the only test is (no import in file):

def test_un(qtbot):
    assert True

conftest file empty.

Not sure if it could be related to #202 or #206

thanks for help

That stacktrace just means that Qt aborted when creating a QApplication. There's nothing pytest-qt can do about that, it's something which would as well happen if you did run something like:

import sys

from PySide2.QtWidgets import QApplication
app = QApplication(sys.argv)

via Python. Do you have libxkbcommon-x11-0 installed in your environment?

Closing this for now as I don't think there's anything pytest-qt can do here - but feel free to follow up if needed!

libxkbcommon-x11-0 was the thing. thanks.
maybe could I add it to troubleshooting of doc ?

[nicoddemus]

@jgirardet good news then.

maybe could I add it to troubleshooting of doc ?

Sure, that would be appreciated, thanks. 👍
