Django — Testing

Basic Test

# blog/tests.py
from django.test import TestCase
from django.urls import reverse
from .models import Post

class PostTestCase(TestCase):
    def setUp(self):
        Post.objects.create(title='Test Post', content='Test content')
    
    def test_post_creation(self):
        post = Post.objects.get(title='Test Post')
        self.assertEqual(post.content, 'Test content')
    
    def test_post_list_view(self):
        response = self.client.get(reverse('post-list'))
        self.assertEqual(response.status_code, 200)

Test Client

class ViewTests(TestCase):
    def test_get(self):
        response = self.client.get('/blog/')
        self.assertEqual(response.status_code, 200)
    
    def test_post(self):
        response = self.client.post('/blog/create/', {
            'title': 'New Post',
            'content': 'Content'
        })
        self.assertEqual(response.status_code, 302)

Run Tests

python manage.py test
python manage.py test blog
python manage.py test blog.tests.PostTestCase

Mini Practice

1. Write model tests
2. Write view tests
3. Use test client
4. Run test suite
