# Something seems to be broken in Beremiz application,

    49

# because after tests in test_application.py during Xvfb shutdown

# pytest returns error message:

# pytest: Fatal IO error 11 (Die Ressource ist zur Zeit nicht verfügbar) on X server :2821.

    53

# As a result of that pytest returns code 1 as some tests were failed,

    54

# but they aren't.

# To avoid this Xvfb is launched and killed not by pytest.
