Can py.test test docstring for the numpy style?

My pytest.ini currently looks like this:

[pytest]
addopts = --doctest-modules --cov=. --cov-report html --pep8 --flakes
doctest_encoding = utf-8

So I already test for PEP8. But I would also like to test the docstrings for numpydoc format:

• Are all parameters named in the correct order?
• If there is a return statement, is there also Returns in the docstring?
• ...

Is this possible
