"DeprecationWarning: desired_capabilities has been deprecated, please pass in a Service object" when running tests

[fohrloop]

I'm getting a DeprecationWarning when running tests for a dash app. A complete minimal working example would be

minimal test app

# usage_tmp.py

import dash
from dash import html

app = dash.Dash(__name__)
app.layout = html.Div([html.H1("test")])

if __name__ == "__main__":
    app.run_server(debug=True)

minimal test script

# tests\test_usage_tmp.py

from dash.testing.application_runners import import_app

# Run with pytest -k testing123
def test_testing123(dash_duo):
    app = import_app("usage_tmp")
