New issue 198: localized conftest not run
https://bitbucket.org/hpk42/pytest/issue/198/localized-conftest-not-run

Jason R. Coombs:

In the [[https://bitbucket.org/yougov/pmxbot|pmxbot project]], there is a pytest test suite, and within that test suite are two conftest.py files, one at tests/conftest.py and another at tests/unit/conftest.py.

{{{

        test_util.py
        __init__.py
}}}

These tests run fine under pytest 2.2.4, but under 2.3.dev10 and 2.3.dev17, some tests fail. Specifically, the tests that depend on the funcarg as defined in [[/yougov/pmxbot/src/85020053dd0b/tests/unit/conftest.py|tests/unit/conftest.py]] will fail because the funcarg is not defined:

}}}

I read the changelog for changes between 2.2 and 2.3 and I didn't see anything that seemed to indicate that this pattern is no longer supported.

Can pytest support multiple, scoped conftest.py modules? I wanted to report this as it appears to be a regression from 2.2. The changelog should probably mention it (or if it already does, highlight the impact as I've described) if it is not supported. Do you have any other suggestions?
