3. 完成以上兩步，差不多把所需的東西準備好了，接下來需要一步步開工了。首先，把底層框架中啟動和停止server的代碼修改為新的
1.0中需要啟動server才能運行，而在2.0中如果不通過Remote來運行的話是不需要啟動server的，這里提到的啟動實際是實例化過程，這中間會啟動瀏覽器，停止時會釋放資源并關閉瀏覽器。
protected static void startdriver() {
if (driver == null ){
try {
driver = DriverInstance.createInstance();
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
private static void stopDriver() {
//stop driver;
if (driver != null) {
driver.quit();
if ( browser == "Firefox") {
closeFireFox();
} else if (browser == "Chrome") {
closeChromeDriver();
}
}
}
