setup: move test dependencies to dev_requirements.txt to make them optional Remove the need for having test tools on production systems. Installing test dependencies is made an extra explicit step. pip is the future, but doesn't have the same tests_require features as setuptools kind of has. I don't like this way of handling it without setup.py support and with explicit naming of the ugly dev_requirements.txt ... but that seems to be the way to do it.

[tox]
minversion = 1.8
envlist = py{26,27}-pytest

[testenv]
setenv =
    PYTHONHASHSEED = 0
deps =
    -r{toxinidir}/dev_requirements.txt
    py26-pytest: unittest2
    python-ldap
    python-pam
commands =
    pytest: py.test {posargs}
