you can ensure python_on_whales is installed by using the "docker" extra (i.e. pip install pytest-mock-resources[docker]

from pytest-mock-resources.

the fixture is returned directly from create_redis_fixture(), so you would replace your fixture with it. like so:

redis_client = create_redis_fixture()

@pytest.fixture
def redis_client2(redis_client):  # or if you want/need to create your own client object from credentials
    yield Redis(**redis_client.pmr_credentials.as_redis_kwargs())

from pytest-mock-resources.

@DanCardin thanks for the feedback. Here's an updated test_myapp.py that works:

from unittest.mock import patch
from pytest_mock_resources import create_redis_fixture
from myapp import set_item, REDIS_KEY

redis_client_fixt = create_redis_fixture()

def test_set_item(redis_client_fixt):
    with patch('myapp.REDIS_CLIENT', redis_client_fixt) as redis_client:
        idx = 1234
        value = b"some_value"
        set_item(idx, value)

        assert redis_client.hget(REDIS_KEY, idx) == value

It's worth mentioning that the module python_on_whales had to be installed (python -m pip install python-on-whales) and a redis Docker image was pulled the first time the test ran.

from pytest-mock-resources.
