First you have to make the test class known to the setup-script:

setup(...,
      cmd_class = {'test': test},
      ...)

This allows to run 'python setup.py test', and since the
'run' method of the test class contains a call to build
self.run_command('build'), the build step will be run first,
and then your test.

If you want the 'test'-step always be run at the end of the
build-steps, you can install 'test' as a sub-command of build
(Remove or comment-out the "self.run_command('build')" line
before trying this, otherwise test and build would call each other
recursively) in this way:

from distutils.command import build
build.build.sub_commands.append(('test', None))

setup(.....)


You could replace the 'None' above by a method test.has_tests()
for example which would answer true if there are test cases,
false otherwise.
