运行环境：

1，环境iMac OS X 10.9.5

2，工具Xcode Version 6.1 (6A1052c)

3，签约证书（开发者提供）

4，iphone设备（系统IOS6、IOS7、IOS8.1）

UI AUtoMonkey是一款非常简单的IOS压力测试工具。通过它，你可以向ios设备发送滑动、拖动、旋转、甚至锁屏和解锁指令。原文github地址：https://github.com/jonathanpenn/ui-auto-monkey

首先，使用xcode打开你的ios项目，从“Product”菜单中选择“Profile”（或者直接快捷键Command+i),这样就可以构建ios项目，并启动工具模板选择器。

下一步，在选择器中选择“UI Automation”。当我们创建了自动化模板后，就可以测试app的性能了。

在Scripts面板中，点击“Editor Log”，在下拉列表中选择“Script”，点击“Add”按钮，在下拉列表中选择”Create”,就可以新建一个js脚本。

将UIAutoMonkey.js这个文件的内容粘贴到新建的js脚本中（或者可以直接将UIAutoMonkey.jsimport进去。

此时，我们可以直接点击播放按钮，来执行这段脚本，monkey测试就开始了。

// If the following line is uncommented, then screenshots are taken

// every "n" seconds.

//screenshotInterval: 5,



// Events are triggered based on the relative weights here. The event

// with this highest number gets triggered the most.

//

// If you want to add your own "events", check out the event method

// definitions below.

eventWeights: { //每个事件的触发几率,如果tab事件的值为100、orientation事件的值为1，那么tab事件触发的几率就是orientation的100倍。

// Event Methods

// Any event probability in the hash above corresponds to a related event

// method below. So, a "tap" probability will trigger a "tap" method.

//

// If you want to add your own events, just add a probability to the hash

// above and then add a corresponding method below. Boom!

// Each event method can call any other method on this UIAutoMonkey object.

// All the methods at the end are helpers at your disposal and feel free to

// add your own.

Note: The Automation instrument works only with apps that have been code signed with a development provisioning profile when they are built in Xcode. Apps signed with a distribution provisioning profile cannot be controlled with the UI Automation programming interface. However, because scripts run outside your app, the app version you are testing can be the same one you submit to the App Store, as long as you rebuild it with the distribution profile.

Important: Simulated actions may not prevent your test device from auto-locking. To ensure that auto-locking does not happen, before running tests on a device, you should set the Auto-Lock setting to Never.

iOS 8 Enhancement: iOS 8 includes a new Enable UI Automation preference under Settings > Developer, which allows third-party developers finer control of when their devices are available to perform automation. For physical iOS devices, this setting is off by default and must be enabled prior to performing any UI Automation. In the simulator, the setting is enabled by default.
