Some tests fail when py.test has a different name

[lgbaldoni]

Trying to package sphinx-argparse for openSUSE Tumbleweed and I've stumbled into a small problem.

To invoke the test we use a macro that cycles through the various python incarnations (2, 3 and pypy) and consequently each py.test executable comes with a different suffix.
Unfortunately it looks like that test/test_parser.py has a hardcoded py.test name and takes exception to things being otherwise.

Do you see a way around this?

OK, so this is rather awful hack how to deal with the problem:

(and of course you have set environmental variable PYTEST_NAME).

I made a less awful fix in d7a8384 (part of #113), could you test it and see if it solves the problem for you too?

[lgbaldoni]

@qha works for me

Thank you for the confirmation!
