how do I run setuptools_scm test suite locally?

[anthrotype]

I'd like to submit a PR to fix another issue, but I'm having hard times figuring out how to run the test suite for setuptools_scm locally on my machine.

I have python 2.7.13 and 3.6.1 installed globally, each has tox installed.
Any of these commands make pytest fail with a RuntimeError: maximum recursion depth exceeded error.

python2 -m tox -e py-test
python3 -m tox -e py-test
tox -e py27-test
tox -e py36-test

I'm probably missing something very basic. In that case, sorry for the noise.

Thanks.

FYI, I am using the latest pytest 3.1.2 and tox 2.7.0.
The setuptools version is 36.0.1.

@anthrotype please try to run them in a own virtualenv - at first glance it looks like a pytest report and i#ll log it into pytest issue tracker

@anthrotype note that you will need to downcrade py.test

@anthrotype it seems that you hit pytest-dev/pytest#2501
