一、 Introduction

UI Automation 是 Microsoft .NET 3.0 框架下提供的一种用于自动化测试的技术，是在 MSAA 基础上建立

的，MSAA 就是 Microsoft Active Accessibility。UI Automation 在某些方面超过了 MSAA，UI 自动化提供了

Windows Vista 中，微软 Windows XP 的全部功能，和 Windows Server 2003。

在 UI Automation 中，所有的窗体、控件都表现为一个 AutomationElement， AutomationElement$中

包含此控件或窗体的属性，在实现自动化的过程中，我们通过其相关属性进行对控件自动化操作。对于 UI 用户界

面来说，所有显示在桌面上的 UI，其实际是一个 UI Tree，根节点是 desktop。我们可以使用 UI Spy 或者是

SPY++来获得 Window 和 Control 的相关信息。在 UI Automation 里，根节点表示为

AutomationElemnet.RootElement.通过根节点，我们可以通过窗体或控件的 Process Id、Process Name 或

者 Window Name 找到相应的子 AutomationElement，例如 Dialog、Button、 TextBox、Checkbox 等标

准控件，通过控件所对应的 Pattern 进行相关的操作。

UI Automation structure

如下图所示：

1．在服务端由 UIAutomationProvider.dll 和 UIAutomationTypes.dll 提供。

$$$$ 2．在客户端由 UIAutomationClient.dll 和 UIAutomationTypes.dll 提供。

$$$$ 3． UIAutomationCore.dll 为 UI 自动化的核心部分，负责 Server 端和 Client 端的交互。

$$$$ 4． UIAUtomationClientSideProvides.dll 为客户端程序提供自动化支持。
