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：
|

4
5
6
7
8
9
10
11

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：
|

4
5

7
8

|
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);
}
}
