Thanks - I'd looked at these and thought it was a pure text format, and so hard to edit. Now I see you specify an sgf file and move in that file, so really it is just a separation of the test position from the test and result.The GNU Go sources contain regression tests in GTP (Go Text Protocol) form, with correct answers marked in the comments of the GTP files.
However, this test suite is developed and maintained only with GNU Go inYes - it seems many of the choices return gnu go function return values.
mind.
