看了很多关于截屏文章。本来想着给每一个步骤截一个屏，但是这样一来存放截屏的文件夹就会非常大，所以，现在的方案是，用例运行失败之后截屏。
整个思路是：
1. 编写一个监听器RunTestListener，继承TestListenerAdapter
2. 该监听器里编辑运行失败了，执行截图操作
3. 运行配置testng.xml文件内，添加监听器
附上代码：
RunTestListener
import io.appium.java_client.AppiumDriver;
import org.apache.commons.io.FileUtils;
import org.openqa.selenium.OutputType;
import org.testng.ITestContext;
import org.testng.ITestResult;
import org.testng.TestListenerAdapter;
import java.io.File;
import java.io.IOException;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.logging.Logger;
/**
* Created by kuki_sini on 17/4/28.
*/
public class RunTestListener extends TestListenerAdapter {
private AppiumDriver driver = Driver.getDriver();
private static Logger logger = Logger.getLogger(RunTestListener.class.getName());
@Override
public void onTestFailure(ITestResult testResult) {
super.onTestFailure(testResult);
logger.info(testResult.getName() + " RunTestListener Failure");
takeScreenShot(testResult);
}
/**
* 自动截图
*
* @param testResult
*/
private void takeScreenShot(ITestResult testResult) {
System.out.println("截图");
//时间格式化
SimpleDateFormat formatter = new SimpleDateFormat("yyyyMMddHHmmss");
//获取系统时间
String currentTime = formatter.format(new Date());
//获取screenshot文件
File screenShot = driver.getScreenshotAs(OutputType.FILE);
//截图命名
String pictureName = currentTime + "_" + testResult.getName() + ".png";
File dirFile = new File(System.getProperty("user.dir") + "/ScreenShot/" + pictureName);
int i = 1;
while (dirFile.exists()) {
pictureName = currentTime + "_" + testResult.getName() + i + ".png";
dirFile = new File(System.getProperty("user.dir") + "/ScreenShot/" + pictureName);
i++;
}
//文件copy到指定文件夹
try {
FileUtils.copyFile(screenShot, dirFile);
} catch (IOException e) {
e.printStackTrace();
}
}
}
testng.xml文件，添加监听器元素<listeners>
<listener class-name="rl.utils.RunTestListener"/>
</listeners>
这里我们就是用链家 APP（简称 LJ）来做实验哈
Feature: 调试使用
Scenario: LJ启动
Given 链家APP启动
When 在首页界面上，点击`我要租房`按钮
Then 校验是否正确进入租房画面
Scenario Outline: 调试
When 选择<选项>按钮
Then 校验<校验>画面是否正确打开
Examples:
| 选项 | 校验|
| 特殊租房 | 特殊租房 |
Scenario: 进入看房履历功能
When 在下方工具栏处点击看房按钮
Scenario: 结束LJ
But LJ关闭
这样看似完了，完全没错嘛。但是，问题来了，这与我们的初衷有点不同。
上面的代码，如果某一Scenario的某一Step失败了，那就需要等到整个Feature运行完了才会开始执行截屏，而不是我们想象的那样Step运行失败了紧接着立马就截屏。
实际上，特殊租房这个功能没有，所以，在第二个Scenario他就会运行失败，理论上就需要截屏。实际上是没有的，运行结果报错了

但是如果将Scenario: 结束LJ But LJ关闭注释掉，运行没有问题，截屏功能没有问题。但是截的图却是最后一个Scenario的最后一个步骤
这个不解呀，为啥会这样呢，还望各位童鞋了帮忙看看
