Can I use single conftest.py for different test directories?

Question

Here is my test directory:

test/
    unit/
        some test files 
        conftest.py
    acceptance/
        some test files
        conftest.py

Right now there are two conftest files for fixtures. Can I combine them into one conftest.py file? If yes, where should I keep that common conftest.py?

Answer 1

You can combine the fixtures into a conftest.py file within the top-level test directory. Per this documentation, conftest files are per directory. The conftest file (and fixtures and plugins therein) should be available to test files in that directory and in child directories. If you do that, I recommend making your test directory into a python package by adding a __init__.py file (per the note in this documentation).
