Test header checkjacobians.hh is not used
There is a header dune/grid/test/checkjacobians.hh
in dune-grid that is supposed to check the Jacobian-related interface of a geometry. However, this header is not included anywhere in the core. I also could not find any use in a grid implementation.
The header was introduced in 2015 (99990bf9) by renaming checkjacobians.cc
. But even in this revision I cannot find any usage of it. Since then it has seen some cosmetic changes, but they all may originate from systematic grep&renaming procedures.
Since the geometry-interface is checked by checkgeometry.hh
in from dune-geometry I wonder if this header is obsolete.
