Test capabilities for FastAPI apps ran with ui.run_with

[mbrulatout]

Hello,

For ui.run apps, the screen class provides the appropriate features to test your current app (see here ).

I'm running NiceGUI through ui.run_with and as it stands I'm unable to run any UI test.

There seems to be a bit of rework in screen.py class at the very least as it calls ui.run

Yes, @mbrulatout, so far we used the Screen class only for testing apps based on ui.run, not ui.run_with. Adding support for the latter would be great. But we could certainly need some help. Anyone interested in giving it a go? 🙂
