It appears that the only testing for the LineCurrentFreeSpace is just in the documentation, it would be good to have tests that check accuracy as well. Here are a couple of ideas:
use a small segment (1m) and compare with the electric dipole in a whole space (away from that)
use a small closed loop (say 1m x 1m) and compare with a magnetic dipole in a whole space (again away from it)
It will take a bit of care to choose appropriate distances and tolerances, but I suspect that at about 10m the solutions should be nearly identical, and these could be tested for each orientation
