錄製CodedUI找不到記錄控制

Question

所以，我已經走了，使用的代碼生成器在Visual Studio中生成編碼的UI測試。我們有一個TreeList的wpf應用程序。我將它記錄到第一個框中，輸入一個值，然後單擊第二個框，然後鍵入一個新值。沒什麼超級花式。

public void RecordedMethod1() 
{ 
    #region Variable Declarations 
    WpfCell uIItemCell = this.UIWindowWindow.UIEntityTesterControlCustom.UIEntityTesterTreeListTree.UIEntityTesterTreeListTreeItem.UIItemCell; 
    WpfEdit uIInvoice1InvoiceIDEdiEdit = this.UIWindowWindow.UIEntityTesterControlCustom.UIEntityTesterTreeListTree.UIEntityTesterTreeListTreeItem.UIItemCell.UIInvoice1InvoiceIDEdiEdit; 
    WpfCell uIItemCell1 = this.UIWindowWindow.UIEntityTesterControlCustom.UIEntityTesterTreeListTree.UIEntityTesterTreeListTreeItem.UIItemCell1; 
    WpfEdit uI_localTextBoxEdit = this.UIWindowWindow.UIEntityTesterControlCustom.UIEntityTesterTreeListTree.UIEntityTesterTreeListTreeItem.UIItemCell11.UI_localTextBoxEdit; 
    #endregion 

    // Click cell 
    Mouse.Click(uIItemCell, new Point(92, 18)); 

    // Type '1' in 'Invoice:1/InvoiceID|Editor' text box 
    uIInvoice1InvoiceIDEdiEdit.Text = this.RecordedMethod1Params.UIInvoice1InvoiceIDEdiEditText; 

    // Click cell 
    Mouse.Click(uIItemCell1, new Point(136, 9)); 

    // Type '2/1/2012' in '_localTextBox' text box 
    uI_localTextBoxEdit.Text = this.RecordedMethod1Params.UI_localTextBoxEditText; 
} 

#region Properties 
public virtual RecordedMethod1Params RecordedMethod1Params 
{ 
    get 
    { 
     if ((this.mRecordedMethod1Params == null)) 
     { 
      this.mRecordedMethod1Params = new RecordedMethod1Params(); 
     } 
     return this.mRecordedMethod1Params; 
    } 
} 

它與第一Mouse.Click（）這個錯誤崩潰叫

據我可以告訴（當我做了各種慢步驟/ null檢查）。無法找到UIEntityTesterTreeListTree的控件。它看起來不在被映射的路徑下。顯然，這個路徑並不是UIWindowWindow.UIEntityTesterControlCustom.UIEntityTesterTree的簡單例子，但是在此之前還有幾個子區域需要經歷。

我試過幾次重新映射，但沒有運氣。我寧願不用硬編碼，所以希望這裏有人能幫我找到解決這個問題的方法。

謝謝！

你必須編輯WpfCell的搜索屬性，以確保他們使用正確的價值觀。編碼UI測試生成器通常太專用，無法一直工作，我發現將這些值編輯爲最小公分母是最佳實踐。 Here's一個好地方開始。

我沒有太多的經驗，修改搜索屬性的位置，以尋找在樹中的位置，因爲我發現它使代碼更復雜，並不總是在我的經驗，非常穩定。如果某些元素在開發中被添加或移動，它將會破壞您的所有代碼，您將不得不返回並更改所有映射的參數。我的建議是讓開發人員爲元素添加標識屬性（例如唯一的名稱標籤），以便您可以在搜索中指定該屬性。

如果您熟悉C＃中，它可能會更容易，而不是你的代碼映射。如果你有一個元素的特定屬性，那當然會更容易。例如：

<wpfelement> 
    <subElement name='someElement'> 
     <button name='oneButton'>Click me.</button> 
    </subElement> 
</wpfelement> 
<wpfelement> 
    <subElement name='someOtherElement'> 
     <button name='secondButton'>Click me.</button> 
    </subElement> 
</wpfelement> 

會在地圖的發現：

public WpfButton UIItemCell 
{ 
    get 
    { 
     WfpButton target = new WpfButton(parentElement); 
     target.SearchProperties["name"] = "secondButton"; 
     return target; 
    } 
} 

這樣，無論身在何處的元素在你的樹，編碼的UI引擎輕鬆找到它。如果您想要的單元格沒有任何標識屬性，將它們添加到UI中會很有幫助，但是您還可以使用element.GetChildren()從最接近的具有標識符的父級進行導航，並從中進行過濾。
