Hands-On API Testing with Python, HTTPX, and Pytest

In modern software development, APIs are the backbone of application connectivity, making robust automated testing a critical skill for quality assurance. Testing APIs manually is slow and error-prone, but Python offers a powerful, modern ecosystem to automate this process. This text-based course guides you from the absolute basics of HTTP protocols to writing clean, automated API tests. You will learn to use HTTPX—the next-generation HTTP client—alongside Pytest to validate responses, handle authentication, and structure scalable test suites. What you'll learn: - Understand the foundational concepts of REST APIs, HTTP methods, status codes, and headers. - Write automated HTTP requests using HTTPX to interact with external web services. - Create structured, reusable test cases using the Pytest testing framework. - Validate complex JSON response payloads using modern data validation techniques. - Handle advanced testing scenarios including token-based authentication and query parameters. - Apply asynchronous testing patterns with HTTPX to execute test cases efficiently. You will start with essential web terminology and basic HTTP mechanics before moving step-by-step into writing test assertions, managing test configurations, and validating real-world API endpoints. This course is designed for beginner QA engineers, manual testers transitioning to automation, and developers looking to master API testing with Python. No prior automation experience is required.
