如何使用Jest和Supertest清除每次测试之间的cookie？

npm install --save-dev jest supertest cookie-parser

// app.js
const express = require('express');
const cookieParser = require('cookie-parser');

const app = express();
app.use(cookieParser());

app.get('/set-cookie', (req, res) => {
  res.cookie('testCookie', 'testValue');
  res.send('Cookie set');
});

app.get('/get-cookie', (req, res) => {
  res.send(`Cookie value: ${req.cookies.testCookie}`);
});

module.exports = app;

// __tests__/app.test.js
const request = require('supertest');
const app = require('../app');

describe('Cookie Tests', () => {
  beforeEach(() => {
    // 清除所有cookie
    request(app).get('/set-cookie').expect(200);
  });

  afterEach(() => {
    // 清除所有cookie
    request(app).get('/set-cookie').expect(200);
  });

  it('should set and get a cookie', async () => {
    const res = await request(app).get('/set-cookie').expect(200);
    expect(res.text).toBe('Cookie set');

    const res2 = await request(app).get('/get-cookie').expect(200);
    expect(res2.text).toBe('Cookie value: testValue');
  });

  it('should handle multiple cookies correctly', async () => {
    // 假设有多个cookie操作
    const res = await request(app).get('/set-cookie').expect(200);
    expect(res.text).toBe('Cookie set');

    const res2 = await request(app).get('/get-cookie').expect(200);
    expect(res2.text).toBe('Cookie value: testValue');
  });
});

// __tests__/app.test.js
const request = require('supertest');
const app = require('../app');

beforeEach(() => {
  jest.resetModules();
});

describe('Cookie Tests', () => {
  it('should set and get a cookie', async () => {
    const res = await request(app).get('/set-cookie').expect(200);
    expect(res.text).toBe('Cookie set');

    const res2 = await request(app).get('/get-cookie').expect(200);
    expect(res2.text).toBe('Cookie value: testValue');
  });
});

// __tests__/app.test.js
const request = require('supertest');
const app = require('../app');

describe('Cookie Tests', () => {
  afterEach(() => {
    // 清除特定cookie
    request(app).get('/set-cookie').expect(200);
  });

  it('should set and get a cookie', async () => {
    const res = await request(app).get('/set-cookie').expect(200);
    expect(res.text).toBe('Cookie set');

    const res2 = await request(app).get('/get-cookie').expect(200);
    expect(res2.text).toBe('Cookie value: testValue');
  });
});
