What driver do I have to use to run a selenium test in c # on the Edge Chromium browser?

Question

I'm trying to launch a simple selenium test in c # with the Edge browser, but I can't. The error that indicates me is the following:

OpenQA.Selenium.DriverServiceNotFoundException: 'The file C: \ Selenium \ Drivers \ MicrosoftWebDriver.exe does not exist. The driver can be downloaded at http://go.microsoft.com/fwlink/?LinkId=619687

This is the line of code that gives me the error: driver = new EdgeDriver ("C:\\Selenium\\Drivers");

In the path C: \ Selenium \ Drivers I have the following driver: msedgedriver.exe

Downloaded from the page: https://developer.microsoft.com/en-us/microsoft-edge/tools/webdriver/

That driver corresponds to the version I have of the Edge: Microsoft Edge is up to date. Version 80.0.361.62 (Official compilation) (64 bits)

What am I doing wrong? What is my error? How do I solve it?

Answer 1

At the time of writing, the Edgedriver downloaded by the nuget package Selenium.WebDriver.MSEdgeDriver is msedgedriver.exe, but the EdgeDriver(...) constructor is looking for MicrosoftWebDriver.exe.

I figured out that you can specify the name of the exe like so:

IWebDriver driver = new EdgeDriver(
   EdgeDriverService.CreateDefaultService(".", "msedgedriver.exe"));

Hope this works for you.

What is the selenium version you're using? If you're using Selenium 4.00-alpha03 and earlier, you could refer to the following steps to automate Microsoft Edge Chromium:

• Install the C# Selenium WebDriver 3.141.0 from here.
• Download the matching version of Microsoft Edge Driver from this page.
• Example C# code:

using OpenQA.Selenium.Edge;    
using OpenQA.Selenium.Remote;   
using System.Collections.Generic;
using System.Threading;       

var service = EdgeDriverService.CreateDefaultService(@"C:\Selenium\Drivers", @"msedgedriver.exe"); 
service.UseVerboseLogging = true; 
service.UseSpecCompliantProtocol = true; 
service.Start();  
var caps = new DesiredCapabilities(new Dictionary<string, object>() 
{ 
    { "ms:edgeOptions", new Dictionary<string, object>() { 
        { "binary", @"C:\Program Files (x86)\Microsoft\Edge\Application\msedge.exe" } 
    }} 
}); 

var driver = new RemoteWebDriver(service.ServiceUrl, caps);  
driver.Navigate().GoToUrl("https://bing.com"); 
Thread.Sleep(2000);  
driver.Close(); 
service.Dispose(); 

Note: Change the paths in the code to your owns.

You need to use Selenium 4.00-alpha04 to use the browser-specific options classes when automating Edge Chromium:

• Download the .NET language binding of Selenium 4.00-alpha04 from here

• Download the matching version of Microsoft Edge Driver from this page.

• Example C# code:

using OpenQA.Selenium.Edge; 
using OpenQA.Selenium.Remote;  

EdgeOptions edgeOptions = new EdgeOptions(false);     
edgeOptions.BinaryLocation = @"C:\Program Files (x86)\Microsoft\Edge\Application\msedge.exe"; 
var msedgedriverDir = @"C:\Selenium\Drivers"; 
var msedgedriverExe = @"msedgedriver.exe"; 

var service = EdgeDriverService.CreateDefaultService(msedgedriverDir, msedgedriverExe, false); 
service.EnableVerboseLogging = true; 
var driver = new EdgeDriver(service, edgeOptions); 
driver.Navigate().GoToUrl("https://bing.com"); 
Thread.Sleep(2000); 
driver.Close();

Note: Change the paths in the code to your owns.

Answer 3

driver = new EdgeDriver ("C:\\Selenium\\Drivers\\msedgedriver.exe");

Please remove unnecessary spaces from the path and also include the .exe file in your path

Answer 4

You should not need to download msedgedriver.exe or even know where the PATH to it is.

If you are working with a team or using a build server, it is much better to use this NuGet package:

Selenium.WebDriver.MSEdgeDriver

It will download the exe for you! And you do not have to include it in source control.

These instructions tell how to use Edge/Chromium with Selenium UI Tests, but it does not mention about this very nice NuGet package!

Here is the code from the instructions on how to initialize the driver:

        var options = new EdgeOptions();
        options.UseChromium = true;
        var driver = new EdgeDriver(options);

Answer 5

Replace msedgedriver to MicrosoftWebDriver

Copy driver to the path where Edge browser is located. For example: C:\Program Files (x86)\Microsoft\Edge\Application

Then, use the Edge browser path to initialize the driver:

driver = new EdgeDriver ("C:\Program Files (x86)\Microsoft\Edge\Application");
