iOS 猴子测试

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：

        //minutesToRun = 60 * 8; //sample to run for 8 hours.
        //checkTimeEvery = 60; //how often to check (in events) if minutesToRun has is used.

        * 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

        * ANR state.
        *
        * To deal with this the monkey supports ANR detection. Using an anrFingerprint function it periodically takes a fingerprint and if these
