通過以下程式碼可以啟動chrome瀏覽器中的Apple iPhone 6模擬器

System.setProperty("webdriver.chrome.driver","src/test/resources/lib/chromedriver.exe");
Map<String, String> mobileEmulation = new HashMap<String, String>();
		//mobileEmulation.put("deviceName", "Google Nexus 5");
		mobileEmulation.put("deviceName", "Apple iPhone 6");
		Map<String, Object> chromeOptions = new HashMap<String, Object>();
		chromeOptions.put("mobileEmulation", mobileEmulation);
		DesiredCapabilities capabilities = DesiredCapabilities.chrome();
		capabilities.setCapability(ChromeOptions.CAPABILITY, chromeOptions);
		driver = new ChromeDriver(capabilities);
		System.out.println(capabilities.toString());
driver.get("http://www.ctrip.com");
 

            如果模擬的情況在chrome中沒有預置，也可以自己配置，如：

Map<String, Object> deviceMetrics = new HashMap<String, Object>();
		deviceMetrics.put("width", 360);
		deviceMetrics.put("height", 640);
		deviceMetrics.put("pixelRatio", 3.0);
		Map<String, Object> mobileEmulation = new HashMap<String, Object>();

		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");

		Map<String, Object> chromeOptions = new HashMap<String, Object>();
		chromeOptions.put("mobileEmulation", mobileEmulation);
		DesiredCapabilities capabilities = DesiredCapabilities.chrome();
		capabilities.setCapability(ChromeOptions.CAPABILITY, chromeOptions);
		driver = new ChromeDriver(capabilities);
