Unit Testing

Updated development dependencies:

echo -e "pytest\npytest-django" >> requirements-dev.in
pip-compile --output-file requirements-dev.txt requirements-dev.in
pip install -r requirements-dev.txt

Create setup.cfg in repository root:

echo -e "[tool:pytest]\nDJANGO_SETTINGS_MODULE=djangor.settings" >> setup.cfg

Create polls/tests/test_dummy.py:

import pytest
from django.contrib.auth import get_user_model

from polls.models.questions import Question
from polls.models.choices import Choice

User = get_user_model()


@pytest.mark.django_db
def test_dummy(client):
    question = Question.objects.create(
        author=User.objects.create(),
        text="What's up?",
    )
    question.choices.create(text='The roof')
    question.choices.create(text='The sky')
    assert User.objects.count() == 1
    assert Question.objects.count() == 1
    assert Choice.objects.count() == 2
    assert len(str(User.objects.first().pk)) == 36
    assert len(str(Question.objects.first().pk)) == 36
    assert len(str(Choice.objects.first().pk)) == 36

# TODO: parametrize by model

Run tests:

pytest

# if later your tests start to get slow...
pytest --reuse-db
