[英]NodeJS - Error: connect ECONNREFUSED 127.0.0.1:port (chrome-remote-interface)
[英]chrome remote interface ECONNREFUSED 127.0.0.1:9222
我正在使用 Testcafe,它不直接支持訪問 Chrome 開發工具。 我的目標是切斷網絡,以便我可以在網站上看到錯誤對話框。 這是我寫的代碼。 TestCafe opens at a different url Here is the URL: http://192.168.0.123:52678/someRandomStringHere/https://abcdefgh.com/abcdefgh/
我無法為此 url 配置參數。 僅供參考,端口號更改,它不是固定的。 有人可以幫我解決這個問題。
//Performing some actions using Testcafe here
let config = {
offline: true,
latency: 100,
downloadThroughput: 750 * 1024 / 8,
uploadThroughput: 250 * 1024 / 8
};
const CDP = require('chrome-remote-interface');
const client = await CDP();
const {Network} = client;
await Promise.all([
Network.enable()
]);
Network.emulateNetworkConditions(config);
//Checking if the error is present or not in website after cutting the network

此外,在 TestCafe 存儲庫中,我們有一個模擬網絡節流的測試: https://github.com/DevExpress/testcafe/blob/61f3703d50ef8cc64331d09659837c52a9aae862/test/functional/fixtures/regression/9-testcafe. js :
import { ClientFunction } from 'testcafe';
fixture `Should reconnect with bad network conditions (GH-3929)`
.page `http://localhost:3000/fixtures/regression/gh-3929/pages/index.html`;
const getClickCount = ClientFunction(() => {
return window.clickCount;
});
test(`Click action with bad network conditions`, async t => {
const browserConnection = t.testRun.browserConnection;
const browser = browserConnection.provider.plugin.openedBrowsers[browserConnection.id];
const client = await browser.browserClient.getActiveClient();
const networkConditions = {
offline: true,
latency: 10,
downloadThroughput: 100000,
uploadThroughput: 100000
};
await client.Network.emulateNetworkConditions(networkConditions);
setTimeout(() => {
networkConditions.offline = false;
client.Network.emulateNetworkConditions(networkConditions);
}, 5000);
const expectedClickCount = 10;
for (let i = 0; i < expectedClickCount; i++)
await t.click('button');
const actualClickCount = await getClickCount();
await t.expect(actualClickCount).eql(expectedClickCount);
});
