app.storage.user in unit tests throws error.

Description

When i try to acces app.storage.user in my testcode It throws an error. Even though I added the storage secret inside UI.run and my testscode by using screen.ui_run_kwargs['storage_secret'] = "123".

raise RuntimeError('app.storage.user needs a storage_secret passed in ui.run()')

gui.py

@ui.page("/")
@ui.page("/training")
def training_page():
    Training()

if __name__ in {"__main__", "__mp_main__"}:
    ui.run(port=7000, storage_secret="123")

TrainingTests.py

from nicegui import app, ui
from nicegui.testing import Screen

def test_withscreen(screen: Screen):
    from GUI.gui import training_page
    screen.ui_run_kwargs['storage_secret'] = "123"
    screen.open("/training")

    app.storage.user['count'] = app.storage.user.get('count', 0) + 1

Hi @JanHaegdorensPXL,

I guess you're trying to access the user storage from within the pytest thread, which doesn't work.
We usually test for UI element that depend on stored values. Alternatively you can read the storage files like we do in test_storage.py:
