I currently don't see a good way to check xy point data ... i can use assert_xy but that data need to be manipulated for this to work prooperly. Ideally we'd have a assert_points in the vector testor that worked like lines and polys and accepted a GDF that could be used to test for the correct data.
i'll post more on this but homework 3 in ea python 2020 has perfect examples of where this would be used.
