basedir not being added to sys.path for doctests

when I run py.test 2.0.3 in a project with this dir tree:

- projname  
  - module
    - __init__.py
    - ...
  - tests
    -  *.txt

if I run "py.test --doctest-glob='*.txt'" pytest doesn't add projname to sys.path, the error is that the tests can't import module. Even if I put a init.py in tests it still doesn't add the basedir in sys.path.

you need to do something like "python setup.py develop" to make your module importable and then run py.test.

This works fine in nose why not make it work in py.test? I know it depends on the cwd, but anything that help taking out the pain to run doctests seems like a good thing to me. And adding a init.py should make it add the parent dir to sys.path anyway and then it should work indepently from the cwd.

The general strategy is to require "python setup.py develop" or "pip install -e ." when running tests, for the tests to find the code they are supposed to test. Otherwise it becomes hard to run the tests against an installed package which is something where py.test shouldn't get in the way.
