如何使用testcafe截取和模拟websocket请求？

npm install ws

const WebSocket = require('ws');

const wss = new WebSocket.Server({ port: 8080 });

wss.on('connection', (ws) => {
  ws.on('message', (message) => {
    // 处理接收到的WebSocket消息
    console.log('Received message:', message);

    // 模拟WebSocket响应
    ws.send('Response from server');
  });
});

import { Selector } from 'testcafe';

fixture `WebSocket Test`
    .page `http://localhost:8080`;  // 替换为你的应用程序URL

test('Test WebSocket', async t => {
    const ws = new WebSocket('ws://localhost:8080');

    ws.onopen = () => {
        // 发送模拟的WebSocket请求
        ws.send('Request from client');
    };

    ws.onmessage = (event) => {
        // 处理接收到的WebSocket响应
        console.log('Received response:', event.data);

        // 断言WebSocket响应
        await t.expect(event.data).eql('Response from server');
    };
});
