查找由Selenium WebDriver启动的浏览器进程的PID

问题描述

在C#中，我启动了一个浏览器进行测试，我想获取PID，以便在Winforms应用程序中可以杀死启动的所有剩余Ghost进程

In C# I start up a browser for testing, I want to get the PID so that on my winforms application I can kill any remaining ghost processes started

driver = new FirefoxDriver();

如何获取PID?

推荐答案

看起来更像是C#问题，而不是特定于硒.

Looks more like a C# question, instead of Selenium specific.

我的逻辑是，使用firefox的所有进程PID > Process.GetProcessesByName方法，然后启动FirefoxDriver，然后再次获取进程的PID，比较它们以获取刚刚启动的PID.在这种情况下，特定驱动程序已经启动了多少个进程都没有关系(例如，Chrome启动多个，Firefox仅启动一个).

My logic would be you get all process PIDs with the name firefox using Process.GetProcessesByName Method, then start your FirefoxDriver, then get the processes' PIDs again, compare them to get the PIDs just started. In this case, it doesn't matter how many processes have been started by a specific driver (For example, Chrome starts multiple, Firefox only one).

using System.Collections.Generic;
using System.Diagnostics;
using System.Linq;
using Microsoft.VisualStudio.TestTools.UnitTesting;
using OpenQA.Selenium.Firefox;

namespace TestProcess {
    [TestClass]
    public class UnitTest1 {
        [TestMethod]
        public void TestMethod1() {
            IEnumerable<int> pidsBefore = Process.GetProcessesByName("firefox").Select(p => p.Id);

            FirefoxDriver driver = new FirefoxDriver();
            IEnumerable<int> pidsAfter = Process.GetProcessesByName("firefox").Select(p => p.Id);

            IEnumerable<int> newFirefoxPids = pidsAfter.Except(pidsBefore);

            // do some stuff with PID if you want to kill them, do the following
            foreach (int pid in newFirefoxPids) {
                Process.GetProcessById(pid).Kill();
            }
        }
    }
}
