+Automated Visual Regression Testing can help you detect when the layout of a web page has changed. Instead of comparing pixels from screenshots, layout differences can be detected by comparing HTML tags and attributes with a baseline. If a change is detected, it could mean that something broke, the web page was redesigned, or dynamic content changed.

+In conclusion, open source automated visual testing tools are being built directly into test frameworks, and this trend is growing. Just like many years ago when free Wi-Fi at coffee shops replaced Internet cafes that charged money for Internet access, open source tools for visual testing will replace their paid counterparts in time. You'll remember this next time you're sipping your Starbucks® Pumpkin Spice Latte with your free Internet access, instead of paying for Internet at cybercafes.
