@pdpinch requirements.txt that I have now include all things needed to run tests.

tests_require=["pytest-cov>=1.8.0", "pytest-pep8>=1.0.6",
"pytest-flakes>=0.2", "pytest>=2.6.3",
"httpretty>=0.8.3", "flask>=0.10.1",
"oauthlib>=0.6.3", "semantic_version>=2.3.1"],
install_requires=["oauth>=1.0.1", "oauth2>=1.5.211",
"httplib2>=0.9" ],

It makes sense to me to add all test requirements to the requirements.txt as it allows a contributor to run tests as well. Installing library requires only oauth, oauth2 and httplib2 (which is required by oauth2, but we noticed that occasionally does not install so it's added to our requires).
