Issue Module Import py.test

[oliveralka]

I stumbled over an issue that the tests running by py.test, would not be able to import modules - I am actually not sure why. After removing the __init__.py from the tests directory, all modules could be imported without any issues.

I just wanted to report it, if anyone else runs into the same issue.

py.test ./tests

python 3.8 MacOS 15.5.5
