@slarosa any reason to use mocked QGIS app for the tests? I intentionally used QGIS testing class to promote @m-kuhn 's work last year. Though Boundless makes another testing framework using docker with QGIS instance inside (so the tests are run against a real QGIS instance) and people start using this last approach more...

[m-kuhn]

QGIS upstream also uses docker images for testing QGIS 3. This can also be used for plugins (see e.g. https://travis-ci.org/opengisch/projectgenerator), QGIS testing classes are available as well.

[slarosa]

No particular reason, just want to see travis happy :-) against more qgis version!
I will do a PR with docker image for testing as soon as possible taking inspiration from @m-kuhn's hint! Thanks.

@slarosa

You get extra points if you make a deploy

• on success of all builds
• and when it's a tagged release

;)

@m-kuhn and that should be an awesome score for my unit-testing game! :-p

[akbargumbira]

@m-kuhn is there docker image for QGIS 3?

@slarosa more extra points if there is a QGIS 3 image and we also test it against this version :) @elpaso started some work to port this to be ready for QGIS 3 as a core plugin in this branch: https://github.com/akbargumbira/qgis_resources_sharing/tree/qgis3, but I haven't got time to finish it

[m-kuhn]

@m-kuhn is there docker image for QGIS 3?

The one from the link above is qgis3.

One of the two does not change (fixed to a certain commit) the other one regularly gets updated to the latest master.

@slarosa any reason to use mocked QGIS app for the tests? I intentionally used QGIS testing class to promote @m-kuhn 's work last year.

Also, using the QGIS testing module (see slarosa@0abda99) I got a bunch of ImportError (i.e ImportError: No module named qgis_resources_sharing.test.repository_handler.test_handler), but was unclear to me on what could be the reason of the problem there:

This PR has long lived and tests have been refactored to fit Github Actions in #259.
