使用UI Automation实现自动化测试 -4.1

Chapter 4 UI Automation Pattern

DockPattern

DockPattern用于操作可停靠容器控件，我们最熟悉的VS2005/2008中的ToolBox，Solution Explorer都可以设置不同的DockPosition， 但是目前并不支持DockPattern，所以无法做为实例来讲。使用DockPattern的前提为控件支持DockPattern。 DockPattern中的DockPosition有六个枚举变量，即Bottom、Left、Right、Top、Fill和None。如果控件支持DockPattern， 则可以获取相对应的DockPosition以及设置控件的DockPosition。
如下代码是获取控件的DockPattern、获取控件当前的DockPosition以及设置控件的DockPosition。
DockPattern的实例，所以比较遗憾。

#region DockPattern helper

/// <summary>
/// Get DockPattern
/// </summary>
/// <param name="element">AutomationElement instance</param>
/// <returns>DockPattern instance</returns>
public static DockPattern GetDockPattern(AutomationElement element)
{
object currentPattern;
if (!element.TryGetCurrentPattern(DockPattern.Pattern, out currentPattern))
{
throw new Exception(string.Format("Element with AutomationId '{0}' and Name '{1}' does not support the DockPattern.",
element.Current.AutomationId, element.Current.Name));
}
return currentPattern as DockPattern;
}

/// <summary>
/// Get DockPosition

/// <param name="element">AutomationElement instance</param>

public static DockPosition GetDockPosition(AutomationElement element)

return GetDockPattern(element).Current.DockPosition;
}

/// <summary>
/// Set DockPosition
/// </summary>
/// <param name="element">AutomationElement instance</param>
public static void SetDockPattern(AutomationElement element, DockPosition dockPosition)
{
GetDockPattern(element).SetDockPosition(dockPosition);
