XUnit/NUnit headless templates

[maxkatz6]

Is your feature request related to a problem? Please describe.

It would greatly improve the adoption of Headless testing if we ship testing templates as well

Describe the solution you'd like

Two templates based on Nunit and Xunit with:

• Avalonia app initialization
• Simple test with button click assert
• Link to the documentation for more info

Possibly a third template with a whole solution together (xplat?) and sharing application between them?

Describe alternatives you've considered

No response

Additional context

Headless platform documentation https://docs.avaloniaui.net/docs/next/concepts/headless/

@maxkatz6 Do you know of any implementations of the headless platform that you could link here? Would really appreciate it :)

Avalonia.Controls.TreeDataGrid uses headless tests:

Are there any plans to include this in an upcomming release? I'm going through the process of writing some tests for my app now and am really wishing I had a templated project or a delibirate/ containerized example of the setup for these headless tests to go off of. Refrences to UnitTest in source are usefull, but for me as a bit of a novice they can be a bad place to start learning. Maybe this just a criticism of myself idk, either way this is definetly something I'd find useful personaly.

@10Peppermill we have some generic samples as well: https://github.com/AvaloniaUI/Avalonia.Samples/tree/main/src/Avalonia.Samples/Testing/TestableApp.Headless.XUnit. If it might help.
