 "what_it_is": "The tester that runs a page through every engine: Chromium, WebKit and Firefox at phone, tablet and desk — page errors, console errors, missed loads, sideways overflow, the buy button above the fold, the one-add law, THE WALK (the whole page scrolled at a thumb's pace with a reload sentinel) and THE WEIGH-IN (peak memory and the deck at the peak); and the Apple route — a Mac's Safari, the iOS Simulator, or a plugged-in iPhone — for the real ceiling. A whole theme runs page by page with a per-engine summary. The full room runs on a Mac; a sandbox with Chromium alone says so.",
