How it works
Count positive hit counters. For line coverage, combine statements starting on the same line using the largest hit count.
One of the sample’s two statements and one of its two branch paths are covered: 50% for each.
Limits
Raw Istanbul file coverage, not summary JSON or source-map remapping. Zero-item metrics have no percentage. Counts do not establish test quality or enforce a threshold.
