Subject: [geda-user] which test interface should I use?

I want to add tests for the geometry/drc cleanup I wrote.

It looks like there are two approaches already in use in pcb:

   * main-test.c to run tests via g_test interface of glib

   * pcb/tests has a setup to run pcb in batch mode and compare the
output to 'golden' versions

Are we trying to favor one or the other of these?

It's a toss-up which would be better as far as I can see.

The first would still need to start from input pcb files to be
convenient (so those would have to be added somewhere) and the result
would be less easy to hand-verify, but the changed interfaces could be
called more directly.

The second might yield a fragile test (since it just used diff with
golden file) and would require factoring test into Actions (so less
direct test), but would more easily generate a human-viewable test
result.

Britton.
