Selenium Chrome Mobile Emulator testing with specific phone resoultion

[Chandra Sekhar Kakarla]

I am writing selenium script for testing different mobile views,
I used below code to run the script for "Apple iPhone 5" for the instance.

static DesiredCapabilities  capabilities;
     static String deviceName;
     public static void main(String[] args) {
      //some Sample Devices. Complete list can be found here: https://code.google.com/p/chromium/codesearch#chromium/src/chrome/test/chromedriver/chrome/mobile_device_list.cc
      //pick any of the device

    //  deviceName = "Google Nexus 5";
    //  deviceName = "Samsung Galaxy S4";
    //  deviceName = "Samsung Galaxy Note 3";
    //  deviceName = "Samsung Galaxy Note II";
    //  deviceName = "Apple iPhone 4";
      deviceName = "Apple iPhone 5";
    //  deviceName = "Apple iPad 3 / 4";

      System.setProperty("webdriver.chrome.driver", "C:\\path\\to\\driver\\chromedriver.exe");

      Map<String, String> mobileEmulation = new HashMap<String, String>();
      mobileEmulation.put("deviceName", deviceName);

      Map<String, Object> chromeOptions = new HashMap<String, Object>();
      chromeOptions.put("mobileEmulation", mobileEmulation);

      capabilities = DesiredCapabilities.chrome();
      capabilities.setCapability(ChromeOptions.CAPABILITY, chromeOptions);
      WebDriver driver = new ChromeDriver(capabilities);

      driver.manage().window().maximize();
      driver.navigate().to("http://www.google.com");

     }

When I run this I am getting error like unknown error: unrecognized chrome option: mobileEmulation

Please help me to get proper reference to write selenium script for mobile emulation(mobile height and width should be changed based on device),
and let me know the issue with the existing code.

I quickly gave this a shot and I can't recreate the problem. Looks like you may be on an older version of chromedriver which doesn't know how to handle this capability. Please try again using Chromedriver v.2.21

Thanks & Regards

As Krishnan said, i tried your code and it works perfect.

In fact i worked with older version of ChromeDriver(2.16) and latest Chrome browser(49.0)

So just better check latest of these both and give a try.

Thanks,

Uday
