django.core.exceptions.ImproperlyConfigured: Requested setting MPTT_DEFAULT_LEVEL_INDICATOR, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing setting

[Roger Reyes]

Hello how are you? I am creating an Ecommerce and I am using Django-MPTT for the hierarchy in my model for the categories, I am also using pytest, and when I try to run the tests I get this error:
django.core.exceptions.ImproperlyConfigured: Requested setting MPTT_DEFAULT_LEVEL_INDICATOR, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings.

I made sure that all the settings in my settings were correct, but the error still persists. Has anyone had something similar happen to them?

You'll likely want to also use the pytest-django package too and then configure the Django settings using one of these approaches:

Excellent, I was able to solve the problem with the following command to run the tests: DJANGO_SETTINGS_MODULE=nameapp.settings pytest. Thank you Jaime!
