Ran 104 tests in 9.625s
FAILED (SKIP=18, errors=26, failures=3)

There are still some failing plugins tests. I'm going to continue working on it

[Lucas-C]

The situation is getting really better !

Ran 123 tests in 16.904s

FAILED (SKIP=7, errors=5, failures=1)

The remaining failing tests are due to the image_process & multi_neighbors plugins, for which there are already PRs created in the corresponding git repos, and listed in the checklist above.

At this point, I opened https://github.com/getpelican/pelican-plugins/pull/1210 in order to exclude those 2 plugins in the CI and pass it green

For the record, you can remove assets, image_process, similar_posts and thumbnailer from your survey. All have been moved to their own repositories at https://github.com/pelican-plugins . Better yet, all tests are passing there ! :)
