Parallel tests on xUnit

[SergeyBQA]

Hello.
Can you tell me how to run parallel tests on Headless\XUnit?
Is it possible to run not only test collections in parallel, but also the tests themselves in parallel?
How can I create a new application context when running in parallel?

Versions:
Avalonia 11.0.11
Avalonia.Desktop 11.0.11
Avalonia.Headless 11.0.11
Avalonia.Headless.XUnit 11.0.11
xunit 2.9.3
xunit.runner.visualstudio 2.8.2

No. Parallel execution of UI tests is not possible.
Avalonia relies on global registrations/state, which gets recreated on each executed test. Having them in parallel could potentially break it.
