背景：在Eclipse中不能直接运行Uiautomator工程，所以每次编写一份用例都要进行手动输入命令创建build文件、ant编译文件、push文件与运行测试这四步。调试起来不仅繁琐还浪费时间。网上找到一份快速调试的代码UiAutomatorHelper，可将这几步进行简化很方便。
步骤：将UiAutomatorHelper.java放到工程目录下（与测试脚本同步目录），在测试脚本中写个main方法。然后Run as ->java application即可
1 package com.change.display; 2 3 4 import java.io.IOException; 5 6 import android.os.RemoteException; 7 8 import com.android.uiautomator.core.UiDevice; 9 import com.android.uiautomator.core.UiObject;10 import com.android.uiautomator.core.UiObjectNotFoundException;11 import com.android.uiautomator.core.UiSelector;12 import com.android.uiautomator.testrunner.UiAutomatorTestCase;13 14 public class Display extends UiAutomatorTestCase{15 public static void main(String [] arg ){16 String jarName="ChangeFont";17 String testClass="com.change.display.Display";18 String testName="test1";19 String androidId="1";20 new UiAutomatorHelper(jarName, testClass, testName, androidId); 21 }22 public void test1 () throws UiObjectNotFoundException, RemoteException, IOException{23 //Device wake up24 UiDevice.getInstance().wakeUp();25 //sleep 3s26 sleep(3000);27 //Open the settings28 Runtime.getRuntime().exec("am start -n com.android.settings/.Settings");29 //Click on display30 try{31 UiObject display = new UiObject(new UiSelector().text("显示"));32 display.click();33 sleep(3000);34 }catch(Exception e){35 e.printStackTrace();36 }37 //Select font38 UiObject fs = new UiObject(new UiSelector().text("字体大小"));39 fs.clickAndWaitForNewWindow();40 //Change font41 UiObject size = new UiObject(new UiSelector().text("超大"));42 size.click();43 //Screen shot44 sleep(3000);45 Runtime.getRuntime().exec("screencap -p /sdcard/test.png"); 46 //Enter Home interface47 sleep(3000);48 getUiDevice().pressHome(); 49 }50 }
顺带附上UiAutomatorHelper.java代码
