doctest modules or doctest files ("test_*.txt")?

Works for me.  Just tried a conftest.py like this:

    import pytest

    def pytest_runtest_setup(item): 
        pytest.set_trace()

and in the same dir a doc.txt like this:

    >>> 3
    4

and then run "py.test -s" which invokes the setup hook
using pytest-2.0.0 for me.

Not sure if this is sufficient for your setup purposes, though.  
Do you want to inject custom objects into the namespace
for your doctests by chance? 

If so you might want to look into

    https://bitbucket.org/hpk42/pytest/src/88c0e00cfe8b/_pytest/doctest.py

and enhance it to suit your purposes (pass "extraglobs") and then submit back
the mods including a test.   

On a more general note, it actually makes might make
sense to port the way nose is doing it, see here:
