adb基本命令总结（Android Debug Bridge）

adb 是PC和设备连接的桥梁，可以通过adb对devices进行相关操作

adb devices 列出你的devices

adb kill-server 杀掉adb服务（如果设备连接出问题，可尝试）

adb start-server 重启adb服务

adb shell 进入默认device的Linux shell,可以直接执行Linux命令

adb shell screenrecord /sdcard/runCase.mp4 录制视频保存，默认3min,也可以加--time-limit 60限制时间

adb install jd.apk 向设备安装app

adb pull /sdcard/runCase.mp4 c:// 把手机中文件copy到电脑

adb push C://runCase.mp4 /sdcard/ 把电脑中文件放到手机

以上就是一些基本的adb 命令

appium实现截图

由于我有webdriver 的基础，理解起来比较easy，appium截图实际是继承webdriver的

selenium 中使用的是TakesScreenShot接口getScreenShotAs方法，具体实现如下

1 /** 2      * This Method create for take screenshot 3      *  4      * @author Young 5      * @param drivername 6      * @param filename 7      */ 8     public static void snapshot(TakesScreenshot drivername, String filename) { 9         // this method will take screen shot ,require two parameters ,one is10         // driver name, another is file name11 12         String currentPath = System.getProperty("user.dir"); // get current work13                                                                 // folder14         File scrFile = drivername.getScreenshotAs(OutputType.FILE);15         // Now you can do whatever you need to do with it, for example copy16         // somewhere17         try {18             System.out.println("save snapshot path is:" + currentPath + "/"19                     + filename);20             FileUtils21                     .copyFile(scrFile, new File(currentPath + "\\" + filename));22         } catch (IOException e) {23             System.out.println("Can't save screenshot");24             e.printStackTrace();25         } finally {26             System.out.println("screen shot finished, it's in " + currentPath27                     + " folder");28         }29     }

调用： snapshot((TakesScreenshot) driver, "zhihu_showClose.png");

你可以在捕获异常的时候调用，可以实现错误截图，做测试结果分析很有效

appium清空EditText（一个坑）

在使用appium过程中，发现sendkeys和clear方法并不太好使，只好自己封装模拟手工一个一个删除

这里用到keyEvent,具体内容请参考api

要删除一段文字，该怎么做：

1. 获取文本长度

2. 移动到文本最后

3. 按下删除按钮，直到和文本一样长度

移动到文本最后： 123删除67

`public static final int`		`67`
`public static final int`		`67`

public static final int 123

实现代码如下：

/**	 * This method for delete text in textView	 * 	 * @author Young	 * @param text	 */	public void clearText(String text) {		driver.sendKeyEvent(123);		for (int i = 0; i < text.length(); i++) {			driver.sendKeyEvent(67);		}	}

整个case的代码贴一下

初始化driver，执行cmd.exe /C adb shell screenrecord /sdcard/runCase.mp4 开始录制测试视频

执行login
