如何在 c# 中的 selenium 中打开多个浏览器实例？

Question

我希望我的程序能够同时打开多个浏览器实例并执行操作。但我遇到了一个问题，就是所有的动作都是依次执行的。我有一个代理服务器列表和来自它们的数据，如何使多个浏览器实例同时打开并开始工作？

我听说过硒网格。一定有办法打开与我有代理一样多的选项卡，对吗？我正在尝试通过 for 来实现这一点。我的列表包含代理数据，可以方便地循环使用它们，如果您一次运行所有内容，我如何跟踪更改？我不明白....

Answer 1

不幸的是，另一个答案对我不起作用。基于对类似问题的答案，我能够配置这样的硒实例的并行运行：

List<Task> tasks = new();
foreach (var someObject in listOfObjects)
{
    tasks.Add(Class.SomeMethod(arg1, arg2, arg3));
}
await Task.WhenAll(tasks);

Answer 2

我为这个问题所做的是创建一个winform，以使用UI进行测试。然后，在单击“按钮ID”时，请调用一个函数进行我的测试。如果您像我一样（请参阅下文）进行操作，则每次点击打开一个测试实例（或者您可以将其放入循环中以根据需要打开尽可能多的时间）。关键是不要使任务运行异步或IT将等待一个测试完成，然后再打开另一个测试。这可能不是您所需要的，但这就是我能够完成它的方式。不需要代理或多个端口或任何东西。

        private void Upload_Click(object sender, EventArgs e)
        {
            Task.Run(() => TestFunction(Param1, Param2, Param3));
        }

示例函数

        public void TestFunction(Param1, Param2, Param3)
        {
            //Function to Open Browser, You can call your browser however youd like
            IWebDriver driver = InitBrowser("chrome");
            string LandingPage = "https://google.com";
            driver.Url = LandingPage;

            driver.Quit();
        }

图像中打开多个实例

您可以查看如何在下面的 。

​

    public static IWebDriver InitBrowser(string browserName)
    {
        switch (browserName)
        {
            case "chrome":
                {
                    ChromeOptions co = new ChromeOptions();
                    co.AddArguments("--incognito", "--window-size=1920,1080", "--applicationCacheDisabled", "--applicationCookiesDisabled", "--disable-plugins", "--HideCommandPromptWindow");
                    IWebDriver driver = new ChromeDriver(co);
                    return driver;
                }
        }
        return null;
    }
