API Automation: File Uploads with Rest Assured

Automating file uploads is a critical yet often overlooked aspect of API testing. Many testers struggle with multipart requests, boundary configurations, and validating the server's response. This course provides a clear, text-based path to mastering file upload automation in your REST API testing workflows. You will transition from manually testing file attachments to writing clean, reliable, and automated Rest Assured scripts. By understanding the underlying HTTP protocols, you will be able to handle single and multiple file uploads, set correct content types, and assert response payloads with confidence. What you'll learn: - Understand the core concepts of multipart/form-data and how file uploads work at the HTTP level - Configure Rest Assured to send single and multiple files in a single POST request - Validate API responses, HTTP status codes, and server-side file creation details - Apply modern clean-code practices in Java to keep your API test scripts maintainable - Handle common upload errors and debug payload issues using built-in logging filters - Structure your test assertions to verify file metadata and upload success criteria This course begins with foundational concepts, establishing a clear understanding of multipart requests and REST API architecture. From there, you will progress through practical, written code examples that demonstrate how to construct, execute, and assert file-based API tests step-by-step. This course is designed for quality assurance engineers, automation testers, and developers who already have a basic understanding of Java and API testing, but want to master file upload scenarios. No prior experience with multipart automation is required. Start writing robust file upload automation scripts today.
