Add CI/CD workflows?

[jamaa]

Using GitHub actions1,2, we could automatically test, build and deploy documentation and publish new releases.

Tests

If we have tests, we could run those on each push. Not sure what kind of tests would make sense for this plugin though. Maybe the following can serve for inspiration:

• some tests in a QGIS plugin: https://bitbucket.org/janzandr/rastertimeseriesmanager/src/master/test/
• workflow for testing with pytest: https://github.com/Weathermann/radolan2map/blob/master/.github/workflows/python-app.yml

Docs

Documentation could be built using Sphinx and hosted either on ReadTheDocs or Github pages.

• Example published docs: https://raster-timeseries-manager.readthedocs.io/en/latest/
• Example source files: https://bitbucket.org/janzandr/rastertimeseriesmanager/src/master/doc/
• Example workflow for building and publishing docs (not sphinx but maybe still useful): https://github.com/bluemodel/BlueM.Wave/blob/master/.github/workflows/docfx-build-publish.yml
• Sphinx related actions in the marketplace: https://github.com/marketplace?category=&type=actions&verification=&query=sphinx

Releases

Python package for publishing QGIS plugins: https://github.com/opengisch/qgis-plugin-ci
