Practical Automated API Testing

In today's interconnected digital world, APIs are the backbone of modern software. Learning how to test them effectively is a critical skill for ensuring applications are reliable, secure, and performant. This course provides a complete foundation in automated API testing, from the fundamental concepts to writing your first automated test suite. You will gain the practical skills to confidently test any RESTful API, validate responses for correctness, and build a repeatable process for quality assurance that integrates into any modern development workflow. What you'll learn: - Understand core API concepts, HTTP protocols, status codes, and common data formats like JSON. - Practice manual API testing and exploration using Postman to inspect requests and responses. - Build automated test scripts in Python using the 'requests' library to interact with APIs programmatically. - Learn to structure tests, write clear assertions, and manage test suites effectively using pytest. - Apply common authentication patterns, such as API keys and bearer tokens, in your test scripts. - Design effective test cases that cover happy paths, edge cases, and error conditions for comprehensive coverage. The curriculum begins with the essential theory of APIs and web communication, then moves to hands-on exercises with industry-standard tools, and culminates in building a structured, automated test project from scratch. This course is designed for absolute beginners. No prior experience in API testing or automation is required, though a basic familiarity with any programming language is helpful.
