puppeteer自动化测试

jest.config.js
module.exports = {

    preset: ‘jest-puppeteer‘, //调用preset
    // globals: _.assign({}, config.get(‘e2e‘), { //这里可以注入全局变量
    //     ENV_URL: config.get(‘baseUrl‘)
    // }),
    testMatch: [‘**/test/*.test.js?(x)‘] //指定需要进行测试的文件
}

jest-puppeteer.config.js
const port = process.env.TEST_SERVER_PORT ?
    Number(process.env.TEST_SERVER_PORT) :
    4444

    // console.log(port)

process.env.TEST_SERVER_PORT = port

module.exports = {
    launch: {
        headless: process.env.CI === ‘true‘,
    },
    browserContext: process.env.INCOGNITO ? ‘incognito‘ : ‘default‘,
    server: {
        command: `cross-env PORT=${port} node test`,
        port,
        launchTimeout: 100000,
    },
}

命令行 npm run test
 "test": "cross-env INCOGNITO=true jest -c jest.config.js --notify --detectOpenHandles",

const path = require(‘path‘)
const express = require(‘express‘)

const app = express()

app.use(express.static(path.join(__dirname, ‘static‘)))
console.log(process.env.PORT)

app.listen(process.env.PORT)
