Visual Regression Testing with Wraith
1 like1,037 views
Visual regression testing is a technique to test styles by comparing screenshots of a website over time to detect visual changes. It helps ensure plugins or code updates don't break the appearance of a site. Wraith is a tool that automates visual regression testing - it takes screenshots of a site, compares them, and flags differences. While Wraith currently lacks flexbox support, the next PhantomJS version may include it. However, PhantomJS' main developer stepping down creates uncertainty over its future maintenance.
