The Dev Guide should say the preferred way (or even a way) to run tests using the Python 2.7 build:

http://docs.python.org/devguide/runtests.html

This will help submitters who want to check that their patch works with 2.7.

In Python 2.7, this did not work (for obvious reasons):

$ ./python.exe -m test
.../python.exe: No module named test.__main__; 'test' is a package and cannot be directly executed

But this did:

$ ./python.exe -m test.regrtest

Is the latter the preferred way?
