Appium自动化中截图的问题

在用Appium做UI自动化过程中，大家会发现测试报告很重要，而在测试报告中截图很重要。

因为很多公司都是用Jenkins作为持续集成工具，所以要让执行自动化测试的人看明白自动化在跑什么，哪里失败了，关键节点都需要截图。

怎么做呢，目前项目中是这么实现的：

1.实现截图功能类：

public static String screenShot(ShipperAndroidEmulator ae) {
    String dir = "screenshot"; // TODO
    String time = new SimpleDateFormat("yyyyMMdd-HHmmss").format(new Date());
    String screenShotPath = dir + File.separator + time + ".png";
 
    AndroidDriver augmentedDriver = null;
    augmentedDriver = ae.getAndroid();
 
 
    try {
        File sourceFile = ((TakesScreenshot) augmentedDriver).getScreenshotAs(OutputType.FILE);
        FileUtils.copyFile(sourceFile, new File(screenShotPath));
    } catch (Exception e) {
        e.printStackTrace();
        return "Failed to screenshot";
    }
 
    return screenShotPath.replace("\", "/");
}

2.用screenShot实现错误处理类：

private void handleFailure(String notice) {
    String png = LogTools.screenShot(this);
    String log = notice + " >> capture screenshot at " + png;
    logger.error(log);
    if (GlobalSettings.baseStorageUrl.lastIndexOf("/") == GlobalSettings.baseStorageUrl.length()) {
        GlobalSettings.baseStorageUrl = GlobalSettings.baseStorageUrl.substring(0, GlobalSettings.baseStorageUrl.length() - 1);
    }
    Reporter.log(log + "<br/><img src="" + GlobalSettings.baseStorageUrl + "/" + png + "" />");
    Assert.fail(log);
}

3.对所有appium界面操作类进行处理：

public void click(By by) {
 
    expectElementExistOrNot(true, by, timeout);
    try{
        clickTheClickable(by,System.currentTimeMillis(),2500);
        handleSuccess("Succeed to click " + by);
    }catch(Exception e){
        e.printStackTrace();
        handleFailure("Failed to click " + by);
    }
    logger.info("Clicked " + by);
}

4. 不能点击时候重试点击操作

private void clickTheClickable(By byElement, long startTime, int timeOut) throws Exception {
    try {
        findElementBy(byElement).click();
    } catch (Exception e) {
        if (System.currentTimeMillis() - startTime > timeOut) {
            logger.warn(byElement+ " is unclickable");
            throw new Exception(e);
        } else {
            Thread.sleep(500);
            logger.warn(byElement + " is unclickable, try again");
            clickTheClickable(byElement, startTime, timeOut);
        }
    }
