appium实现截图和清空EditText

前些日子，配置好了appium测试环境，至于环境怎么搭建，参考：http://www.cnblogs.com/tobecrazy/p/4562199.html

在使用appium的过程中，发现一些appium的坑（后边会详说）。

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 is
10         // driver name, another is file name
11 
12         String currentPath = System.getProperty("user.dir"); // get current work
13                                                                 // folder
14         File scrFile = drivername.getScreenshotAs(OutputType.FILE);
15         // Now you can do whatever you need to do with it, for example copy
16         // somewhere
17         try {
18             System.out.println("save snapshot path is:" + currentPath + "/"
19                     + filename);
20             FileUtils
21                     .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 " + currentPath
27                     + " 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 http://appium.github.io/java-client/

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`	`BACKSPACE`	`67`
`public static final int`	`DEL`	`67`

public static final int KEYCODE_MOVE_END 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
