"""This module asserts correct runtime behaviour of the :mod:`pyrate.plan.geometry.helpers` functions
for translation.

Note that most of the correctness is asserted by the use in
:meth:`pyrate.plan.geometry.PolarPolygon.translate` and :meth:`pyrate.plan.geometry.PolarRoute.translate`.
Also, no extensive tests are needed since we trust the underlying library due to its widespread adoption and
maturity.
We only need to check that the conversion of parameters and results works as expcted.
