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

/**
     * This Method create for take screenshot
     * 
     * @author Young
     * @param drivername
     * @param filename
     */
    public static void snapshot(TakesScreenshot drivername, String filename) {
        // this method will take screen shot ,require two parameters ,one is
        // driver name, another is file name

        String currentPath = System.getProperty("user.dir"); // get current work
                                                                // folder
        File scrFile = drivername.getScreenshotAs(OutputType.FILE);
        // Now you can do whatever you need to do with it, for example copy
        // somewhere
        try {
            System.out.println("save snapshot path is:" + currentPath + "/"
                    + filename);
            FileUtils
                    .copyFile(scrFile, new File(currentPath + "\" + filename));
        } catch (IOException e) {
            System.out.println("Can't save screenshot");
            e.printStackTrace();
        } finally {
            System.out.println("screen shot finished, it's in " + currentPath
                    + " folder");
        }
    }

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
