Chrome 使用 Webdriverio chrome 分析的远程调试端口使用情况

Question

我目前正在使用 Chrome 分析 API 来获得如下代码覆盖率。

但是每当我尝试运行测试时，我都会收到以下错误:

Error: unexpected server response (404) at ClientRequest.response (/Users/svg7/projects/examples/build/js/testSuites.js:8419:16) at ClientRequest.g (events.js:291:16) at emitOne (events.js:96:13) at ClientRequest.emit (events.js:188:7) at HTTPParser.parserOnIncomingClient (_http_client.js:472:21) at HTTPParser.parserOnHeadersComplete (_http_common.js:99:23) at Socket.socketOnData (_http_client.js:361:20) at emitOne (events.js:96:13) at Socket.emit (events.js:188:7) at readableAddChunk (_stream_readable.js:176:18)

我的代码如下：

import * as fs from "fs";
import {createSession} from "chrome-debugging-client";

describe("Functional Coverage example", function() {
this.timeout(880000);
it("Get the coverage", () => {
    createSession(async (session) => {
        const api = await session.createAPIClient("localhost", 6813);
        console.dir(api);
        const tabs = await api.listTabs();
        const tab = tabs[0];
        console.log("====>");
        console.log(tab.webSocketDebuggerUrl);
        // browser.stop();
        let client = await session.openDebuggingProtocol("http://localhost:6813");
        await client.send("Profiler.enable");
        await client.send("Page.enable");
        await client.send("Profiler.startPrecisionCoverage", {callCount: true});
        await client.send("Page.navigate", {url: "https://www.microsoft.com"});
        await new Promise((resolve) => client.on("Page.loadEventFired", resolve));
        await new Promise((resolve) => setTimeout(resolve, 10000));
        let result = await 
client.send("Profiler.takePrecisionCoverage");
        fs.writeFileSync("coverage.json", JSON.stringify(result, null, 2));
    }). catch(err => {
        console.error(err);
    });
});

    after(() => {
    });
});

我正在采取的步骤：

通过./chrome --remote-debugging-port=6813;
运行测试.

我刚遇到同样的问题。似乎有一个调试器 link 按选项卡，所以只需替换 :

session.openDebuggingProtocol("http://localhost:6813")

来自

session.openDebuggingProtocol(tab.webSocketDebuggerUrl);
