Reuse pytest fixtures

I am writing some tests using pytest many of which have similar fixtures. I want to put these "global" fixtures in a single file so that they can be reused across multiple test files. My first thought was to create a fixtures.py file such as

import pytest


@pytest.fixture()
def my_fixture():
    # do something

Now how do I use this fixture in my_tests.py?

def test_connect(my_fixture):
    pass

This gives fixture 'my_fixture' not found. I can from fixtures import my_fixture. What is the suggested solution to this situation?

Fixtures located in a conftest.py file have vectical scoping with respect to the visibility of the fixture variable to test modules. This means that all test modules located as a sibling in the directory where the conftest.py file is located, or any subdirectories beneath that directory can all see the fixtures present in the conftest.py module.

That is a particular form of reuse but not always desired. If you want to reuse horizontally across test projects located in entirely different folders then you must put the fixtures within a "plugin module".

Take a look at these answers to get a sense of the possibilities

Pytest will share the fixtures in conftest.py automatically. Move the shared fixture from fixtures.py to conftest.py.
