Unit tests are automatically executed after every commit made to the repository. Results are available for:
To run the tests locally you need to have docker and docker-compose installed. We suggest to:
- Download docker from the official site. For instance, for Ubuntu / Linux_Mint follow the steps in Install using the convenience script.
- Install docker-compose using the binaries.
- NOTE: installing Docker on Ubuntu 20.04 is easier.
Before running unit tests, you need to set these 2 environment variables (make sure you use your own repository's root path for the first one; the second one corresponds to an official QGIS Docker Hub's tag):
export GITHUB_WORKSPACE=/home/Asistente-LADM-COL
export QGIS_TEST_VERSION="final-3_22_1"
The command to execute unit tests is (execute from the repository's root folder):
docker-compose -f .docker/docker-compose.yml run --rm qgis
If you need to recreate the docker image, you can use:
docker-compose -f .docker/docker-compose.yml down --rmi local && docker-compose -f .docker/docker-compose.yml build
The LADM-COL Assistant uses QGIS Tester plugin to support assisted tests for GUI functionalities.
Prerrequisites:
In order to run the assisted tests, you need to install:
- QGIS Tester plugin (available at: https://github.com/planetfederal/qgis-tester-plugin).
- qgiscommons library:
pip install qgiscommons
See the docs for usage instructions.
If these prerrequisites are not met, the LADM-COL Assistant will continue running smoothly and will put a warning in the QGIS log.
