See the Product the Way a Tester Does

A coverage number is a poor substitute for seeing what was tested.

Which screen? Which field? Which state? Did anyone try the boundary cases, or only enter a perfectly ordinary value and click Continue?

/carbon-map builds a persistent product quality map around pages, screenshots, widgets, paths, and journeys. It gives testing evidence a visible place in the product.

Move from the screen to the question

Select a page, inspect an element, and explore the available input cases and behavior. A screenshot or element close-up helps locate the issue; the case record explains what was tried and what remains a candidate.

The map separates functional risk from business risk. A small formatting failure and a checkout interruption may have very different consequences. Adjustable weighting lets you steer the next testing and regression-automation backlog toward the tradeoff you care about.

Time and cost figures are estimates unless actual measurements support them. They are planning aids, not a receipt for savings.

Keep the map when the product changes

/carbon-map inspect the local checkout journey; highlight untested field boundaries and changes since the previous build

Notes, priorities, and custom checks persist. Later builds can reveal added, changed, and missing surfaces while retaining historical context. If a field returns, the testing knowledge associated with it should not have vanished with the previous screenshot.

The interactive view can also be exported as an offline ZIP snapshot. That snapshot is shareable evidence, not a live connection or a new test run.

The interesting part is not the visual effect. It is being able to point at the product and say, “This matters. Here is what we know. Here is what I want investigated next.”
