Find out what parts of your app are missing tests. This tool scans your routes, components, APIs, and user flows. It then compares them to your existing test files. You get a clear table showing what is tested and what is not.
The coverage matrix shows each area with a status like covered or missing. Uncovered areas are ranked by business impact. Critical features like auth and payment come first. You also get a suggested test plan with effort estimates.
Finally, you can choose to auto-generate tests for the top gaps. This helps you quickly improve your test coverage where it matters most.
