應用.NET 3.0提供的UIAutomation，我們可以用以下步驟來進行測試：
1. 啟動應用程序
C#代碼 
- string path = @"The Path To The Application";
- Process process = Process.Start(path);
string path = @"The Path To The Application";Process process = Process.Start(path);
2. 獲得主窗口對應的AutomationElement
C#代碼
- Thread.Sleep(1000);
- AutomationElement aeMainWindow = AutomationElement.FromHandle(process.MainWindowHandle);
Thread.Sleep(1000);AutomationElement aeMainWindow = AutomationElement.FromHandle(process.MainWindowHandle);
3. 獲得按鈕對應的AutomationElement
C#代碼
- AutomationElement aeHelloButton = aeMainWindow.FindFirst(TreeScope.Children, new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.Button));
AutomationElement aeHelloButton = aeMainWindow.FindFirst(TreeScope.Children, new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.Button));
4. 點擊按鈕
此處的GetCurrentPattern相當于Query Interface，Pattern也是UIAutomation的精髓所在。給不同的UI框架做不同的adapter，實現各種各樣的pattern，也就是建立了一個概念上的大一統UI。
C#代碼
- InvokePattern ipHelloButton = (InvokePattern) aeHelloButton.GetCurrentPattern(InvokePattern.Pattern);
- ipHelloButton.Invoke();
InvokePattern ipHelloButton = (InvokePattern) aeHelloButton.GetCurrentPattern(InvokePattern.Pattern);ipHelloButton.Invoke();
5. 獲得文本框對應的AutomationElement
C#代碼
- AutomationElement aeHelloTextBox = aeMainWindow.FindFirst(TreeScope.Children, new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.Edit));
AutomationElement aeHelloTextBox = aeMainWindow.FindFirst(TreeScope.Children, new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.Edit));
6. 取得文本框中的文本
C#代碼
- TextPattern tpHelloTextBox = (TextPattern) aeHelloTextBox.GetCurrentPattern(TextPattern.Pattern);
- string text = tpHelloTextBox.DocumentRange.GetText(-1);
TextPattern tpHelloTextBox = (TextPattern) aeHelloTextBox.GetCurrentPattern(TextPattern.Pattern);string text = tpHelloTextBox.DocumentRange.GetText(-1);
7. 監聽窗口被關閉事件
C#代碼
- Automation.AddAutomationEventHandler(WindowPattern.WindowClosedEvent, aeMainWindow, TreeScope.Element, HandleMainWindowClose);
- private static void HandleMainWindowClose(object sender, AutomationEventArgs e)
- {
- Console.WriteLine("Main Window Closed");
- }
Automation.AddAutomationEventHandler(WindowPattern.WindowClosedEvent, aeMainWindow, TreeScope.Element, HandleMainWindowClose);private static void HandleMainWindowClose(object sender, AutomationEventArgs e){ Console.WriteLine("Main Window Closed");}8. 關閉窗口
C#代碼
- process.Kill();
process.Kill();
此時控制臺上就會打印出"Main Window Closed"
整個過程演示了三個主要功能：
1、如何主動去操縱界面（點擊按鈕）
2、如何取得界面的狀態（獲得文本）
3、如何監聽界面的事件（關閉窗口事件）
結論：
UIAutomation可以給Win32, WindowsForms， WPF編寫的應用程序撰寫驗收測試。
