What's the magic formula for regression-testing a single module?

What's the magic formula for regression-testing a single library module? I found a bug in ConfigParser -- the readfp() and write() functions are not perfect inverses in some situations. I think I have a fix, and want to verify correctness. -- <a href="http://www.tuxedo.org/~esr/">Eric S. Raymond</a>

I typically do: ./python -E -tt ./Lib/test/regrtest.py test_strptime Replace test_strptime with the test(s) you want, presumably test_cfgparser. Neal
