Testing Django REST Framework with Pytest 1. Django REST Framework is a wrapper over default Django Framework, basically used to create APIs of various kinds. You can detect the anomaly earlier and you can decide how your API should behave with the certain input. For compatibility with Django's existing RequestFactory the default format is 'multipart'. This package provides a RecursiveField that enables you to serialize a tree, linked list, or even a directed acyclic graph. REST framework will attempt to authenticate with each class in the list, and will set request.user and request.auth using the return value of the first class that successfully authenticates.. The APIRequestFactory class supports an almost identical API to Django's standard RequestFactory class. However, even when I'm authenticated, I still get 401 UNAUTHORIZED every time. Since the project requires me to follow Test-driven-development (TDD) paradigm, i have to write the test for my Django REST apps. NOTE: in the example I'm using the warlus operator from Python 3.8.. Wrapping up. It will help you to build conceptual knowledge and confidence. To unauthenticate subsequent requests, call force_authenticate setting the user and/or token to None. For example, it's easier to inspect response.data: Instead of inspecting the result of parsing response.content: If you're testing views directly using APIRequestFactory, the responses that are returned will not yet be rendered, as rendering of template responses is performed by Django's internal request-response cycle. Testing Django Rest Framework APIs. Before you get started. Methods which create a request body, such as post, put and patch, include a format argument, which make it easy to generate requests using a content type other than multipart form data.
