How to open incognito/private window with Selenium WD for different browser types?

Question

I want to test my test cases in private window or incognito window.

How to do the same in various browsers:

Answer 1

In chrome you can try using -incognito command line switch in options, not sure if there will be a problem with automation extension but worth a try.

ChromeOptions options = new ChromeOptions();
options.addArguments("incognito");

For FireFox, a special flag in the profile can be used for the purpose

FirefoxProfile firefoxProfile = new FirefoxProfile();    
firefoxProfile.setPreference("browser.private.browsing.autostart",true);

For IE

setCapability(InternetExplorerDriver.IE_SWITCHES, "-private");

Answer 2

I was able to run remote IE in private mode only after following updates:

InternetExplorerOptions options = new InternetExplorerOptions()
                    .ignoreZoomSettings()
                    .useCreateProcessApiToLaunchIe()
                    .addCommandSwitches("-private");

DesiredCapabilities capabilities = DesiredCapabilities.internetExplorer();
            capabilities.setCapability("se:ieOptions", options);
return new RemoteWebDriver(url, capabilities);

All of above didn't work for RemoteWebDriver.

Answer 3

public class gettext {
  static WebDriver driver= null;

  public static void main(String args[]) throws InterruptedException {

    //for private window

    DesiredCapabilities capabilities = DesiredCapabilities.chrome();
    ChromeOptions option = new ChromeOptions();
    option.addArguments("incognito");
    capabilities.setCapability(ChromeOptions.CAPABILITY,option);
    System.setProperty("webdriver.chrome.driver", "D:\\Tools\\chromedriver.exe");       
    driver= new ChromeDriver(capabilities);

    String url = "https://www.google.com/";
    driver.manage().window().maximize();
    driver.get(url);
    driver.manage().timeouts().implicitlyWait(20,TimeUnit.SECONDS);
    gettextdata();
  } 
}
