录制CodedUI找不到记录控制

Question

所以，我已经走了，使用的代码生成器在Visual Studio中生成编码的UI测试。我们有一个TreeList的wpf应用程序。我将它记录到第一个框中，输入一个值，然后单击第二个框，然后键入一个新值。没什么超级花式。

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; 
    } 
} 

它与第一Mouse.Click（）这个错误崩溃叫

据我可以告诉（当我做了各种慢步骤/ null检查）。无法找到UIEntityTesterTreeListTree的控件。它看起来不在被映射的路径下。显然，这个路径并不是UIWindowWindow.UIEntityTesterControlCustom.UIEntityTesterTree的简单例子，但是在此之前还有几个子区域需要经历。

我试过几次重新映射，但没有运气。我宁愿不用硬编码，所以希望这里有人能帮我找到解决这个问题的方法。

谢谢！

你必须编辑WpfCell的搜索属性，以确保他们使用正确的价值观。编码UI测试生成器通常太专用，无法一直工作，我发现将这些值编辑为最小公分母是最佳实践。 Here's一个好地方开始。

我没有太多的经验，修改搜索属性的位置，以寻找在树中的位置，因为我发现它使代码更复杂，并不总是在我的经验，非常稳定。如果某些元素在开发中被添加或移动，它将会破坏您的所有代码，您将不得不返回并更改所有映射的参数。我的建议是让开发人员为元素添加标识属性（例如唯一的名称标签），以便您可以在搜索中指定该属性。

如果您熟悉C＃中，它可能会更容易，而不是你的代码映射。如果你有一个元素的特定属性，那当然会更容易。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> 

会在地图的发现：

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

这样，无论身在何处的元素在你的树，编码的UI引擎轻松找到它。如果您想要的单元格没有任何标识属性，将它们添加到UI中会很有帮助，但是您还可以使用element.GetChildren()从最接近的具有标识符的父级进行导航，并从中进行过滤。
