Automated Visual Testing with Selenium and TestNG

Functional tests tell you if a button works, but they often fail to detect if that button is overlapping text or hidden behind another element. Visual regression testing fills this critical gap in the quality assurance process by ensuring your user interface looks exactly as intended. You will transition from manual UI inspections to a structured automated workflow that identifies pixel-level discrepancies across your web application. By the end of this course, you will be able to detect unintended layout shifts and styling bugs before they reach your users. What you'll learn: - Understand the core concepts of visual regression testing and baseline management - Configure Selenium and TestNG to capture and compare web page screenshots - Apply modern selector strategies to ensure stable and reliable visual assertions - Analyze visual difference reports to identify unintended UI changes - Implement responsive design checks to verify layouts across different screen dimensions - Practice integrating visual checks into a modern continuous testing workflow The course begins with essential terminology and foundational definitions of visual automation before moving into the practical logic of screenshot comparison and reporting. You will read through detailed explanations and code examples designed to build your skills step-by-step. This course is designed for beginners in automation and QA professionals who want to expand their testing toolkit beyond standard functional scripts. No prior experience with visual testing is required. Start building more robust web applications by mastering visual automation today.
