UnitTesting(Xunit)-ListBox

[Kishorekumar]

Hi All,

I Used telerik:ListBox Control which has selection changed Event and for this event I was writing Unit Test code(X-Unit).

VM Code:

var selectionChangedEventArg = parameter as System.Windows.Controls.SelectionChangedEventArgs; 
                if (selectionChangedEventArg != null && selectionChangedEventArg.OriginalSource != null)
                {}

TEST CODE:

////Arrange

 System.Windows.Controls.SelectionChangedEventArgs obj =
            new System.Windows.Controls.SelectionChangedEventArgs(routedEvent, removedItems, addedItems);

////Act

detailViewModel.SelectionChangedCommand.Execute(obj);      

 

selectionChangedEventArg.OriginalSource was null when the method is called from Test method. Any idea to make the original Source has value.
