Android UiAutomator - CTS Frame

　　使用UiAutomator进行UI自动化测试后，生成的测试结果并不是很美观。为了生成一份好看的测试结果(报告)，本文将使用CTS框架，当然也可以自己编写一份测试报告框架(如：生成html，excel报告)。

一、环境搭建（这里就不再重复，可以去看CTS Test）

JDK，SDK，android-cts，run.bat

配置好环境变量下载完资源后。将android-cts复制到SDK下,并且在该目录下创建一个run.bat文件。代码如下：

@echo off
set CTS_ROOT=%~dp0
set JAR_DIR=%CTS_ROOT%android-cts\tools
set JAR_PATH=%JAR_DIR%\cts-tradefed.jar;%JAR_DIR%\ddmlib-prebuilt.jar;%JAR_DIR%\hosttestlib.jar;%JAR_DIR%\junit.jar;%JAR_DIR%\tradefed-prebuilt.jar
java -cp %JAR_PATH% -DCTS_ROOT=%CTS_ROOT% com.android.cts.tradefed.command.CtsConsole

注：这里使用的android-cts为4.4的(是使用Eclipse编写UiAutomator1的脚本Ant编译生成jar文件)。经实践使用6.0或7.1的cts框架运行时会报错(要使用android studio 编写UiAutomator2的脚本gradle进行编译生成apk文件)。

二、编写测试脚本并编译成jar包(直接运行会在工程bin目录下生成jar包)

package com.change.display;

import java.io.File;
import java.io.IOException;
import com.android.uiautomator.core.UiDevice;
import com.android.uiautomator.core.UiObject;
import com.android.uiautomator.core.UiObjectNotFoundException;
import com.android.uiautomator.core.UiSelector;
import com.android.uiautomator.testrunner.UiAutomatorTestCase;

public class Display extends UiAutomatorTestCase{
    //Quick Debugging
    public static void main(String [] args){
        String jarName="ChangeFontTest";
        String testClass="com.change.display.Display";
        String testName="testChangeFont";
        String androidId="1";
        new UiAutomatorHelper(jarName, testClass, testName, androidId);
    }

    //RUN CTS
    /*public static void main (String [] args){
         String workspace="E:\\adt\\workspace\\AutoTest";
         String className="com.change.display.Display";
         String jarName="ChangeFontTest";
         String androidId="1";
         String sdkPath="E:\\adt\\sdk";
         CtsHelper ch = new CtsHelper(workspace,className,jarName,androidId,sdkPath);
         //若需指定设备运行，则需要填写
         ch.setDevices("NEXUS0FA9F615");
         ch.runTest();
    }*/

    public void testChangeFont () throws Throwable{
        UiDevice device = UiDevice.getInstance();
        try {
            //Device wake up
            device.wakeUp();
            //sleep 3s
            sleep(3000);
            //Open the settings
            Runtime.getRuntime().exec("am start -n com.android.settings/.Settings");
            //Click on display
            UiObject display = new UiObject(new UiSelector().text("显示"));
            display.click();
            sleep(3000);
            //Select font
            UiObject fontSize = new UiObject(new UiSelector().text("字体大小"));
            fontSize.clickAndWaitForNewWindow();
            //Change font
            new UiObject(new UiSelector().text("超大")).click();
            //Screen shot
            sleep(3000);
            device.takeScreenshot(new File("/sdcard/test1.png"));
            sleep(2000);
        } catch (IOException e) {
            e.printStackTrace();
            throw new Exception();
        } catch (UiObjectNotFoundException e) {
            e.printStackTrace();
            throw new Exception();
        }finally{
            device.pressBack();
            sleep(2000);
            device.pressBack();
            sleep(2000);
            device.pressHome();
            sleep(2000);
        }
    }
}

编写好的脚本：

packageName：com.change.display

Class：Display

Method：testChangeFont

jarPackageName：ChangeFontTest

三、编写测试计划和配置文件

注：如果要看起来方便的话。可以在android-cts\repository\plans中删除全部计划，在android-cts\repository\testcases中删除删除所有内容，但必须保留TestDeviceSetup.apk

　　1、将ChangeFontTest.jar包放到android-cts\repository\testcases目录下。

　　2、且在该目录下编写ChangeFontTest.xml配置文件:

<?xml version="1.0" encoding="UTF-8"?>
<TestPackage appPackageName="com.change.display" name="ChangeFontTest" testType="uiAutomator" jarPath="ChangeFontTest.jar" version="1.0">
     <TestSuite name="com">
          <TestSuite name="change">
               <TestSuite name="display">
                    <TestCase name="Display">
                         <Test name="testChangeFont" />
                    </TestCase>
               </TestSuite>
          </TestSuite>
     </TestSuite>
</TestPackage>

　　3、在android-cts\repository\plans 文件中编写planName.xml计划文件（可随意命名）

<?xml version="1.0" encoding="UTF-8"?>
<TestPlan version="1.0">
    <Entry uri="com.change.display"/>
</TestPlan>

四、使用CTS框架运行测试jar包，并生成报告

运行run.bat文件进入CTS控制台，输入命令：run cts --plan [planName]

这里贴出一份报告：

 五、使用CtsHelper.java和UiAutomatorHelper.java在工程中直接运行生成报告

　　将CtsHelper.java和UiAutomatorHelper.java直接复制到工程目录下（放到com.change.display包下，与测试类同一目录下）。这时需要在Display测试类中将Quick Debugging部分注释掉，使用RUN CTS部分。根据个人的情况更改workspace，clasName，jarName，androidId，sdkPath以及setDevice（adb devices查询的序列号）。

　　以下是CtsHelper.java和UiAutomatorHelper.java代码：(源出处)

package com.change.display;

=================================================================================

CTS 7.0以上使用CTS框架进行测试

下载7.1r5_arm，保留7.1r5_arm\android-cts\testcases目录下的：CtsDeviceInfo.apk、CtsPreconditions.apk、cts.dynamic

1、将工程下的\build\outputs\apk下编译的apk(例:clock-debug.apk) 复制到 testcases目录。

2、编写配置文件：(不同的apk需要修改"test-file-name"和"package"对应的value)[clockTestCase.config]

<?xml version="1.0" encoding="utf-8"?>

-->
<configuration description="Config for CTS test cases">
     <target_preparer class="com.android.compatibility.common.tradefed.targetprep.ApkInstaller">
         <option name="cleanup-apks" value="true" />
         <option name="test-file-name" value="clock-debug.apk" />
      </target_preparer>
      <test class="com.android.tradefed.testtype.AndroidJUnitTest" >
          <option name="package" value="com.android.clock" />
      </test>
</configuration>

注意：在跑用例的时候，出现org.junit.runners.model.TestTimedOutException: test timed out after 6000000 milliseconds报错情况;需要在配置文件中添加延迟时间。在test标签中加入延迟的时间

<option name="test-timeout" value="6000000" />

<option name="shell-timeout" value="12000000"/>

3、编写运行CTS文件：

@echo off
set CTS_ROOT=%~dp0
set JAR_DIR=%CTS_ROOT%android-cts\tools
set JAR_PATH=%JAR_DIR%\cts-tradefed.jar;%JAR_DIR%\tradefed-prebuilt.jar;%JAR_DIR%\hosttestlib.jar;%JAR_DIR%\compatibility-host-util.jar
java -cp %JAR_PATH% -DCTS_ROOT=%CTS_ROOT% com.android.compatibility.common.tradefed.command.CompatibilityConsole run cts -a arm64-v8a --skip-preconditions

注意：使用CTS框架时，buildapk需要在AndroidManifest.xml配置文件中加入

<instrumentation
     android:name="android.support.test.runner.AndroidJUnitRunner"
     android:targetPackage="com.android.clock " >
</instrumentation>
