所謂“猴子測試”，就是自動化UI測試龟再，模擬在屏幕上隨便亂點尼变，來達(dá)到自動化測試的目的嫌术，節(jié)省了人力。

測試非常簡單割按，本文用到了Github上的 UI AutoMonkey 來集成的适荣，地址：https://github.com/jonathanpenn/ui-auto-monkey

步驟如下：

1.選擇Instrument中的Automation院领，清空里面的js代碼。
2.把 UI AutoMonkey 中的 UIAutoMonkey.js 文件里面的400多行js代碼拷貝汪诉，粘貼到Automation里面扒寄。（或者直接拷貝下面的js代碼）
3.點擊左上角的紅色按鈕運行拟烫，模擬器就開始工作了硕淑，可以看到屏幕自動出現(xiàn)快速亂點的效果嘉赎。

測試效果展示：

備注：
測試包括了：點擊公条、滾動迂曲、清掃路捧、捏合、橫豎屏等队寇。

附j(luò)s測試代碼：

        * 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
