+"""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.
