在工程中编写case

1         分析Device当前界面的UI内容

在编写Case之前,需要找到界面上不同控件的id,text,class或者description等等,来定位具体的点击事件。我们可以使用uiautomatorviewer工具来分析界面的组织架构。

UiAutomator自动化测试框架介绍

2         官方用例

package com.uia.example.my;

// Import the uiautomator libraries
import com.android.uiautomator.core.UiObject;
import com.android.uiautomator.core.UiObjectNotFoundException;
import com.android.uiautomator.core.UiScrollable;
import com.android.uiautomator.core.UiSelector;
import com.android.uiautomator.testrunner.UiAutomatorTestCase;

public class LaunchSettings extends UiAutomatorTestCase {

public void testDemo() throws UiObjectNotFoundException {  
    
      // Simulate a short press on the HOME button.
      getUiDevice().pressHome();
      
      // We’re now in the home screen. Next, we want to simulate 
      // a user bringing up the All Apps screen.
      // If you use the uiautomatorviewer tool to capture a snapshot 
      // of the Home screen, notice that the All Apps button’s 
      // content-description property has the value “Apps”.
 We can 
      // use this property to create a UiSelector to find the
button. 
      UiObject allAppsButton = new UiObject(new UiSelector()
         .description("Apps"));
      
      // Simulate a click to bring up the All Apps screen.
      allAppsButton.clickAndWaitForNewWindow();
      
      // In the All Apps screen, the Settings app is located in 
      // the Apps tab. To simulate the user bringing up the Apps
tab,
      // we create a UiSelector to find a tab with the text 
      // label “Apps”.
      UiObject appsTab = new UiObject(new UiSelector()
         .text("Apps"));
      
      // Simulate a click to enter the Apps tab.
      appsTab.click();

// Next, in the apps tabs, we can simulate a user swiping
until
      // they come to the Settings app icon.  Since the
container view 
      // is scrollable, we can use a UiScrollable object.
      UiScrollable appViews = new UiScrollable(new UiSelector()
         .scrollable(true));
      
      // Set the swiping mode to horizontal (the default is
vertical)
      appViews.setAsHorizontalList();
      
      // Create a UiSelector to find the Settings app and simulate
     
      // a user click to launch the app. 
      UiObject settingsApp = appViews.getChildByText(new
UiSelector()
       
 .className(android.widget.TextView.class.getName()), 
         "Settings");
      settingsApp.clickAndWaitForNewWindow();
      
      // Validate that the package name is the expected one
      UiObject settingsValidation = new UiObject(new
UiSelector()
       
 .packageName("com.android.settings"));
      assertTrue("Unable to detect Settings", 
         settingsValidation.exists());   
  }   
}

Build工程

1        
产生build工程所需要的配置文件

<android-sdk>/tools/android create
uitest-project -n <name> -t 1 -p <path>

name:
build jar文件的名字

1: 使用命令android list可以查看

UiAutomator自动化测试框架介绍

path:
工程目录

2        
build工程jar文件

2.1配置文件创建完成后,刷新工程目录,将会产生三个文件:build.xml、local.properties和project.properties

UiAutomator自动化测试框架介绍

2.2    打开build.xml,将default值改成build,如下图

UiAutomator自动化测试框架介绍

2.3    build工程

UiAutomator自动化测试框架介绍

运行工程

1        
导入

将build好的jar文件,push到手机目录/data/local/tmp/下

2        
运行命令

adb shell uiautomator runtest
LaunchSettings.jar(build出来的文件) -c com.uia.example.my.LaunchSettings(class名)

如果想要运行class类里具体的方法,可以在类后面加上#方法名即可

如果想手机单独运行程序,不受数据线的约束,可以使用--nohup

UiAutomator自动化测试框架介绍

Public Methods

abstract boolean

checkForCondition()

抽象方法,在监听程序中要实现此方法

The testing framework calls this handler method automatically when the framework is unable to find a match using the UiSelector.

监听器要在中断代码之前运行,我们首先要注册一个监听器,然后运行。注册监听器的方法,在UiDevice的API中有介绍,

void

registerWatcher(String name, UiWatcher watcher)

注册一个监听器,当前指定动作被打断的

时候,处理中断异常

Registers a UiWatcher to run automatically when the testing framework is unable to find a match using a UiSelector.

注册监听器的结构方法如下:

UiDevice.getInstance().registerWatcher(“register watcher method”, new UiWatcher(){

Public boolean checkForCondition{

//在此方法体内定义监听的方法

}

});

编写用例的注意事项

1.每一个类都要继承UiAutomatorTestCase

UiAutomator自动化测试框架介绍

2.最好在每个类里都定义setUp和tearDown方法,用于初始化(最好都以Home界面为测试开始点)和结束测试(最好也以Home界面为测试结束点)

UiAutomator自动化测试框架介绍

3.因为此套测试框架式继承与Junit3的,所以每个方法最好都要以test开头,运行单个类时,程序会run以test开头的方法。当然这不是强制的,也可以以#方法run用例。
