Visual Testing with Chromatic and Storybook for Design Systems

Modern user interfaces are complex, with hundreds of component states that can easily break with a single CSS or layout change. Checking every button, dropdown, and modal manually is slow and error-prone, leaving your application vulnerable to unexpected visual regressions. This written course teaches you how to automate your UI testing workflow using Storybook and Chromatic. You will learn how to isolate components, document their states, and run automated visual regression tests to catch visual bugs before they ever reach your users. What you'll learn: Understand the core principles of component-driven development and visual regression testing; Configure Storybook to document and isolate UI components in various states; Integrate Chromatic to automate cloud-based visual testing and collaborative UI reviews; Identify visual bugs across different browsers and viewport sizes automatically; Apply modern accessibility standards within your Storybook workflow using automated testing tools; Connect your visual testing suite to continuous integration pipelines for automated validation. You will start with the fundamental concepts of UI testing and design systems before moving on to practical configuration. Through clear written explanations and step-by-step code snippets, you will build a robust testing workflow from scratch. This course is designed for web developers, UI engineers, and designers looking to automate their quality assurance process, with no prior testing experience required.
