Appium Server version：1.4.13
问题一
问题描述：发送一个非法的 xpath 请求，例如：driver.findElement(By.xpath("delay->8")).click()，导致 Appium Server 直接崩溃退出
开始以为服务端顶多抛个异常，通知用户非法指令或非法参数之类的，也不至于退出吧，自己犯的的一个低级错误无意踩中 Appium 的一个问题
Appium Server Log
error: uncaughtException: selectedNodes.slice is not a function date=Mon May 23 2016 11:10:30 GMT+0800 (CST)
问题二
问题描述：iOS 真机运行 1 个多小时，instruments 异常导致 Appium Server 退出
问题分析：是否是 app 内存泄露、溢出导致 instruments 工作异常而退出，最终导致 appium 服务的退出？

第二个问题只是推测，每次运行 1 个多小时就重现，谁比较清楚这个报错，能给个确切的结果？
每次都崩溃？
你是不是用的 GUI？ 换成命令行的吧。
#4 楼 @lylyliuyu 我是用命令行的
楼主是不是每个 case 都重新启动 App 呢？如果是的话，我之前也是因为这样，二十个 cases，在 Android 上跑完十五六个 ADB server 就挂掉了
#8 楼 @guaixiaomei 可能是一样的问题
#10 楼 @guaixiaomei 还没，我觉得这个和遍历工具本身无关，我这边 android 跑 2 个小时没问题的，基本也能排除 appium 的问题，很可能是 instrument 本身的问题吧
#12 楼 @guaixiaomei 目前我是通过设置黑名单、触发器等手段避免跳转到其他应用的
跑了一会 appium server 也会自动死掉。目前无解。
对于 appium 的 seesion 存在时间有设置的办法吗
#22 楼 @quqing 我对比了 GUI 版本和我的命令行，就差如图红框处的选项，如果勾上就 OK，不勾上就提示错误的 activity，log 如下：

请问你知道这个对应的命令行参数是什么么？我在代码里面设置了
capabilities.setCapability("StopAppOnReset", "True");
但是好像没有效果
// set up appium
File classpathRoot = new File(System.getProperty("user.dir"));
// 被测应用存放的目录
File appDir = new File(classpathRoot, CommonData.appPath);
// 被测应用的apk名字
File app = new File(appDir, CommonData.appName);
// 设置DesiredCapabilities信息
DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities.setCapability(CapabilityType.BROWSER_NAME, "");
// 以下两项为了支持中文输入
capabilities.setCapability("unicodeKeyboard", "True");
capabilities.setCapability("resetKeyboard", "True");
capabilities.setCapability("device", "Android");
// 安卓真机的信息，版本5.0.1，魅族MX5
capabilities.setCapability("deviceName", CommonData.deviceName);
capabilities.setCapability(CapabilityType.VERSION,CommonData.deviceVersion);
// 使用的是mac平台
capabilities.setCapability(CapabilityType.PLATFORM, "Mac OS X");
// 设置apk路径
capabilities.setCapability("app", app.getAbsolutePath());
// 应用的主包名
capabilities.setCapability("app-package", CommonData.appPackage);
//
capabilities.setCapability("StopAppOnReset", "True");
capabilities.setCapability("noReset", "True");
driver = new AndroidDriver<WebElement>(new URL(CommonData.serverUrl), capabilities);
我设置了 ‘capabilities.setCapability("StopAppOnReset", "True");’
但是好像没有生效，因为走到最后的 new AndroidDriver 这里的时候就提示错误了，没有等到.SplashActivity 了
#26 楼 @quqing 就是上面回复你的那段呀，在 server 里面打印出来的
