Product overview: illustrative concept screen

01 / Overview

A quality concept that scans a repository, ties coverage to user flows, flags untested critical paths, and drafts tests for review. Results appear in CI so regressions in coverage are visible.

02 / Challenge

Overall coverage percentages hide the fact that the most important flows may be the least tested.

  • /Coverage numbers ignore business criticality.
  • /Writing missing tests is slow.
  • /Coverage regressions go unnoticed.

03 / Proposed capabilities

  • 01Map coverage to critical user flows
  • 02Rank untested paths by risk
  • 03Draft tests for human review
  • 04Comment coverage changes in CI
  • 05Track gap trends over time
