自定義控件上的AutomationProperties.AutomationId未曝光

Question

我一直對我的頭反對這個問題3天，一直未能找到答案。

我有一個用WPF（dot Net 4.5）編寫的應用程序，我正在用Teststack.White試圖編寫一些自動GUI測試用例。開發人員給了一些控件的x：Names，他們通過Inspect/WPF Inspector/Visual UI Automation顯示驗證AutomationId就好了。

還有其他一些控件被埋沒得更深一些，我負責給自動化id（主要是作爲一個練習，以便我可以更熟悉後端）。這是我一直在抨擊事物的地方。

我試着給控件的AutomationProperties.AutomationId（和.Name）屬性。我給了AutomationProperties一個名稱空間定義。以及我確信SWA.Peers被引用。

我還沒有嘗試在XAML中使用屬性設置器，因爲它們目前沒有多大意義，我希望不需要在C＃中編寫東西來設置它們（如果我這樣做，我會執行它但只是希望）。

我的一位同事坐下來，我們拿出了沒有公開自動化ID屬性的最低設置（不幸的是，他和其他開發人員正在爲此未發生空白）。它看起來像：

MainWindow.xaml：

我道歉，如果這是一個簡單問題（或者如果我沒有問正確的問題）。我是一個入門級程序員，他對WPF/XAML只有粗略的瞭解。

在此先感謝您的幫助！ （希望這是任何簡單的解決方法！）

更新：做一些進一步的挖掘上UI自動化供應商之後，它看起來像所有的自定義控件必須寫入支持AutomationProperties。當然，與開發者交談，這不是案件。

當我找到解決方案時，我會發布更多信息。

沒有你的控制AutomationPeer。所以你的AutomationId設置沒有設置任何東西。

覆蓋OnCreateAutomationPeer在你的控制代碼隱藏這樣的：

protected override AutomationPeer OnCreateAutomationPeer() 
    { 
     return new IconLabelButtonAutomationPeer(this); 
    } 

您的新IconLabelButtonAutomationPeer看起來是這樣的：

public class IconLabelButtonAutomationPeer : FrameworkElementAutomationPeer 
{ 
    public IconLabelButtonAutomationPeer(IconLabelButton owner) 
     : base(owner) 
    { 
    } 
}
