As this is a followup for #1244, this commit should be part of that PR (you can update the PR by cherry picking this commit into the branch, that backs the PR and push it.

Thank you.
As this is my first contribution, I've edited these two fragments on github (and should learn better how to work with branches and pull requests).
I cannot cherry pick on github, right?

You can update PRs by pushing new commits into the branch that was used to create the PR. That even works if you force-push. In your checkout do this:

# switch to patch-1 branch
git checkout patch-1
# cherry-pick the tests into this branch
git cherry-pick 8becb206246d4b01dd18095d50621acb150a3a82
# Run unittests and see if everything works
# Push updated branch - this assumes your first push of patch-1 set the github branch as upstream
git push

On github you will now see two commits in the "Commits" tab. By this time you can close #1248 as the code lives in this PR.

Thanks a lot for your advice, followed your instructions and had fun learning more how to git and github.
Cherry picked to patch-1, closing.
