如何从UITestControl获取ItemStatus？ [英] How do I get ItemStatus from a UITestControl?

问题描述

UI自动化框架具有基类 AutomationElement ，它具有属性 ItemStatus ，可用于存储任意字符串。我正在尝试从Visual Studio 2010中获取该属性，编码的UI测试基类， UITestControl 。

The UI Automation framework has a base class, AutomationElement, that has a property, ItemStatus, that can be used to store arbitrary strings. I'm trying to get that property from the Visual Studio 2010 Coded UI Tests base class, UITestControl.

推荐答案

查看编码的UI测试为<$ c生成的代码$ c> WpfControl 。它具有属性NativeElement。此属性是 AutomationElement 。

Look at the Coded UI Tests generated code for WpfControl. It has a property, NativeElement. This property is an AutomationElement.

public abstract class WpfControl : UITestControl
{
    ...

    public virtual object NativeElement
    {
        get
        {
            return ((object)(this.GetProperty(UITestControlProperties.Common.NativeElement)));
        }
    }

    ...
}

您可以编写扩展方法来强制转换并获取ItemStatus。

You can write an extension method to cast it and get ItemStatus.

public static string GetItemStatus(this WpfControl control)
{
    var automationElement = (AutomationElement)control.NativeElement;
    return automationElement.Current.ItemStatus;
}

我不确定为什么NativeElement被记录为对象（这会使getter变得多余）。所有WPF控件的NativeElement的类型为 AutomationElement 。我建议编辑生成的代码，然后直接调用 control.NativeElement.Current.ItemStatus 。

I am not certain why NativeElement is recorded as an object (which makes the getter cast redundant). All WPF controls' NativeElement are of type AutomationElement. I would suggest editing the generated code and simply calling control.NativeElement.Current.ItemStatus directly.
