Thanks for the pointers and interest. I'm certainly interested in seing solid testing and

Not yet, but there will be definitely tests.

Where is GIGS described ? I couldn't find much online documentation. I do see proj has now a
test/gigs directory with tests converted to the .gie format, but I couldn't find the source

Python bindings over what ?

I guess the GeoAPI tests would be needed to be ported/adapted to whatever solution is
adopted for proj testing. I don't really feel like using the proj JNI wrapper through Apache SIS
would be an ideal solution : too many components aggegated, and I'm not sure if JNI wrapper
will have all the new capabilities exposed.
