所以我已经离开并使用Visual Studio中的代码生成器生成编码的UI测试。我们有一个带有TreeList的wpf应用程序。我将它记录到第一个框，输入一个值，然后单击第二个框，然后键入一个新值。没什么特别的。
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;
}
}
在第一次Mouse.Click（）调用
时，它会因此错误而崩溃Microsoft.VisualStudio.TestTools.UITest.Extension.UITestControlNotFoundException was unhandled by user code

InnerException:
据我所知（当我做各种慢步/空检查时）。无法找到UIEntityTesterTreeListTree的控件。它看起来并不位于映射的路径下。显然，这个路径不是UIWindowWindow.UIEntityTesterControlCustom.UIEntityTesterTree的简单情况，而是在此之前还需要经过几个子区域。
我曾尝试将其重新映射几次，但没有运气。我宁愿不用硬编码，所以希望有人能帮助我找到解决问题的方法/方法。
谢谢！
答案 0 :(得分：1)
您必须编辑WpfCell的搜索属性，以确保它们使用正确的值。编码的UI测试生成器通常太具体而无法一直工作，我发现将值编辑到最小公分母是最佳实践。 Here's 一个好的开始。
我没有多少经验来修改搜索属性以按位置查找树中的位置，因为我发现它使代码更复杂并且不总是，根据我的经验，非常稳定。如果某些元素在开发中被添加或移动，它将破坏您的所有代码，并且您必须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一个标识属性（例如，唯一的名称标记），以便您可以在搜索中指定它。
如果您对c＃感到满意，则可能更容易对代码进行编码。如果你有元素的特定属性，那么当然会更容易。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>
将在您的地图中找到：
public WpfButton UIItemCell
{
get
{
WfpButton target = new WpfButton(parentElement);
target.SearchProperties["name"] = "secondButton";
return target;
}
}
这样，无论元素在树中的哪个位置，Coded UI引擎都能轻松找到它。如果您没有所需的单元格的任何标识属性，将它们添加到UI会很有帮助，但您也可以使用element.GetChildren()从具有标识符的最近父级导航并从那里过滤
