Django Unit Testing

1 Add Test Suite

cd ~/my_blog_app
. env/bin/activate
cd ~/my_blog_app/blog/blogsite
mkdir tests
cd ~/my_blog_app/blog/blogsite/tests
touch __init__.py
# Model, View for testing
touch test_models.py
touch test_views.py
nano test_models.py

test_models.py

from django.test import TestCase

class ModelsTestCase(TestCase):
    pass

2 Test Code

cd ~/my_blog_app/blog/blogsite
nano models.py

models.py

class Post(models.Model):
    ...
    def save(self, *args, **kwargs):
        if not self.slug:
            self.slug = slugify(self.title)
        super(Post, self).save(*args, **kwargs)
    ...

test_models.py

from django.test import TestCase
from django.template.defaultfilters import slugify
from blogsite.models import Post


class ModelsTestCase(TestCase):
# Test if posts have Slug value
    def test_post_has_slug(self):
        """Posts are given slugs correctly when saving"""
        post = Post.objects.create(title="My first post")

        post.author = "John Doe"
        post.save()
        self.assertEqual(post.slug, slugify(post.title))

assetEqual

• checks whether slug for post is correct.
• Two Arguments are passed and equality is determined "=="
• raises error if not equal

3 Django's Test Client

test_views.py

from django.test import TestCase


class ViewsTestCase(TestCase):
    def test_index_loads_properly(self):
        """The index page loads properly"""
        response = self.client.get('your_server_ip:8000')
        self.assertEqual(response.status_code, 200)

4 Run Test

cd ~/my_blog_app/blog
python manage.py test
# RESULT
