summary
Argues that frontend testing shifts from pixel‑perfect checks to measurable quality: load speed, validity, accessibility and SEO matter more. Recommends using Lighthouse with 3G throttling to get audits and concrete fixes (image compression, lazy loading, remove unused CSS), using an HTML validator and an HTML tree tool for heading hierarchy, and using BrowserStack screenshots to cut redundant cross‑browser effort. Cites work across 190 projects and a poll splitting opinion roughly 53/47 visual versus quality, and shows Lighthouse reports produce actionable remediation lists.
