Invoke pytest from python for current module only

Question

I know that py.test can test a single module if I do:

py.test mod1.py

Or, I can invoke pytest inside python:

import pytest
pytest.run(['mod1.py'])

Can I do it inside python, and let it to run the current module? I guess I can do:

import pytest
import os
pytest.main([os.path.basename(__file__)])

But wonder whether this is the most "pythonic" way to do it. Thanks!

Your versions do not allow passing extra arguments to pytest (e.g. allow ./test_file.py -v). I tried simply

import sys


if __name__ == '__main__':
    pytest.main(sys.argv)

and it seems to do the trick. sys.argv[0] is the script name (i.e. __file__, possibly as a relative path), so it restricts the call to the script, and sys.argv[1:] contain extra arguments passed on the command-line.

Any better idea appreciated!
