# Test Coverage Analysis

Find out whether your tests are actually worth much

## What this does

The tests are written and passing, but that does not tell you whether they cover what matters. This helps you assess the quality of the coverage you have, across structure, mutation, requirements, and API and integration, and helps you choose which analysis to run and read the result.

### Top 3 things it does for you

- Judge how good your existing tests really are
- Choose which coverage analysis to run
- Make sense of a coverage number you were handed

A scan is named by the exact content it read, not by a version number. A different version is a different artifact, and nothing here applies to a version AIR has not scanned.

## Questions

### Is Test Coverage Analysis safe to install?

AIR scanned this exact version of Test Coverage Analysis and flagged nothing. AIR's verdict: safe. The verdict is named by the content that was read, at commit 8539779375f4, so it cannot drift onto a version nobody scanned. The full report is at https://airmarket.ai/security/test-coverage.

### How do I install Test Coverage Analysis?

Open https://airmarket.ai/app/test-coverage on Air Market and use the install action: Air Market hands Claude a prompt naming this exact skill, and Claude sets it up.
