Android自动化测试中uiautomator修改uiautomatorviewer获取不到动态界面的缺陷

2022-01-26 16:33:19

在之前的第一篇文章：

android自动化测试中hierarchyviewer和uiautomatorviewer获取控件信息的方式比对（1）

我说uiautomatorviewer获取动态的界面会报错。错误如下：

今天我学习uiautomator的时候，用dumpWindowHierarchy()获得控件信息的时候，发现这个方法可以得到动态的界面信息。这就弥补了uiautomatorviewer的缺陷。下面把过程给大家贴出来。

如何编写java工程文件的信息，前辈们写了很多，我把我学习的连接放给大家。

http://blog.csdn.net/robinzhou/article/details/8447058

我捡主要的将。java代码：

package com.ibm.test;

import java.io.File;

import com.android.uiautomator.core.UiDevice;
import com.android.uiautomator.core.UiObjectNotFoundException;
import com.android.uiautomator.testrunner.UiAutomatorTestCase;

public class MyUIauto extends UiAutomatorTestCase {
	private static final String TAG = "MyUIauto";

	public void testPressHome() throws UiObjectNotFoundException {
		File file = new File("/data/local/tmp/local/tmp/qian.xml");
		UiDevice uiDevice = getUiDevice();
		//uiDevice.pressHome();
		String realPath = "qian.xml";
		uiDevice.dumpWindowHierarchy(realPath);
	}
}

我看了一下dumpWindowHierarchy的方法源码：

    public void  [More ...] dumpWindowHierarchy(String fileName) {
        AccessibilityNodeInfo root = getAutomatorBridge().getQueryController().getAccessibilityRootNode();
        if(root != null) {
            AccessibilityNodeInfoDumper.dumpWindowToFile(
                    root, new File(new File(Environment.getDataDirectory(),
                            "local/tmp"), fileName));
        }
    }

官网上的说明默认目录是/data/local/tmp目录，但从源码上可以看见它又增加了local/tmp目录。合并起来就是/data/local/tmp/local/tmp目录。这也是我起先随便建立个目录造成的错误的原因，老是报/data/local/tmp/local/tmp/下无文件的错误。后来找到源码才知道。源码网站给大家：

http://grepcode.com/file/repository.grepcode.com/java/ext/com.google.android/android/4.1.2_r1/com/android/uiautomator/core/UiDevice.java#UiDevice.dumpWindowHierarchy%28java.lang.String%29

编写完java工程以后，用ant命令生成jar包，然后把jar包push到设备上，将秒表打开。然后运行脚本，得到xml文件，抓到本地。查看xml文件如下：

所以，这个方式才是获得控件的最佳方法。
