Automating PUT Requests in REST API Testing with Rest Assured

Testing how an application updates existing data is a critical part of ensuring API reliability, yet managing state and payload validation can be challenging. This course guides you through the process of automating HTTP PUT requests to seamlessly update records. You will transition from manual API testing to writing clean, automated Java tests that verify your data updates correctly every time. What you'll learn: - Understand the core concepts of RESTful APIs, HTTP methods, and how PUT requests differ from POST and PATCH - Configure Rest Assured in your Java environment using modern build tools and dependency management - Structure dynamic request payloads using Java objects and serialization techniques - Validate API responses by asserting status codes, headers, and JSON body content - Implement clean code practices and basic assertions using modern testing frameworks like JUnit or TestNG - Handle authentication and error scenarios to ensure your automation suite is resilient You will begin with essential API terminology and HTTP foundational concepts before moving step-by-step through setting up your environment, writing your first PUT request, and validating complex payloads. This text-only course is designed specifically for beginners with basic Java knowledge and no prior API automation experience. Start building your automated API testing skills today.
