Testing Django with Model Mommy

I am running into an issue where I have my test passing locally, but when running on CircleCI I am not passing the tests.

The test are failing in a way that would suggest the models are not being properly created using ModelMommy. I have confirmed this, by removing the model mommy definitions, and running my tests locally again to see the same errors that are cropping up on my CircleCI integration.

I am running the same test command locally, as is being run on CircleCI.

Am I missing a setting that lets CircleCI create temporary models?

Thanks for any help.

Stack I’m using:
Python
Django
Model Mommy

Error I’m seeing:
> assert response.status_code == 200 E AssertionError: assert 302 == 200 E + where 302 = <HttpResponseRedirect status_code=302, "text/html; charset=utf-8", url="/">.status_code
Where this works correctly on my machine when testing, and is not a redirect. I can make it a redirect if the model definition using ModelMommy does not exist. This is because one of my views does a redirect to the home page in the event that the model does not exist.

Which troubleshooting steps you’ve already taken:

  • Re-run without cache
  • Tests passing locally
  • Running tests locally without model mommy - causes similar issues, but not convinced that is an exact indicator of why this isn’t working on CircleCI
