Hide command prompt window in Selenium WebDriver .NET binding

Published: by Creative Commons Licence

As of Selenium 2.40.0[1], Selenium WebDriver's .NET binding supports hiding the command prompt window created by ChromeDriver, IEDriver or PhantomJSDriver. The following code snippets demonstrate how to achieve it in C#.

However, according to the developer[2], it is highly discouraged to use this option, because this will make it hard to debug zombie driver processes when WebDriver code exits unexpectedly. Also note that currently PhantomJSDriver has a constructor which takes in PhantomJSDriverService parameter alone, while ChromeDriver and InternetExplorerDriver don't have this constructor overload. A pull request has been made here, which will add this missing constructor overload to these two classes.

Environment Tested:
Windows 7, Selenium 2.40.0
Chrome 33 + ChromeDriver 2.9, IE 10 + IEDriver 2.40.0, PhantomJSDriver 1.9.7


var driverService = ChromeDriverService.CreateDefaultService();
driverService.HideCommandPromptWindow = true;

var driver = new ChromeDriver(driverService, new ChromeOptions());


var driverService = InternetExplorerDriverService.CreateDefaultService();
driverService.HideCommandPromptWindow = true;

var driver = new InternetExplorerDriver(driverService, new InternetExplorerOptions());


var driverService = PhantomJSDriverService.CreateDefaultService();
driverService.HideCommandPromptWindow = true;

var driver = new PhantomJSDriver(driverService);
