selenium使用谷歌浏览器自带手机模拟器运行H5网页

背景：最开始用手机模拟H5页面跑自动化，发现经常因为app连接或者网络原因等一系列情况，导致M版（H5页面）用例跑不通，想通过浏览器自带的手机模拟器运行，保证稳定性

浏览器自带的模拟器如下图：

代码实现逻辑

public class runtest {
    WebDriver driver;
    @BeforeClass
    public void beforeClass(){
        System.setProperty("webdriver.chrome.driver", "resources/chromedriver.exe");
        Map<String, String> mobileEmulation = new HashMap<String, String>();
        //设置设备,例如:Google Nexus 7/Apple iPhone 6
        //mobileEmulation.put("deviceName", "Google Nexus 7");
        mobileEmulation.put("deviceName", "Apple iPhone 6 Plus");   //这里是要使用的模拟器名称，就是浏览器中模拟器中的顶部型号
        Map<String, Object> chromeOptions = new HashMap<String, Object>();
        chromeOptions.put("mobileEmulation", mobileEmulation);
        DesiredCapabilities capabilities = DesiredCapabilities.chrome();
        capabilities.setCapability(ChromeOptions.CAPABILITY, chromeOptions);
        try {
            System.out.println("开始启动driver~~~");
            driver = new ChromeDriver(capabilities);
            System.out.println("启动driver成功~~~");
        } catch (Exception e) {
            System.out.println("启动driver失败~~~");
            System.out.println(e.getMessage());
        }
    }

    @Test
    public void run(){
        driver.get("http://m.baidu.com/");
        System.out.println("使用浏览器，进入到了百度页面");
    }

效果如图：
