I get this error while running pytest inside the container. What can be done to fix this error? I am able to run the same package from pycharm and from my Windows shell. That is after I set the PYTHONPATH.

ImportError while importing test module '/testsuite/comments_posts_api/test_put_comments_post_byid.py'.
Hint: make sure your test modules/packages have valid Python names.
Traceback:
comments_posts_api/test_put_comments_post_byid.py:6: in <module>
    from service_layer.post import Post
E   ModuleNotFoundError: No module named 'service_layer'

  • Can you run a shell into the container (you might have to remove the entrypoint) and make sure that the structure under /testsuite is what you expect it to be? If service_layer is a directory you might have to put another "/" after it in case you only want the files inside copied – Mihai May 06 '19 at 18:54
  • The directories are created properly. I ran pytest from the container prompt.This seems be some sort of a path issues. If you move the dependencies in the same folder, pytest works fine inside the container. – RSSregex May 06 '19 at 19:15
  • Maybe omit the /testsuite/ in the entrypoint. You are already in that directory because of WORKDIR. Maybe then the paths are picked up correctly – Mihai May 06 '19 at 20:20
  • ENTRYPOINT ["sh", "/docker-entrypoint.sh"] ? Like this. Got this error. PS C:\Users\test> docker run -it myapp:v0.1 /bin/bash sh: 0: Can't open /docker-entrypoint.sh – RSSregex May 06 '19 at 20:45
  • ENTRYPOINT ["sh", "docker-entrypoint.sh"] . This works as far as making it to the directory. But the pytest issue is not resolved. – RSSregex May 06 '19 at 20:47
  • What is the command in `docker-entrypoint` that runs the tests? Can you share the script contents? Also, check out answers to [this question](https://stackoverflow.com/questions/10253826). – hoefling May 06 '19 at 21:12
  • Adding this in my test folder solved. it. I got it from one of the postings here. __init__.py file import os import sys sys.path.insert(0, os.path.abspath(os.path.join(os.path.dirname(__file__), '..'))) – RSSregex May 06 '19 at 21:57
