在xaml子元素中添加AutomationId

Question

我目前正在从事自动化UI测试支持，不幸的是，这是第一次。我在无法添加AutomationId以使其出现在生成的xml文件的所需元素中的问题上感到困惑。

问题是该元素是另一个元素的子元素，当我添加AutomationId时（无论是在C＃代码中还是在XAML中），该AutomationId仅出现在最顶部的xml元素中，该元素是一些矩形面板（按钮），但是在此按钮中还有一些其他元素如图片，按钮标签，带有计数器的标签。也许将来测试人员也需要访问这些子元素，但现在我只能通过ID找到最上方的矩形区域。

这里是元素SomeEntryView及其父元素View的代码结构，该代码结构在创建布局并将元素添加到此布局时用于代码中。

public partial class SomeEntryView : MainMenuButton
{ ...

public partial class MainMenuButton : ContentView, IDisposable
...

public class ContentView : TemplatedView
...

public class TemplatedView : Layout
...

public abstract class Layout : View

xaml中的元素是通过这种方式定义的

<c:MainMenuButton
x:Class="...Views.SomeEntryView"
AutomationId="automationIdTest"
... />

结果xml文件如下所示

<Custom AcceleratorKey="" AccessKey="" AutomationId="automationIdTest" ClassName="" FrameworkId="XAML" HasKeyboardFocus="False" HelpText="" IsContentElement="True" IsControlElement="True" IsEnabled="True" IsKeyboardFocusable="False" IsOffscreen="False" IsPassword="False" IsRequiredForForm="False" ItemStatus="" ItemType="" LocalizedControlType="custom" Name="" Orientation="None" ProcessId="8804" RuntimeId="42.267070.4.13" x="27" y="151" width="1868" height="148">

        </Custom>

如您所见，最顶层的元素上有AutomationId="automationIdTest"，但是是否有办法以某种方式将AutomationId添加到其子元素中？在将此MainMenuButton作为View添加到布局中时，我还尝试通过C＃代码添加AutomationId。
