You cannot test a binding, it is not possible. Otherwise explain me how
did you copy it to the device and what sort of device runs YAML.

The tag was given here explicitly, so I really do not understand this. I
could imagine tags coming from a reply to the cover letter, but adding
tag here? That's just fake test.
