Test works on local machine but in Docker I get "no module named 'test' "

[NiklasRz]

I have a pytest.ini and a test_something.py file in the same dir as my manage.py. If I run 'pytest' directly, it works. If I run the whole thing with docker-compose, get an interactive console on the docker container and run 'pytest' there, I get:

Any idea what might be the problem here?

[pkimber]

Just to say, I am getting the same issue. Did you find a solution?

[pkimber]

I am finding the issue in a Django project (which is the same as you I guess).
I solved the issue by copying manage.py into the root folder of my project.

[mohitCodepy]

@pkimber , I also resolved my issue by doing same.

Beyond this being a question with insufficient detail supplied; this should be closed as its in no way related to this project; this kind of question belongs on a place like stack overflow or even better one of the linux related stack exchanges.

That being said;

1. somehow copy all of the files to your docker WORKDIR
2. install your requirements.txt (probably what OP is missing) with pip

OR you can check out one of the many examples of using python/docker in my repository history. I have a python dev image i've been using to code on for several years now if you need some concrete guidance.
