篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了Uiautomator1.0与Uiautomator2.0测试项目搭建与运行原理相关的知识，希望对你有一定的参考价值。
Uiautomator是android原生测试框架，可以用于白盒接口测试也可以用于UI自动化测试，Uiautomator分1.0版本与2.0版本，它们都是基于UiAutomation的测试框架，都是通过UiAutomation的接口操作设备， 1.0权限更高，运行更灵活，2.0针对app定制化更高，在同进程内运行，可以获取被测app的运行数据，具体选用哪个框架还是根据业务场景灵活选择。
本文介绍内容：
1、AndroidStudio基于ant编译Uiautomator1.0jar包
2、Uiautomator1.0的便捷构建
3、Uiautomator1.0执行流程解析
4、模拟Uiautomator实现测试服务
| uiautomator1.0 | uiautomator2.0 | |
|---|---|---|
| 工程差异 | 基于Java的测试工程 | 基于app的测试框架，运行在目标app的进程内 |
| 构建差异 | 项目基于ant编译jar包，需要借助sdk/tools/工具生成build文件 | AndroidStudio gradle进行管理，内置编译及执行任务 |
| 运行差异 | 通过uiautomator命令执行，测试脚本进程为shell进程，进程名为uiautomator | 项目通过am命令启动执行，脚本进程为app进程，进程名为包名 |
| 权限差异 | 测试脚本拥有shell权限 | 与目标app具有相同权限 |
| 测试目标 | 可跨进程测试 | 可跨进程测试 |
| 运行条件 | shell执行，可独立运行 | shell执行，必须安装脚本应用和被测应用 |
| 数据 | 无法获取被测应用内运行数据 | 非跨进程测试情况下，可以获取被测app的运行数据 |
一、AndroidStudio基于ant编译Uiautomator1.0 jar包
uiautomator1.0是基于Java的测试框架，它通过junit和uiautomator框架执行Java测试用例，但是自从uiautomator2.0发布以后，官方不再维护uiautomator1.0的构建。目前无法直接通过Android
Studio创建uiautomator1.0测试项目，本节介绍通过AndroidStudio工具构建Uiautomator1.0 jar文件。
构建项目工程
1、AndroidStudio新构建一普通项目
2、导入依赖包
dependencies {
//uiautomator & junit测试框架，系统内部已集成，不需打包到程序。
compileOnly 'uiautomator:uiautomator:1.0'
compileOnly 'junit:junit:3.8'
}3、创建测试类
package com.android.demo.uiautomator1;
import com.android.uiautomator.testrunner.UiAutomatorTestCase;
public class MainTest extends UiAutomatorTestCase {
public void testMain(){
System.out.println("=======testMain=======>>>");
}
public void testMain2(){
System.out.println("=======testMain2=======>>>");
}
}SDK支持ant编译配置
Android最新SDK已去除ant编译工具支持，如果需要通过ant构建uiautomator1.0测试包那么就需要下载以前的sdk-tools，并将该文件复制到本机sdk中。
各平台下载地址：
Windows sdkTools
Mac sdkTools
Linux sdkTools
根据系统版本下载对应的sdkTools，下载后解压获取tools文件夹，并将tools/文件夹下所有内容复制到本机/sdk/tools/路径下。
根据项目生成build.xml
1、打开控制台，切换到/sdk/tools/路径下
2、执行命令
//projectPath 为项目的绝对路径
//uiautomatorTest为项目名，打包后的jar包名字
./android create uitest-project -n uiautomatorTest -t "android-29" -p projectPath3、打开项目，在项目路径下已生成 [build.xml]文件，打开[build.xml]文件，找到如下代码，并注视。
<!-- <property file="local.properties" />-->AndroidStudio 导入ant任务，并构建
1、打开当前module的Gradle文件，写入如下代码，然后构建一下gradle，在moduleName->Tasks->other下会列出ant任务
ant.importBuild('build.xml') {
antTargetName ->
'ant-' + antTargetName
}2、点击[ant-build]即可执行构建任务，等待执行结束后在[module/bin]路径下会生成对应的Apk文件。
?? 如果构建过程中报 check-env 错误，是因为sdk-tools 不支持ant编译导致的，需要同步一下sdk-tools
执行测试用例
adb push jarFile /data/local/tmp/
jarFile=data/local/tmp/test.jar
mainClass=com.uiautomator.test.MainTest
uiautomator runtest jarFile -c mainClass二、Uiautomator1.0 的便捷构建
基于ant的Uiautomator1.0 jar包构建是比较麻烦的，并且sdk-tools必须要支持ant编译。那么jar包的组成部分是什么？
通过解压Uiautomator1.0 jar文件，发现jar包主要由.dex文件和META-INF构成，Android 应用apk文件内也包含着两个文件，所以是可以把Uiautomator1.0源码写在普通Android项目中，并用.apk文件替换.jar文件执行测试脚本。
jar包文件构成
apk文件构成
构建apk
执行下图Gradle任务，获取打包apk文件
任务执行完毕可以得到apk打包文件
执行脚本
//将构建的apk文件推送到设备中
adb push apkFile /data/local/tmp/test.apk
//定义脚本执行文件和入口类
jarFile=data/local/tmp/test.apk
mainClass=com.uiautomator.test.MainTest
//通过命令执行测试脚本
uiautomator runtest jarFile -c mainClass三、Uiautomator1.0执行流程解析
下面通过uiautomator 命令为入口了解uiautomator1.0测试服务是如何运行的，uiautomator进程是如何初始化的。
Uiautomator1.0 执行命令结构如下：
uiautomator runtest jarFile -c mainClassuiautomator脚本源码则是一个shell脚本，通过 app_process命令加载类com.android.commands.uiautomator.Launcher
CLASSPATH=${CLASSPATH}:${jars}
export CLASSPATH
exec app_process ${base}/bin com.android.commands.uiautomator.Launcher ${args}Launcher作为uiautomator进程的入口，解析参数并调用RunTestCommand的run方法
public class Launcher {
//uiautomator进程真正执行入口
public static void main(String[] args) {
Process.setArgV0("uiautomator");//ps查看的进程名
if (args.length >= 1) {
//args[0] 对应的命令行参数为 “runtest”，查找名为“runtest”的服务est“
Command command = findCommand(args[0]);
if (command != null) {
String[] args2 = {};
if (args.length > 1) {
// consume the first arg
args2 = Arrays.copyOfRange(args, 1, args.length);
}
command.run(args2);
return;
}
}
HELP_COMMAND.run(args);
}
private static Command findCommand(String name) {
for (Command command : COMMANDS) {
if (command.name().equals(name)) {
return command;
}
}
return null;
}
//测试服务集合
private static Command[] COMMANDS = new Command[] {
HELP_COMMAND,
//RunTestCommand命名为“runt
new RunTestCommand(),
new DumpCommand(),
new EventsCommand(),
};
}
RunTestCommand.run()方法将具体的执行业务递交给UiAutomatorTestRunner类的run方法执行
package com.android.commands.uiautomator;
public class RunTestCommand extends Command {
public RunTestCommand() {
//设置name
super("runtest");
}
//被调用入口
@Override
public void run(String[] args) {
int ret = parseArgs(args);
...
if (mTestClasses.isEmpty()) {
addTestClassesFromJars();
if (mTestClasses.isEmpty()) {
System.err.println("No test classes found.");
System.exit(ARG_FAIL_NO_CLASS);
}
}
//调用UiAutomatorTestRunner类的run方法
getRunner().run(mTestClasses, mParams, mDebug, mMonkey);
}
protected UiAutomatorTestRunner getRunner() {
if (mRunner != null) {
return mRunner;
}
if (mRunnerClassName == null) {
mRunner = new UiAutomatorTestRunner();
return mRunner;
}
...
// won't reach here
return null;
}
}在UiAutomatorTestRunner的run方法中初始化执行参数，然后调用start方法中初始化UiAutomationShellWrapper并执行测试任务。UiAutomationShellWrapper的connect方法连接系统测试服务。
package com.android.uiautomator.testrunner;
/**
* @hide
*/
public class UiAutomatorTestRunner {
public void run(List<String> testClasses, Bundle params, boolean debug, boolean monkey) {
//全局异常捕获
Thread.setDefaultUncaughtExceptionHandler(new UncaughtExceptionHandler() {...});
mTestClasses = testClasses;
mParams = params;
mDebug = debug;
mMonkey = monkey;
start();
System.exit(EXIT_OK);
}
protected void start() {
...
//创建Handler线程对象
mHandlerThread = new HandlerThread(HANDLER_THREAD_NAME);
mHandlerThread.setDaemon(true);
mHandlerThread.start();
//创建UiAutomationShellWrapper对象
UiAutomationShellWrapper automationWrapper = new UiAutomationShellWrapper();
//创建测试连接，测试服务初始化完毕
automationWrapper.connect();
...
try {
...
//执行测试用例
// run tests for realz!
for (TestCase testCase : testCases) {
prepareTestCase(testCase);
testCase.run(testRunResult);
}
} catch (Throwable t) {...
} finally { ...
}
}
}
UiAutomationShellWrapper 类的connect方法初始化了UiAutomation对象，UiAutomation提供测试所需功能API。
public class UiAutomationShellWrapper {
private static final String HANDLER_THREAD_NAME = "UiAutomatorHandlerThread";
//构建HandlerThrea对象
private final HandlerThread mHandlerThread = new HandlerThread(HANDLER_THREAD_NAME);
private UiAutomation mUiAutomation;
public void connect() {
if (mHandlerThread.isAlive()) {
throw new IllegalStateException("Already connected!");
}
//调用start方法启动线程
mHandlerThread.start();
//创建UiAutomation对象
mUiAutomation = new UiAutomation(mHandlerThread.getLooper(),
new UiAutomationConnection());
//创建UiAutomation测试连接
mUiAutomation.connect();
}
//断开连接
public void disconnect() {
if (!mHandlerThread.isAlive()) {
throw new IllegalStateException("Already disconnected!");
}
mUiAutomation.disconnect();
mHandlerThread.quit();
}
public UiAutomation getUiAutomation() {
return mUiAutomation;
}
}到此uiautomator进程已经获取UiAutomation对象，可以通过UiAutomation对象获取屏幕元素信息、发送按键事件、滑动屏幕、点击屏幕等。以下代码展示部分重要API，无论是Uiautomator1.0还是Uiautomator2.0最终都是通过UiAutomation对象来执行测试动作的。

四、模拟Uiautomator实现测试服务
特点：
1、系统 已启动其他测试服务时，可以启动服务。
2、在系统内做服务时可以动态控制测试服务的注册、注销，实现多服务并存
3、API功能需自己实现，业务亲和度强。创建测试类MyUiAutomation
//在包android.app 下创建类
public class MyUiAutomation {
private final HandlerThread mHandlerThread = new HandlerThread("MyUiAutomation");
UiAutomation mUiAutomation;
Method mDisconnectMethod;
public void connect() {
mHandlerThread.start();
//如果不在android.app包下，则无法调用构造方法。
mUiAutomation = new UiAutomation();
final UiAutomationConnection uiAutomationConnection = new UiAutomationConnection();
try {
//系统已隐藏相关方法，因此使用反射方式调用
Class[] parameterTypes = new Class[]{Looper.class, Class.forName("android.app.IUiAutomationConnection")};
Object[] parameterValues = new Object[]{mHandlerThread.getLooper(), uiAutomationConnection};
mUiAutomation = UiAutomation.class.getConstructor(parameterTypes).newInstance(parameterValues);
Method connectMethod = UiAutomation.class.getMethod("connect");
mDisconnectMethod = UiAutomation.class.getMethod("disconnect");
connectMethod.setAccessible(true);
connectMethod.invoke(mUiAutomation);
AccessibilityNodeInfo windowNode = mUiAutomation.getRootInActiveWindow();
if (windowNode != null) {
System.out.println("get Widow:" + windowNode.getClassName());
}
} catch (Exception e) {
e.printStackTrace();
}
}创建Java接口类，并创建测试连接，调用测试服务方法
package com.android.demo;
import android.app.MyUiAutomation;
import android.app.UiAutomation;
/**
* Created by walker on 2019-07-31.
*
* @description
*/
public class CmdMain {
public static void main(String[] args) {
MyUiAutomation myUiAutomation = new MyUiAutomation();
myUiAutomation.connect();
UiAutomation uiAutomation= myUiAutomation.getUiAutomation();
AccessibilityNodeInfo windowNode = uiAutomation.getRootInActiveWindow();
if (windowNode != null) {
System.out.println("get Widow:" + windowNode.getClassName());
}
}
}
构造apk文件并执行
local_file=./test.apk
runClass=com.android.demo.CmdMain
app_file=/data/local/tmp/test.apk
//将执行文件推送到设备中
adb push ${local_file} ${app_file}
//通过shell命令调用程序，以CmdMain的main()方法开始执行
adb shell ANDROID_DATA=/data/local/tmp CLASSPATH=${app_file} exec app_process /system/bin ${runClass}以上是关于Uiautomator1.0与Uiautomator2.0测试项目搭建与运行原理的主要内容，如果未能解决你的问题，请参考以下文章
