OK. :-) I picked check after a brief survey of the available open-source
unit testing tools for C, and at the time I believe my experience with
unit testing was limited to a bit of JUnit. According to the commit
history, this was in 2004. It turned out that XCB is difficult to unit
test, so its use of check is pretty minimal, and I haven't touched it in
some time.

As I recall, check is pretty reasonable as a minimal unit testing
framework. It doesn't do too much but it does what it does well.

I'd suggest comparing with the test harness that's in the xserver tree
these days, and of course cairo's amazing test suite.
