使用express-session对Express端点进行单元测试

npm install express express-session supertest mocha chai --save-dev

// app.js
const express = require('express');
const session = require('express-session');

const app = express();

app.use(session({
  secret: 'your-secret-key',
  resave: false,
  saveUninitialized: true
}));

// 定义路由和其他中间件...

module.exports = app;

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

const expect = chai.expect;

describe('Express Session', () => {
  it('should set and retrieve session data', (done) => {
    request(app)
      .get('/set-session')
      .expect(200)
      .end((err, res) => {
        if (err) return done(err);

        expect(res.body).to.have.property('sessionData');
        expect(res.body.sessionData).to.equal('Hello, World!');

        request(app)
          .get('/get-session')
          .expect(200)
          .end((err, res) => {
            if (err) return done(err);

            expect(res.body).to.have.property('sessionData');
            expect(res.body.sessionData).to.equal('Hello, World!');

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

npx mocha app.test.js
