Spot the Difference - Automating Visual Regression Testing

Explore visual regression testing automation in this 46-minute conference talk from WeAreDevelopers World Congress 2018. Examine common pitfalls of relying solely on end-to-end automation testing tools and discover how visual testing can enhance your testing strategy. Learn about the motivations behind test automation, drawbacks of manual-only testing, and typical end-to-end automation challenges. Gain insights into visual testing fundamentals, potential issues, and effective solutions. Dive into topics such as the test pyramid, hourglass anti-pattern, unit test coverage, fragile testing, and ideal testing approaches. Investigate Selenium, browser compatibility, execution speeds, and maintainability in UI testing. Understand the concept of "spot the difference" in visual testing, explore various visual testing options, and address challenges like base images, viewports, and dynamic content. Conclude with a comprehensive summary of visual regression testing best practices and considerations.
