截圖操作
public static void Screenshot(AndroidDriver driver,string ScreenName)throws IOException{
//設定時間格式
SimpleDateFormat formatter=new SimpleDateFormat("yyyy-MM-dd-mm-ss");
   //生成時間戳
   String dateString =formatter.format(new Date());
   String dir_name=System.getProperty("user.dir")+"\\異常圖片";
   System.out.println("異常圖片目錄+"dir_name");
   //由於可能存在異常圖片的且當被刪除的可能，所以這邊先判斷目錄是否存在
   if(!(new File(dir_name).isDirectory()));
   {
   //判斷是否存在該目錄
   new File(dir_name).mkdir();
   }
   //呼叫方法捕捉畫面
   File screen=driver.getScreenshotAs(outputType.FILE);
   //複製檔案到指定目錄
   //圖片最後存放的路徑由 目錄：dir_name +時間戳+測試套件+測試用例+測試步驟組合生成
   system.out.println("異常圖片名稱"+dir_name+"\\"+dateString+ScreenName+".jpg");
   FileUtils.copyFile(screen,new File(dir_name+"\\"+dateString+ScreenName+".jpg"));
}

呼叫的時候一般使用try｛

swipe_1();

｝catch(Exception e){

Screenshot(driver,"Demo")

}

public static void snapshot(TakesScreenshot drivername, String filename) {

        // this method will take screen shot ,require two parameters ,one is
        // driver name, another is file name


        String currentPath = System.getProperty("user.dir"); // get current work
                                                                // folder
        File scrFile = drivername.getScreenshotAs(OutputType.FILE);
        // Now you can do whatever you need to do with it, for example copy
        // somewhere
        try {
            System.out.println("save snapshot path is:" + currentPath + "/"
                    + filename);
            FileUtils
                    .copyFile(scrFile, new File(currentPath + "\\" + filename));
        } catch (IOException e) {
            System.out.println("Can't save screenshot");
            e.printStackTrace();
        } finally {
            System.out.println("screen shot finished, it's in " + currentPath
                    + " folder");
        }
    }
