In the examples I’ve used so far in this series , tests only are using at most one named fixture.

You can use more.

Simple example:

import pytest

@pytest.fixture(scope="module")
def foo():
    print('\nfoo setup - module fixture')
    yield
    print('foo teardown - module fixture')

@pytest.fixture()
def bar():
    print('bar setup - function fixture')
    yield
    print('bar teardown - function fixture')

@pytest.fixture()
def baz():
    print('baz setup - function fixture')
    yield
    print('baz teardown - function fixture')

def test_one(foo, bar, baz):
    print('in test_one()')

def test_two(foo, bar, baz):
    print('in test_two()')
$ pytest -s test_multiple.py
