Why my pytest-deadfixtures is running outside indicated folder

[tamercuba]

I have a python app with the following folder structure:

├── src
└── tests
    ├── __pycache__
    ├── application
    └── integration

and im trying to run pytest-fixtures only inside the tests/application folder.

When I run pytest --dead-fixtures tests/application/ I get this output:

╰─$ pytest --dead-fixtures tests/application/                                                                                                                                                                                                                                      2 ↵

Cool, every declared fixture is being used.

What am i doing wrong so that pytest runs this check on my .pyenv folder?

My project is in ~/Documents/project_name and my pyenv root is ~/.pyenv

I'm not exactly sure what do you mean by "runs this check on pyenv folder."
The warnings are related to Python packages in your environment. None of those warnings are related to pytest-deadfixtures.
No matter what folder is the target, it will be executed using the Python environment available/active at the moment.
