CI is having dependency resolution issues w/ tests_require in python2.7 (e.g. see this build):
Not installing python2 compatible version of dependencies (e.g. installing pyparsing3.0.0a1, which is python3 only)
This PR explicitly enumerates test dependencies in a test section in extras_require and bumps the required version of pytest (required by new pytest-cov).
