为axios依赖项创建模拟和存根。

解决方法

对于typetript中的模拟/存根轴，我建议axios-mock-adapter，对于期望函数chai

这里是如何执行此操作的示例

request.ts

import axios from 'axios';

const apiConfig = {
    returnRejectedPromiseOnError: true,timeout: 30000,headers: {
        common: {
            'Content-Type': 'application/json','Accept': 'application/json',},};

const request = axios.create(apiConfig);
export default request;

main.ts

import request from './request';

export const URL = 'https://httpbin.org/get';
export const secretKey = 'secret_key';

export async function main() {

    const response = await request.get(URL,{
        headers: {
            KEY: secretKey,});

    // response logic

    return response;
}

main.spec.ts

import MockAdapter from 'axios-mock-adapter';
import { expect } from 'chai';

import request from './request';
import { main,URL,secretKey } from './main';


describe('Request test',() => {
    let stub: MockAdapter;
    const receivedData = { data: 'data' };

    before(() => {
        stub = new MockAdapter(request);
        stub.onGet(URL,{
            headers: {
                KEY: secretKey,}).replyOnce(200,receivedData);
        // replyOnce if you assume that your code sends a single request
    });

    it('test',async () => {
        const response = await main();

        expect(response.status).to.be.equal(200);
        expect(response.data).to.be.deep.equal(receivedData);
    });

    after(() => {
        stub.restore();
    });
});
