These are not tested in any geometry. Also note that there is nothing to test in here, values are hardcoded...

Most geometries are linear, therefore this is not even existing

Also note that there is nothing to test in here, values are hardcoded...

In that case test should be easy...

I checked it for the quadratic ones featuring the implementation of this method.

Easy but meaningless... Anyway, I'll try to figure out something.

You may have hardcoded wrong, that happened to me several times. In any case I will approve and I leave up to to you add the test or not.

@loumalouomega rather than checking hardcoded values, which IMO makes no point at all, I decided to create a fake isoparametric tet (so we avoid the Jacobian transformation complexities) and check the derivatives values with a second order field, expected to be constant over the entire element.
