所谓“猴子测试”，就是自动化UI测试，模拟在屏幕上随便乱点，来达到自动化测试的目的，节省了人力。
测试非常简单，本文用到了Github上的 UI AutoMonkey 来集成的，地址：https://github.com/jonathanpenn/ui-auto-monkey
步骤如下：
1.选择Instrument中的Automation，清空里面的js代码。
2.把 UI AutoMonkey 中的 UIAutoMonkey.js 文件里面的400多行js代码拷贝，粘贴到Automation里面。（或者直接拷贝下面的js代码）
3.点击左上角的红色按钮运行，模拟器就开始工作了，可以看到屏幕自动出现快速乱点的效果。
测试效果展示：

备注：
测试包括了：点击、滚动、清扫、捏合、横竖屏等。
附js测试代码：

function UIAutoMonkey() {
this.config = {
//run either by minutesToRun or numberOfEvents. Only one of these can set. (To use minutes you can use config.numberOfEvents = 0)
//minutesToRun = 60 * 8; //sample to run for 8 hours.
//checkTimeEvery = 60; //how often to check (in events) if minutesToRun has is used.
numberOfEvents: 1000,
delayBetweenEvents: 0.05, // In seconds
/**
* Sometimes the monkey can fall into UI Holes from which it it is hard to escape. The monkey may then spend an inordinate
* amount of time in such holes, neglecting other parts of the application.
*
* For example, if a parent Window P has a large image
* and clicking on the image opens a child window C from which one exits by tapping a small X on the top right, then until that small X is
* tapped we will remain in C. conditionHandlers offer the developer the option to periodically recognize that we are in C and press the X.
*
* See buttonHandler.js for a specialized conditionHandler useful when a top level button can be used to escape from a UI hole.
*
* conditionHandlers are objects that respond to the following methods:
* isTrue(target, eventNumber): returns True if the condition is true given target and event number eventNumber.
* checkEvery(): How many events should pass before we check.
* handle(target, mainWindow) handle the condition.
* isExclusive() if true then if this condition's handler is invoked then processing subsequent conditions is skipped for this particular event. This
* is usually set to true as it allows the condition to exit a UI hole and at that point there may be no point executing other conditions
* logStats() log statics using UIALogger;
* condition handlers must have the following property
* statsHandleInvokedCount - the count of the number of times we were invoked
*/

/**
* Unfortunately if the application is not responsive "ANR", the monkey may not notice and continue to fire events not realizing that
* the application is stuck. When run via continuous integration users may not notice that "successful" monkey runs in fact were in an
* ANR state.
*
* To deal with this the monkey supports ANR detection. Using an anrFingerprint function it periodically takes a fingerprint and if these
* are identical for a specified interval then an ANR exception is thrown.
