I doubt the ON_X_EVENT will handle all the cases we need, since it isn't
designed for surface/surface or point/anything cases, but since openNURBS
removed their version anyway I don't see why we couldn't extend it to meet
our full needs in libbrep, if that looks like a good way to go.
As for visualizing results in MGED (which I agree is desirable) I would
suggest having the test programs write out a .g file containing the inputs,
the expected output, and whatever was obtained instead in the case of a
failed test - test#_failed.g or some such naming convention would be needed
to keep them straight. That way, you can open that .g file and use the
brep command to visualize whatever needs visualization (for points, you
could just insert a sphere, and the rest I imagine could be represented as
invalid BReps, similar to the surface currently stored in
src/librt/tests/nurbs_surfaces.g. Eventually it probably will make sense
to have an interactive command for such operations in MGED, but I think the
unit tests are more critical initially.

Sounds good - that will mean your tests should live in src/librt/tests,
rather than src/libbrep/tests
