Android Junit单元测试 基于Uiautomator UI测试(三）

• 之前提到在androidTest中进行的是UI测试，这次使用的是Uiautomator，使用Java进行Ui测试
• 打开uiautomator viewer（sdk\tools\bin下）

• 在androidTest中创建class->UiTest
• 方法名一定要以Test开头

package com.example.adminstator.myapplication;

import android.app.Instrumentation;
import android.content.Context;
import android.os.RemoteException;
import android.support.test.InstrumentationRegistry;
import android.support.test.uiautomator.UiDevice;
import android.support.test.uiautomator.UiObject;
import android.support.test.uiautomator.UiObjectNotFoundException;
import android.support.test.uiautomator.UiSelector;
import junit.framework.TestCase;


/**

public class UiTest extends TestCase {


    public void testA() throws UiObjectNotFoundException, RemoteException {
        //获取设备
        Instrumentation instrumentation = InstrumentationRegistry.getInstrumentation();
        UiDevice uiDevice = UiDevice.getInstance(instrumentation);


        //获取上下文
        Context context = instrumentation.getContext();
//        uiDevice.click(102, 227);
        //先回到主界面
        uiDevice.pressHome();
        //获取浏览器对象，并单击
        UiObject browserObject = new UiObject(new UiSelector().text("浏览器"));
        browserObject.clickAndWaitForNewWindow();


        //获取搜索框对象，并单击
        UiObject editObject =  new UiObject(new UiSelector().className("android.widget.EditText"));
        editObject.click();
        uiDevice.pressDelete();
        editObject.setText("www.baidu.com");
        uiDevice.pressEnter();
        //等待网页
        uiDevice.sleep();
    }
}

• UiDevice类介绍

• UiDevice代表设备状态
• UiDevice功能：

• 获取设备信息：屏幕分辨率，旋转状态，亮灭屏状态等
• 操作：按键，坐标 操作，滑动，拖拽，灭屏唤醒屏幕，截图等。
• 监听器的功能

• 按键与KeyCode使用

• 手机常见按键：

• Home
• Menu
• Back
• Volume_up
• Volume_Down
• ReventApps
• Power
• Dpad //轨迹球太老旧

public void testB() throws UiObjectNotFoundException{        
       //获取UiDevice的方式        
       UiDevice uiDevice = 
       UiDevice.getInstance(InstrumentationRegistry.getInstrumentation());
       // getUiDevice().pressHome();此方法容易出现空指针异常     
       UiDevice.getInstance().pressMenu();   
}

• KEYCODE 键盘映射码：

• KeyEvent按键事件
• META Key

• 辅助功能键：ALT， SHIT， CAPS_LOCK

public void testC() throws UiObjectNotFoundException{
        //获取UiDevice的方式
        UiDevice uiDevice = UiDevice.getInstance(InstrumentationRegistry.getInstrumentation());
        //输入小写abc
        uiDevice.pressKeyCode(KeyEvent.KEYCODE_A);
        uiDevice.pressKeyCode(KeyEvent.KEYCODE_B);
         uiDevice.pressKeyCode(KeyEvent.KEYCODE_C);
        //输入大写ABC
        uiDevice.pressKeyCode(KeyEvent.KEYCODE_A,1);
        uiDevice.pressKeyCode(KeyEvent.KEYCODE_B,1);
        uiDevice.pressKeyCode(KeyEvent.KEYCODE_C,1);
    }
}
