You don't have to literally cd there - using any path that points to the
"build copy" of the program or test works.

Anything that needs the compiled extension can't possibly work without
building first, anyway. And although one could theoretically run tests
based solely on pure Python code without building, it's not worth the
hassle to special-case that. None of the C tests runs without building
The real problem with fitting the tests into waf's testing framework is
that the latter just plain doesn't handle Python tests properly (and you
can find grumbling online about that). Fixing this requires figuring out
why it doesn't work and coming up with some sort of workaround.
In the meantime, you can make do with:
$ ./waf configure && ./waf build && for t in build/main/tests/pylib/test_*.py; do $t || break; done
BTW, all the waf code is readable once it's been run, in the .waf-...
directory. You can even set breakpoints in it if you first break at the
Scripting.waf_entry_point() call in ./waf (currently line 165, but that
