`poetry run pytest tests` cannot import current project if tests/init.py does not exist

See original GitHub issue

Ran into this with Poetry 0.8.6. To reproduce this, you can delete tests/__init__.py in the Poetry project itself, then run poetry run pytest tests. On commit 4829967a37fc74b3b7715986867fbd2ade29b514, I get 25 failures on ModuleNotFoundError: No module named 'poetry'. Pytest doesn’t normally require __init__.py files, so this is surprising.

It looks like you need to do poetry add --dev pytest for it to work with poetry run pytest tests/. Otherwise it will not be adding your project folder to the PYTHONPATH

This works correctly in the latest version of Poetry (0.12.4). Looks like the fix came from 0.12.0 installing the current project in editable mode when you run poetry install, so now Pytest can find the current project without needing the project folder manually added to PYTHONPATH.
