[Distutils] How to test setup.py with easy_install?

So I've just added install_requires=["lockfile>=0.2"] to my setup() call. How do I test that from within my local source repository? Running "python setup.py install" doesn't seem to do anything with it (I didn't expect it to). I assume I have to get easy_install to process the setup.py file in the current directory somehow, but I don't see how. Thanks, Skip
