Coded UI discovering controls

I have a ui coded ui test in visual studio 2010. I want to write a code which will:

  1. Discover all the controls on a window and child windows which are button, grid, label
  2. write a uimap with the id which is the name of the control in the code.

For starting it, I've write the following:

public void CodedUITestMethod1()
{    
   string uiTestFileName = @"D:\dev11\ConsoleApplication1\TestProject1\UIMap.uitest";

   UITest uiTest = UITest.Create(uiTestFileName);

   Microsoft.VisualStudio.TestTools.UITest.Common.UIMap.UIMap newMap = new Microsoft.VisualStudio.TestTools.UITest.Common.UIMap.UIMap(); 
   newMap.Id = "UIMap"; 
   uiTest.Maps.Add(newMap);

   GetAllChildren(BrowserWindow.Launch(new Uri("http://bing.com")), uiTest.Maps[0];);
   uiTest.Save(uiTestFileName);    
}

private void GetAllChildren(UITestControl uiTestControl, Microsoft.VisualStudio.TestTools.UITest.Common.UIMap.UIMap map)
{
   foreach (UITestControl child in uiTestControl.GetChildren())
   {
       map.AddUIObject((IUITechnologyElement)child.GetProperty(UITestControl.PropertyNames.UITechnologyElement));

       GetAllChildren(child, map);    
    }    
}

But it insert into the recursive loop and doesn't end it.

Can anyone help me?

Have you added any debugging or instrumentation to determine what control you are looking at in each iteration of the foreach loop? Just from looking at it I wouldn't expect it to enter into a infinite recursion. – Jeff Machamer

I think that to avoid possible infinite recursion you have to add this code:

private void GetAllChildren(UITestControl uiTestControl, Microsoft.VisualStudio.TestTools.UITest.Common.UIMap.UIMap map)
{
  foreach (UITestControl child in uiTestControl.GetChildren())
  {
      IUITechnologyElement tElem=(IUITechnologyElement)child.GetProperty(UITestControl.PropertyNames.UITechnologyElement);
      if (!map.Contains(tElem))
      {
          map.AddUIObject(tElem);
          GetAllChildren(child, map);    
      }
  }    
}

This way you avoid to consider the same object multiple times and keep away from possible visual tree cycle.

Before you call map.AddUIObject and GetAllChildren in the foreach loop, check to make sure the object doesn't already exist in the map collection.

Check that the child has children before calling GetAllChildren(child, map)

if(child.HasChildren) {
   GetAllChildren(child, map);
}
