What To Expect When You're Expecting: A guide to Regression Testing
summary
Claims that visual regression testing catches UI breakage by comparing screenshots, using Puppeteer + Resemble.js + Jest/Enzyme to launch headless Chrome, capture pages, save diffs and assert a 100% match threshold against golden screenshots. Tests emphasize speed, reliability and small modular checks, show diffs when gutters or fonts shift, and let teams decide whether to update goldens. Demo code is promised but not yet hosted.
