硒铬无法启动

Question

Running the most basic selenium test I can think of.

using System;
using Microsoft.VisualStudio.TestTools.UnitTesting;
using OpenQA.Selenium.Chrome;
using OpenQA.Selenium;
using OpenQA.Selenium.Support.UI;
using OpenQA.Selenium.Firefox;

namespace UnitTestProject1
{
    [TestClass]
    public class UnitTest1
    {
        [TestMethod]
        public void TestMethod1()
        {
            String path = @"D:\Selenium Webdrivers\ChromeDriver\";
            IWebDriver driver;
            driver = new ChromeDriver(path);
        }
    }
}

I am using,

• Chrome Version 52.0.2743.82 m
• ChromeDriver 2.22
• Selenium WebDriver 2.53.1
• Selenium WebDriver Support Classes 2.53.1
• win10 (recent upgrade)

I have tried uninstalling and reinstalling chrome and removing the user profiles.

the error I get is,

Test Name: TestMethod1 Test FullName: UnitTestProject1.UnitTest1.TestMethod1 Test Source: c:\\Users\\user\\Documents\\Visual Studio 2013\\Projects\\UnitTestProject1\\UnitTestProject1\\UnitTest1.cs : line 13 Test Outcome: Failed Test Duration: 0:00:01.3305496

Answer 1

Try throwing your chromedriver.exe in your project/solution folder and then appropriately changing your path. That should fix the issue for you.

note: FireFoxDriver works successfully because it's included in the Selenium packages, which is also within your project solution.

Answer 2

The solution is now resolved. I was not running visual studio as an administrator. Thank you for your help.
