95% Coverage Test Matrix

This panel has two parts: at the top, three summary numbers — environments needed to cover 95%, the actual coverage of this list, and how many environments are new versus the previous period — and below, the full list of OS-by-browser combinations ranked by user share. Each row's bar shows cumulative coverage up to that row, and rows with an above-average bounce rate carry a "high bounce" badge. The "Download CSV" and "Copy for QA" buttons export this same list as-is.

This panel serves as the QA team's roadmap before every sprint. Imagine that before a QA sprint you want to know, at a glance, how many environments need testing this cycle, whether a new one (say, a fresh browser version) has entered the picture, and which environment to start testing from. This panel answers exactly those three questions: the summary numbers set the overall test plan, the "new" badge tells you where to be more alert, and the ranked list tells you which environments to test first, top-down, for the most coverage with the least effort. With "Download CSV" or "Copy for QA", this same list turns directly into a team task with no extra work.
