Continuous integration & automated tests for a QGIS plugin in python

[klokan]

It would be great to setup GitHub Actions or Travis to test this QGIS MapTiler plugin.

This way all PRs would be validated - and we would be sure that the plugin runs in different versions of QGIS - from 3.4+ up.

Let's have a look around if other GPL plugins are doing this, to not start on a green field.

Would be nice if you could share your findings here. Feels like ages I wanted to look into this. Every time I do I mostly find out-dated instructions and overly-complex role models and give up again 😅
