1. InstrumentationRegistry类

1.1. 类说明：

一个暴露的注册实例，持有instrumentation运行的进程和参数，还提供了一种简便的方法调用instrumentation, application context和instrumentation参数。

1.2 相关API

返回类型	API
static Bundle	getArguments(): 返回一个instrumentation参数副本
static Context	getContext():  返回instrumentation对应包的Context
static Instrumentation	getInstrumentation(): 返回当前运行的instrumentation
static Context	getTargetContext(): 返回一个目标应用程序的Context
static void	registerInstance(Instrumentation instrumentation, Bundle arguments): 记录或暴露当前instrumentation运行和instrumentation参数包的副本，存储在注册中心

1.3 简单示例

 1.3.1 测试代码

 1.3.2 运行结果

2. UiDevice新增API

2.1 API 介绍

返回类型	API
void	dumpWindowHierarchy(OutPutStream out): 获取当前页面层级到输出流
String	executeShellCommand(String cmd): 执行一个shell命令。备注：此方法只支持api21以上，手机需要5.0系统以上
UiObject2	findObject(BySelector selector): 返回第一个匹配条件的对象
UiObject	findObject(UiSelector selector): 返回一个匹配条件的代表视图的UiObject对象
List<UiObject2>	findObjects(BySelector selector): 返回所有匹配条件的对象
<R> R	wait(SearchCondition<R> condition, long timeout): 等待的条件得到满足
