Using different emulators with Chrome in C#

Hi guys, Today I will post a sample code that you can use to test different screens/mobile devices/browsers using Google Chrome browser with C#. You will need change the bold words for the devices and sizes that you want to simulate.

private static ChromeOpt SetCapabilities()
Map chromeOptions = new HashMap();

DesiredCapabilities capabilities =;  capabilities.setCapability(ChromeOptions.CAPABILITY, chromeOptions);

switch (whichCase) {

case "byDevice":
Map mobileEmulation = new HashMap();
mobileEmulation.put("deviceName", "Apple iPhone 4"); //Should be the same name showing in the Chrome Device Emulator
chromeOptions.put("mobileEmulation", mobileEmulation);

case "CustomScreen":
Map deviceMetrics = new HashMap();
deviceMetrics.put("width", 900);
deviceMetrics.put("height", 600);
deviceMetrics.put("pixelRatio", 3.0);

Map mobileEmulation = new HashMap();
mobileEmulation.put("deviceMetrics", deviceMetrics);
mobileEmulation.put("userAgent", "Mozilla/5.0 (Linux; Android 4.2.1; en-us; Nexus 5 Build/JOP40D) AppleWebKit/535.19 (KHTML, like Gecko) Chrome/18.0.1025.166 Mobile Safari/535.19");
chromeOptions.put("mobileEmulation", mobileEmulation);



IWebDriver driver =new ChromeDriver(capabilities);
return driver;
