Hi all,
I'm trying to build some CI tests on GitHub (with pytest) using the
official qgis/qgis Docker image. Everything works fine except for the
parts of my plugin that use Processing algorithms. I'd like to run full
workflow tests, but the processing plugin doesn't seem to be available
in the container.
When I try to load it with qgis.utils.loadPlugin('processing') I get
this error:
Python error(2): Traceback (most recent call last):
File "/usr/share/qgis/python/qgis/utils.py", line 447, in loadPlugin
__import__(packageName)
File "/usr/share/qgis/python/qgis/utils.py", line 1100, in _import
mod = _builtin_import(name, globals, locals, fromlist, level)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
ModuleNotFoundError: No module named 'processing'
Couldn't load plugin 'processing'(1): Couldn't load plugin 'processing'
I can't find much documentation on how to build CI tests for a QGIS
plugin, so I've been trying to make it work, but I don't know if I'm
doing it rightly...
I've tried installing extra packages (qgis-plugin-grass, grass, saga) in
the Dockerfile, but it didn't help.
Here's my *Dockerfile*:
ARG QGIS_TEST_VERSION=latest FROM qgis/qgis:${QGIS_TEST_VERSION} RUN
apt-get update \ && apt-get install -y python3-pip qgis-plugin-grass
grass saga \ && rm -rf /var/lib/apt/lists/* COPY
./test/requirements.txt /tmp/ RUN pip3 install --upgrade pip || true RUN
pip3 install -r /tmp/requirements.txt || pip3 install -r
/tmp/requirements.txt --break-system-packages ENV LANG=C.UTF-8 WORKDIR /
This is my *run-docker-tests.sh*:
#!/usr/bin/env bash set -e pushd /usr/src/ibergis_qgis_plugin xvfb-run
pytest popd
And the relevant part of *GitHub Actions (test.yml)*:
# Run unit tests tests-qgis: runs-on: ubuntu-24.04
strategy: fail-fast: false matrix: qgis_version:
[latest, ltr, stable] env: QGIS_TEST_VERSION: ${{
matrix.qgis_version }} steps: - name: Checkout uses:
actions/checkout@v4 with: submodules: recursive
- name: Test run: | chmod +x
.docker/run-docker-tests.sh docker compose -f
.docker/docker-compose.yml run qgis
/usr/src/ibergis_qgis_plugin/.docker/run-docker-tests.sh
I haven't found much documentation on running QGIS plugin tests in CI
environments, so I might be missing something obvious.
If anyone has experience running tests that use Processing algorithms
inside Docker, I'd really appreciate some guidance.
Thanks in advance!
