I'm making a program in pyqt4, using python3.4 and host on Gitlab. When I'm trying to make a build this fails.
This is the .gitlab-ci.yml file form my project:
before_script:
- apt-get update -qy
- apt-get install -y python3 python3-dev python3-pip python3-pyqt4
- export DISPLAY=:0.0
test:
script:
- python3 main.py
The error is: main.py: cannot connect to X server: 0.0. I am trying without export DISPLAY=:0.0 and nothing
If PyQt5 is an option, Qt 5 has the "minimal" platform plugin. To use it, modify the argv passed to QApplication to include ['-platform', 'minimal'].

For PyQt4, you could use a virtual X Server:
sudo apt-get install xvfb
xvfb-run python render.py
(reference: https://stackoverflow.com/a/13215192/829568)
I've tried:
['-platform', 'minimal'] in sys.argv for QApplication : Failedxvfb-run: error: xauth command not found (even after setting the PATH)But QT_QPA_PLATFORM: "offscreen" work like a charm and saved the day.
example:
pytest:
image: python:3.6
variables:
QT_QPA_PLATFORM: "offscreen"
script:
- pytest tests/
Thanks to steve
Would like to suggest an alternative answer to azzamasa's
Using pytest with pytest-qt, add a pytest option (preferably in conftest.py) to indicate if the application should show or not:
def pytest_addoption(parser):
parser.addoption('--show-gui', action='store_true')
Use qapp_args fixture to provide the needed arguments -platform offscreen:
@pytest.fixture(scope="session")
def qapp_args(show_gui: bool):
if not show_gui:
empty_arg_stands_for_exe_path = ''
return [empty_arg_stands_for_exe_path, '-platform', 'offscreen']
return []
