Testing Django Viewsets with Pytest

Testing your API endpoints is the single best way to ensure your web application remains secure, reliable, and functional as it grows. This text-based course guides you through the foundational concepts of testing Django viewsets, helping you write clean, automated tests that catch bugs before they reach production. You will start with the essential terminology of test-driven development, learn how to set up your testing environment, and understand how Django REST Framework handles requests and responses. What you will learn: Understand the core principles of API testing and how to structure test suites; Configure Pytest with Django for efficient and isolated test execution; Write tests for standard viewset actions including list, retrieve, create, update, and delete; Verify user permissions, authentication states, and custom access controls; Use fixtures to manage database state and mock external dependencies cleanly; Implement modern testing practices like parameterized testing for diverse inputs. We begin with the fundamental concepts of testing and HTTP requests before moving step-by-step through writing tests for every major viewset action. This course is designed specifically for beginners who have a basic understanding of Python and Django but are new to automated API testing. No prior testing experience is required.
