TestStack White在WPF应用程序中找不到TextBox [英] TestStack White doesn't find TextBox in WPF Application
本文介绍了TestStack White在WPF应用程序中找不到TextBox的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我使用TestStack White框架自动测试WPF应用程序 它需要打开模式窗口并访问其中的TextBox.一切正常，但是怀特找不到文本框，尽管它找到了窗口的其他元素
I use TestStack White framework to automate testing of a WPF Application It needs to open modal window and access TextBox in it. Everything works well, but White can't find Textbox, although it finds other elements of window
我尝试了以下代码行:
TestStack.White.UIItems.TextBox TextBox = CreateBranch.Get<TestStack.White.UIItems.TextBox>(SearchCriteria.byAutomationId("Title"));
其中CreateBranch是模式窗口
where CreateBranch is modal window
我还尝试了(SearchCriteria.All)，(SearchCriteria.ByControlType)，但没有任何效果
I also tried (SearchCriteria.All), (SearchCriteria.ByControlType) and nothing works
编码的UI工具通过AutomationID可以很好地找到此元素，但是我需要以白色完成
Coded UI tool finds this element well by AutomationID, but I need to do it in White
UISpy和其他类似工具可以识别此控件并查看其AutomationID
UISpy and other similar tools recognize this control and see its AutomationID
此文本框是自定义控件，这是它的代码，出于隐私考虑，我更改了名称空间名称:
This textbox is custom control, here's code for it, I changed namespace name for privacy:

推荐答案
让我知道是否可行
TextBox = (TextBox)CreateBranch
.Get(SearchCriteria.ByAutomationId("Title").AndOfFramework(WindowsFramework.Wpf));
在添加新来源后进行了编辑
Edited after new source added
您必须创建特定的 AutomationPeer 用于您的自定义控件，并通过方法OnCreateAutomationPeer()的覆盖将其返回.
You have to create a specific AutomationPeer for your custom control and return it via the override of the method OnCreateAutomationPeer().
您的控件是TextBox控件的子类，因此您只需返回一个新的TextBoxAutomationPeer实例，或从中创建自定义AutomationPeer.
Your control is a subclass of the TextBox control so you can just return a new TextBoxAutomationPeer instance or create your custom AutomationPeer from it.
public class XTextBox : TextBox
{
...
protected override AutomationPeer OnCreateAutomationPeer()
{
return new XTextBoxAutomationPeer(this);
// or just use the TextBoxAutomationPeer
// return new TextBoxAutomationPeer(this);
}
...
}
自定义自动化对等体
public class XTextBoxAutomationPeer : TextBoxAutomationPeer
{
public XTextBoxAutomationPeer(XTextBox owner)
: base(owner)
{
}
protected override string GetClassNameCore()
{
return "XTextBox";
}
}
