# X_COVERAGE_UNMEASURED

## Means

coverage was read from a suite that did not measure it

## Typical cause

three shapes: no lcov record names the package at all, so the percentage is over nothing; the suite wrote no report because it never finished; or files with executable code have **no** lcov record, which makes them absent from the percentage rather than counted as zero — the one direction an unmeasured file must never move it

## Fix

`bun test --coverage packages/<pkg>` and fix what it reports. For unimported files the finding lists them: import each from a test beside it
