from rest_framework.test import APIClient client = APIClient() # Force login as a user with ID = 1 client.force_login(user=User.objects.get(id=1)) # Create a new blog post response = client.post('/api/posts/', { 'title': 'My New Blog Post', 'content': 'Lorem ipsum dolor sit amet...' }) # Assert the API response self.assertEqual(response.status_code, 201)In this example, we create a new APIClient and use the force_login method to simulate the authentication of a user with ID = 1. Then, we make a POST request to the '/api/posts/' endpoint to create a new blog post with a title and content. Finally, we assert that the response status code is 201 to ensure that the blog post was created successfully. Overall, the rest_framework.test APIClient is a powerful tool that allows you to easily test your RESTful API endpoints in Django. Whether you need to simulate user authentication, send GET or POST requests, or assert the API response, this package library has everything you need to get started.
