I had a draft version like that. I thought the separate tables was a
bit nicer than having a bunch of true/false entries in the table that
you have to look elsewhere to interpret.

I guesss. Originally I was trying to maintain the test names, but now
that I've ended up changing them for other reasons, I guess that
doesn't matter.

Well, I was trying to avoid having conditionals at the end as well as
the beginning. But I just realised g_free(NULL) is safe, so that can
still be done. I'll update.
