Is pytest-mock-resources timing out or hanging? or what does "dont start" mean.
I know in the past i've needed to docker pull redis:5.0.7 ahead of running the tests due to slow network speed. if you dont have the image in question ahead of time it will pull it and potentially introduce longer startup time than we allow for in our timeouts.

Thanks for your answer
The Image is already on my system.
The package throws the exeption below. And if i watch docker desktop gui the container dont start (and it did before the update).
The exception says redis cant connect but i belief the problem is that the container is not started.

Perhaps a docker system prune -a? If it's failing to spin up the container at the docker level, it's beyond the scope of what PMR can affect the outcome of. Particularly if it was a Docker Desktop upgrade, that pretty much guarantees it's unrelated to the inner workings of this library.

pruning the system doesnt fix it. And i have the same error on the new notebook of my colleague.
Did you have any idee?

The only other thing I can think of is that the host correct for your docker setup. If you can import python_on_whales or docker-py, construct a client yourself, and create a container yourself, then it's almost certainly that you need to explicitly export the PYTEST_MOCK_RESOURCES_HOST env var to a different value.
If that doesnt work, then the problem is definitely outside PMR itself.

That's what I do last week. I use pytest-docker and create the Redis service with this as a fixture. 👍
I wish you a Merry Christmas and a happy new year.
