Ahem! This looks like it is saying "run the difficult part that we are testing, but if anything goes wrong, just skip the test".
:-) Well, i tested on platforms where these invocations miserably fail because there was no matching C-compiler available and then they give long obnoxious tracebacks from within distutils somewhere.
The test *is* that t.ccompile() works correctly, and only additionally that calling the compiled function works. In practice it's more common that there is an exception-raising bug in genc.py, which is called by t.ccompile().
OK, from the containing "build_cfunc" function i didn't guess that the call to t.ccompile() was supposed to be a test by itself. I guess that either the Genc() part should be called separatedly or we should have our distutils invocations fail more cleanly and extend "skip_on_error" to require specifying an explicit Exception class. then the above could turn into py.test.skip_on_error(SystemExit, t.ccompile) which - hopefully - GenC() does not raise :-) cheers, holger
