I am currently writing tests for my .net framework 4.8 wpf application. I have a few events of the style

    public event CustomEventHandler ValueChanged;
    public delegate void CustomEventHandler(double newValue);

XUnit has a function to test Events. But is requires a standard eventhandler with custom EventArgs derived from EventArgs (Assert.Raises()).

How do I test the above event with XUnit if I cannot use EventArgs?

Create a wrapper function – John Dec 03 '20 at 07:03
Wouldn't this only make the wrapper function testable and not the event itself? – b.holz Dec 03 '20 at 07:37
