How to get C# to initialize geckodriver

Question

I cannot find any implementations to get geckodriver to run my tests on FF for my C# solution, so I am reaching out to see what solutions you guys might have.

I have tried these two:

FirefoxDriverService service = FirefoxDriverService.CreateDefaultService();
                    service.FirefoxBinaryPath = @"C:\Program Files (x86)\Mozilla Firefox\firefox.exe";
                    FirefoxDriver driver = new FirefoxDriver(service);

This fails with the message "The type or namespace name 'FirefoxDriverService' could not be found (are you missing a using directive or an assembly reference?)"

System.Environment.SetEnvironmentVariable("webdriver.gecko.driver", "C:\\Selenium\\geckodriver.exe");
                    var _driver = new FirefoxDriver();

This fails the test claiming that it is unable to initialize the firefoxdriver.

FF version #:49.0.2

GeckoDriver version #: 0.11.1

Answer 1

I found the solution, by updating to the latest version of Webdriver and Webdriver.support my first method of:

FirefoxDriverService service = FirefoxDriverService.CreateDefaultService();
                    service.FirefoxBinaryPath = @"C:\Program Files (x86)\Mozilla Firefox\firefox.exe";
                    FirefoxDriver driver = new FirefoxDriver(service);

Worked without issue.

I had the same issue. Specifying the geckodriver.exe path when creating the driver service solved the problem for me.

So assuming your geckodriver.exe is located in "C:\Selenium\geckodriver.exe", you could also write:

// Notice the path argument here
FirefoxDriverService service = FirefoxDriverService.CreateDefaultService(@"C:\Selenium");
service.FirefoxBinaryPath = @"C:\Program Files (x86)\Mozilla Firefox\firefox.exe";
FirefoxDriver driver = new FirefoxDriver(service);
