ValueError: Internal error - config has not been correctly loaded. Over 3.2.1

Since pytest-cases 3.2.1 I'm getting the following error:

----------------
- Testing code -

Steps to reproduce

git clone https://github.com/lyz-code/repository-orm
cd repository-orm
make install
make test # pytest-cases 3.1.1 -> Works
pip install pytest-cases==3.3.0
make test # Error is shown

I've tried debugging it without success. Can you please help me?

Thanks!

Thanks @lyz-code ! This seems to be caused by usage of cases in the conftest.py.

I found out that conftest.py files are loaded before the pytest_configure hook. I'll fix this now by simplyreading the early config in pytest_load_initial_conftests hook instead.

Fixed in 3.4.4. Let me know if this works for you ! Thanks again for letting me know

[lyz-code]

Yes it did! thanks for the quick fix :)
