Running tests first time to check Django installation

Using Django Mystery Errors
1

This is my first time working on this project. I followed all the steps to setup Django locally. But when I run runtests.py, one test is failing. I tried reinstalling everything from strach but it is still not working.

Hi samruddhiDharankar! Please see this topic for some potential advice: Error/Failure in Django local clone steup

Hi @samruddhiDharankar I’m Adya, I have faced exact same error: django.db.utils.OperationalError: no such table: test_utils_car

What’s your OS? I think the issue is related to Django i18n and SQLite Database.

You can try unit tests Unit tests | Django documentation | Django to confirm exact issue.

I solved my issue by doing iteration unit testing, checking my venv, and I also had to change my OS

I think this command will help you to understand the error in detail

python manage.py test test_utils --verbosity=2

python runtests.py i18n --verbosity=2

for Unix: ./runtests.py i18n

I recommend this doc to you too:

All the best :slight_smile:
