arquivos py.test` e `init . py`

Eu penseipy.test é "autônomo" no sentido de tratartest_*.py files "como está" e importa apenas os módulos especificados nesses arquivos, sem considerar os arquivos ao redor. Parece que estou errado. Aqui está o meu diálogo compy.test:

$ ls
__init__.py    test_pytest.py
$ cat __init__.py 
$ cat test_pytest.py 
def test_pytest():
    assert True
$ py.test test_pytest.py

Como faço parapy.test trabalho e ainda tenho meu__init__.py arquivos

ATUALIZA

Nos comentários, Holger Krekel perguntou, qual é o nome do diretório pai. Acontece que eu posso reproduzir o erro acima apenas com um determinado nome de diretório pai (por exemplo, o mesmo nome de um dos pacotes instalados, comodistutils). Veja aqui

~/test_min 
$ tree
.
└── distutils
    ├── __init__.py
    └── test_pytest.py

1 directory, 2 files
~/test_min 
$ cat distutils/__init__.py 
~/test_min 
$ cat distutils/test_pytest.py

    assert True
~/test_min
