Hi Eric,

Sorry if you receive this twice.

This works for me; I think you need to update your version of pytest:

py.test lib/matplotlib/tests/test_axes.py::test_hist_steplog
============================= test session starts
=============================
platform linux -- Python 3.5.2, pytest-3.0.3, py-1.4.31, pluggy-0.4.0
rootdir: /home/elliott/code/matplotlib, inifile: pytest.ini
collected 505 items

lib/matplotlib/tests/test_axes.py ...

========================== 3 passed in 3.78 seconds
===========================

Note, there are 3 tests because of the 3 extensions that are checked by the
image_comparison decorator.

This will not work at the moment. tests.py continues to use nose, so it
will not run pytest-based files. The list of files that only work with nose
is very short right now. As soon as my other PR is merged, I will open a PR
that should make this work again (there are conflicts).
