UI Automator 测试工具定义以及用途
UI Automator 测试框架提供了一组 API，用于构建在用户应用和系统应用上执行交互的界面测试。通过 UI Automator API，您可以执行在测试设备中打开“设置”菜单或应用启动器等操作。UI Automator 测试框架非常适合编写黑盒式自动化测试，此类测试的测试代码不依赖于目标应用的内部实现细节。
优点：可以对所有的操作来进行自动化，操作简单（eg:点击事件 ，侧滑事件，上拉事件，以及模拟键盘输入测试用例）。可以测试所有设备的程序。
缺点：必须要Android4.0以上才能使用。
UI Automator 的执行呢，需要我们编写完毕打成jar包，直接上传到/data/local/tmp/ 目录下面，然后用adb 命令执行即可。由于是安卓原生的，比较稳定，运行的速度也比较快。
我们下载了安卓的环境变量后，然后下载任意大于4.0的安卓版本sdk即可。
都会有这个jar包，我们在写代码，创建工程的时候，直接引入即可。
如何获取定位呢，我们可以uiautomatorviewer。
UI Automator 测试框架的主要功能包括：
用于检查布局层次结构的查看器。
用于检索状态信息并在目标设备上执行操作的 API。
支持跨应用界面测试的 API。
UI Automator 测试框架提供了一个 UiDevice 类，用于在运行目标应用的设备上访问和执行操作。您可以调用其方法以访问设备属性，如当前屏幕方向或显示屏尺寸。UiDevice 类还可用于执行以下操作：
改变设备的旋转。
按硬件键，如“音量调高按钮”。
按返回、主屏幕或菜单按钮。
打开通知栏。
截取当前窗口的屏幕截图。
UI Automator API
通过 UI Automator API，您可以编写可靠的测试，而无需了解目标应用的实现细节。您可以使用这些 API 在多个应用间捕获和操纵界面组件：
UiCollection：枚举容器的界面元素，目的是为了计数，或者按可见文本或内容说明属性来定位子元素。
UiObject：表示设备上可见的界面元素。
UiScrollable：支持搜索可滚动界面容器中的项目。
UiSelector：表示对设备上的一个或多个目标界面元素的查询。
Configurator：可让您设置用于运行 UI Automator 测试的关键参数。

官方文档有着详细的介绍
正常的我们加入后，在后可以看到，有什么类，方式是什么，里面有什么api。
我们可以在引入后查看。

下面给大家展示一个UiAutomator的testcase
package cn.cool;
import com.android.uiautomator.testrunner.UiAutomatorTestCase;
import android.os.RemoteException;
public class Testone extends UiAutomatorTestCase {
@Override
protected void setUp() throws Exception {
super.setUp();
}
public void testCool() throws RemoteException, InterruptedException {
}
@Override
protected void tearDown() throws Exception {
}
}
然后我们可以在实际的项目中，去实现我们真实的业务的代码。实现完毕呢，
我们就可以用 adb . shell push cool.jar /data/local/tmp/
然后使用
adb shell uiautomator runtest cool.jar -c cn.cool.Testone
就可以执行了。uiautomator 由于只能打成jar包，所以它不能直接在编辑器上进行调试。
